- NOTE: Torque T25 side plate screws to 45 in*lbs (5 N*m). NOT 90 in*lbs as mentioned in video. Installation video of an HBI CZ Bren 2 MS Handguard. Written installation guide is available here: hbindustries.n...
Just installed mine today. Looks great feels very high quality. Nice to have a manufacture that puts out helpful videos on installation rather than cheap paper instructions
Honored to have you running our parts on your Bren, and thank you for the kind words. But let's be real... our video's could all still use a little more work :-)
FYI: I just got done installing this handgaurd. Cz is using way to much thread locker. I had to drill out 3 screws that I stripped. Use some heat on the stubborn screws. Great handgaurd, CZ needs to start using these.
Same issue. Stripped out my two
Lower screws. Taking it to lgs tomorrow
I used a heat gun and a small ratchet… easy work
Same happen to me..
I got my 2 Handguards installed Saturday and I highly recommend them. Very well made and looks great! I also highly recommend the trigger and charging handle upgrades.
I've got trigger and love it! But is there any benefit in charging handle besides esthetic?
@@dennisk5054 Its longer, metal and makes charging easier with optic mounted so you don't lose skin on knuckles :)
My area of working with guns at a munitions company, inspired me to question the handiwork demonstrated in the assembly video.
I’m not here to hate on HBI, I only have used one of their products in the past.
First of all, a little bird let’s say, over at CZ gave me a rundown for the fore end assembly.
Now it maybe cause we are talking 4 screws instead of the stock number, but 10 NM seems a tad high.
CZ recommends 8NM for the stock fore end assembly.
Furthermore the orientation in which the screws are tightened matters as well, starting from the left front screw, work your way to the front right screw.
Finish off with the left to right rear screws as well, the gist of it is, always start with the left front screw and end with the right rear screw for your torque path.
Again this is only my knowledge based the on stock arrangement.
I heard word of some chopping brass so here’s my suggestion, cheers!
That little chuckle at 7:20 should've alerted me to the task/endeavor/nightmare I was about to undertake with those bottom t25 screws... thanks for the video and CZ if you're listening, PUT DOWN THE LOCTITE !!!
I'm working on this myself now, I managed to get one out but this second one by the magwell is taking some serious herculean effort!
@@boreasthenortherndragon6217 it's been a few years but I believe I used a heavy duty soldering iron to heat up the head to break the bond but can't remember if I had to make a longer heating element out of a piece of #6 solid copper grounding wire to reach it or not... if it's that tight try this before stripping the head out
This is the handguard that should come on it from the factory. Very nice!!
Finally SOMEONE listened!
The bottom mounting rail appears to be stabilizing the barrel and factory hand guard. And it’s secured super tight with 5 screws. To remove that without replacement has got to be affecting the performance and stability of the rifle. Why not design a hand guard that preserves the factory integrity of the rifle?
Holy...shit...that looks 1000x better! I was planning on buying a different gun, but after seeing this, I think I've changed my mind.
I would love a version that reverts the look of the MS to the S version.
Get the Preston Precision Pic rail kit for the stock handguard and youre 90% there.
@@Henry14arsenal2007I purchased a set, definitely gets the gun looking closer to the 2S.
Very nice! Can’t wait until some stocks become available for this weapon
First! 😁👍 Nice handguard, can't wait to actually grab a 11" 5.56 pistol when they start getting easier to find!
Yeah they made this look easy. Freaking CZ with impact wrench those screws in with all the blue loctite. Took my smith 20 plus mins with heat and tapping to get those off. Almost as bad as a scar. lol
Just in time to install on my new 11 inch 7.62x39 on Monday
How well does this handguard mitigate heat dispersion? The original handguard for the 11 inch barrel becomes piping hot and is severely annoying.
I'm sold, will you be making it in additional lengths? If there is a slightly longer one that fits the 11 inch specifically I'd be very interested! I'd also love to get a 14" Bren 2 pin and welded to turn into a rifle and one of these in a longer version would be amazing!
Would love to see longer ones as well.
Mattycakes so after spending some time in the forums one user brought up a good point. Only thing that would make longer rails more difficult is still allowing access to the gas system without having to remove the rail. Not impossible, the scar has tails that do it so Bren can too
Smoov Cat yup that’s the rail I was thinking of when I commented. That’s awesome, I did just see another very popular rail manufacturer post an Instagram story image of the Bren 2 in stock form. I’m assuming that means they are working on something. For respect of HB I don’t want to place that info here.
just installed mine today, took me a bit on the bottom Torque screw closest to the chamber, ya "F" that thing. Had to get an impact driver out to get the screw out lol. All good now.
Damn that looks so good.
How rugged/reliable is this handguard? Will it stay tight and straight with hard use? Thanks for these great products. Will you have anything for the military S model?
The guy on the video said to torque the the screws to 10n/m or 90inch/lbs the instructions that I got in the mail with the product say "45in*lbs or 5N*m"
Which is it? Have I over torqued my system?
We need to remake this video... The early guns were fine at 90in*lbs (before even factory had released an official spec/armors manual), but we found some carriers in the newer guns can start to bind/drag at that torque. 45in*lbs has proven perfect in all guns to date (12/2020). 90in*lbs will not hurt the hardware or the trunnion. But if you think that you have over torqued the washers or have concerns please just email or call us, we would be happy to send you a replacement set of nord lock washers if you need them.
I cannot get those forward screws out.
Still cant decide if this looks and feels better than the Preston Precision rail kit on the stock handguard.
I just bought a bren2 8in 556 so I'm all ears. Got my sub.
@Smoov Cat thats why you run it suppressed =). i just snagged a 8 inch 5.56 Bren 2 and going to use it with my Socom Mini Monster Suppressor
Yes yes yes!
Great Product - I have the 11" barrel pistol with a brace and this really is the best upgrade to the CZ BREN 2. The factory hand guard is too short, unless your a Battle Gnome or a Manlet. CZ should just give up on the "Factory Hot Mess" of a handguard and make this standard for the 8" and 11" pistols and use the longer HB Industries handguard on the 14" pistol. Besides the increased comfort and simplicity, the new handguard keep you from coming into contact with the hot gas block. Americans are by usually larger than Europeans, so this is a big help. Only the Scandinavian and the Finns seem to be our size or bigger, must be the Bear and Whale meat diet.
HB Industries was nice enough to include two QD mounts as I requested, so Thank You very much. I would suggest that this be standard going forward, as its very handy to be able to switch sides for different shooters.
finns are smaller than the Swedes..
Is this 70in-lbs or 90? The factory says one thing versus your instruction. Just wanted to clarify, thanks.
70in-lbs is sufficient. We had made this video before the CZ factory had committed to a torque spec.
HB Industries the instructions that came with my rail say 45 inch pounds. Which is correct?
@@pharmer92 HBI any update on torque specs for the 10.8 hand rail?
These directions are great but the screws were on so tight from the factory I ended up stripping them so bad I can’t get off. I’ll have to bring it to a gunsmith to see if they can hopefully remove
From my experience - the key for successfull removal of all these stupid screws is in non-using the factory key. I used the box from local hobby market (set of various extensions - sorry, I don't know the exact word in English, with small ratchet) and unscrew all of them successfully, without no damage...
Do I reuse the bottom mounting plate that was set aside at 8:15… I didn’t see where it was reinstalled.
No, the oem bottom plate is not reused. The HBI handguard (as well as some of the factory handguards) only require the two side plates for full retention.
Anyone else strip out the screws on the bottom 🙋🏻♂️😂 CZ‘s factory Loctite is ridiculous had the same issue trying to take off the barrel nut off of my CZ scorpion smh actually two out of the five screws on the bottom got strip had to drill them out Thing don’t have to use them to put the handguard back on
How did you get the screws out???
Can you please do a video on gas block removal and reinstall for you CZ Bren2 Suppressor service?
2 things.
1. You need to fix the torque measurements in the video so people don't break their parts.
And
2. HBO's customer service is on point. I broke a piece because of this video but they replaced it and gave me a second qd plate that I forgot to ask for upon ordering.
%100 great product, customer service, and company!
Agree; we will be making an updated video. (Note to others reading this comment, the instructions included with our handguards are correct)
What barrel length is that?
While trying to remove he ugly original hand guard, I stripped the screw on the underside of the barrel. One of the two near the end (mag well). Can a gun smith fix this?
Surefire still make that light with that mount ? I don't see it on their site ?
I just ordered this. Couldn't find any info on if it will fit the 2S until I read this thread. What am I to do??
You just ditch the bottom mounting plate? What is its purpose, didn't do anything for the factory handguard or did it? Why would CZ just ditch it too to make the gun lighter. I'm confused. Your handguard only has 1 small mlock slot at 30 degrees near the front. Is that for rigidity?
yea im wondering about the bottom mounting plate as well
The factory handguard uses a different (more flexible) manufacturing process. It is made from several components, just a different way to crack the nut. We only use a single MLOK slot on each side of our 7.8" handguard in order to shield the regulator gas (behind the slot).
takedown pin is really tight after installing the handguard. Any fixes?
Most likely related to the fitment/position of your stock adapter/brace/rear trunnion. Recommend loosening any screws or fasteners connecting your stock/brace/rear trunnion to your upper receiver, then installing the lower receiver, and finally re-tighten the screw or fastener that you loosened in step 1.
Do I need the barrel block that attaches to the bottom rail? I'm having horrible accuracy issues since installing this handguard and am wondering if I missed something. Also what are the torque specs? My instructions that came with the handguard say 90 inch pounds but others online are saying the spec is now 45 inch pound? Which is correct? Sorry for the questions but I love the gun and the handguar so I really wanna get this squared away.
We did recently revise our torque spec to 45 in*lbs on the mounting screws/plates. You might try staggering the torque sequence with a criss-cross pattern between left/right on the handguard mounting plates, just to ensure that the clamping pressure is evenly distributed. Accuracy with our handguard installed should the equal to better than observed with the factory handguard. Feel free to contact us directly at anytime and we will help get your Bren 2ms dialed in.
I am a huge Cz fan. However:
Dear CZ.
Please use less than $3.72 of loctite on your fasteners.
Perhaps consider upping the torque spec by 5-10%.
Removing some of these fasteners is scary at times due to the use of 1/10 of the worlds loctite being applied to CZ fasteners at any given time.
Thanks!
A CZ owner terrified of breaking your bolts.
Any idea when you'll have more in stock? I just picked up a new Bren 2 and I'm hankering to get this handguard!
We are machining more right now, should be about 2 weeks for both the 7.9" MLok and Direct Light Mount variants.
Does this make it a free float barrel? Is it better or worse with heat dispersion? Is it heavier, same or lighter then the hardware you take off?
The handguard free floats the barrel, many shooters report improved accuracy at longer distances. Our 7.9" bren 2 ms handguard (complete and installed) is 3.5-4oz lighter than the factory system.
@@hb_industries what about the heat dispersion?
@@tripleog404 i have noticed far less heat than the stock configuration
Looks great! Is it still easy to adjust the gas piston settings for us suppressed shooters?
Yes, our 7.9" handguards shown here are designed specifically to provide as much mlok and 1913 rail space as possible while still allowing tool-less access to the gas key for easy gas system adjustment(s)
@@hb_industries but removing the gas plug is a pain
Are the sights that come with these Troy sights? I like them and want to get more.
Your installation guide only says to tighten the screws to 45 inch pounds. This video says 90 inch pounds. Can you please clarify which is correct?
45in*lbs is the current specification. This video is from Dec 2019, and we need to make an updated version. This is our fault. Great question though! Please just let us know if you need anything else.
Glad for the clarification. I was confused too, my torque wrench only goes to 70 haha
@@Dawn_RaiderI checked with CZ and they recommend 70 inch pounds. That being said, I only did mine to 45 inch pounds. I'm terrified of the snapping screw lol.
@@redhead5222 you can kinda tell when something is off when you over torque it, the action starts to get super griddy. I tried 60 and had to back off to 45-50.
What is the torque wrench and the screw adapter on it in this video?
I think the torque wrench we used in this video is made by Urceri. But we have a few others here that work equally as well. We have found many quality 1/4" torque wrenches marketed towards the mountain/road biking community. Just due to the size and style of fasteners and range of torques (up to about 15N*m), they normally have both in*lbs and N*m scales and are very well suited to firearms.
Do you sell replacement screws for the handguard? I stripped one of the ones that came with your handguard and needed more. If not what spec are they?
Please just email us sales@hbindustries.net with shipping info and we would be happy send you some replacement screws
@@hb_industries Will do! thankyou
you guys are awesome. what's the brand of that torque wrench?
Lol I was wondering if I was the only one thinking that. Hard to find inch pound wrenches I feel.
@@biggboysouth right? other than the wheeler fat wrench (which works; but is actually a screw driver). They never replied though so i guess we gotta keep searching... LOL

@@hb_industries Awesome. Thanks for the reply. I just ordered one (URCERI 1/4-inch Bicycle Bike Torque Wrench Allen Key Steel Set of 9 (2.5/3/4/5/6/8/10mm T25 T30). Thanks guys.
@@hb_industries Thank you for the reply! I'll look them up.
I wish this video had a warning about the bottom hex screws on the stock handguard. Now i have 2 stripped screws and no idea how to remove them
Did you ever get those 2 stripped screws removed? I just did the same thing on mine. Going to see if I can bring to a gunsmith tomorrow to remove
@@cgtlea9202 not without doing a couple of hours of sketchy amateur gunsmithing unfortunately, honestly id say just take it to a professional and live worry free
@@Manch_Grapman yeah man, I started down that path of dyi gunsmith and it didn’t go well. Will definitely take your advice and take to a gunsmith. Thanks!
I need one of these in rifle form soo hard
should i use loctite when installing this?
ETA on the 10.2” handguard?
Hopefully they will re-think their design to include a way to access the piston without removing the HG. The 10" is a good idea, but poor execution.
If you have the 11inch pistol can the 7.5 inch handguard be used?
Yes, 7.8" handgaurds can be used on the 11" pistols.
Will that work on 8 inch 556?
Yes, our 7.9" handguard is designed for the Bren2MS 8" barrels and anything longer.
HB Industries ok great now lets get in stock I need one.
Do you guys ship to Canada?
I am wondering if I can purchase quick disconnect piece by itself? Would it fit factory handguard for carbine version?
Yes, our side mounting plates for the Bren 2MS (including integrated QD plate) are compatible with the CZ-USA factory carbine handguard.
@@hb_industries can it be purchased separately? I didn't find it on your website.
@@dennisk5054 Yes, please just call or send us an email sales@hbindustries.net. We make nearly everything that you see on our website in house, so it is easy for us to break out anything that you need :-)
@@hb_industries will do. Thank you!
dont try this without a power tool trust me
Is this the same for the new 10.8 inch hand guard?
They should have re-thought that longer handguard.. you cannot disassemble the gas system without removing the HG. You'll need to rezero.
Yes, installation is the same. We do however recommend starting torque of 45 in*lbs on the four T25 mounting plate screws.
@@hb_industries 45 is too tight, and I can feel the bolt or charging handle assembly catching.
@@RovingTrader possibly try to tighten the screws left/right in a criss-cross pattern? If this does not help please contact us directly via email or phone and we will get you taken care of. Your bolt should run very smoothly in the upper :-)
@@hb_industries I did that, and same issue around 40lbs on the rear bolts only. With nearly everything out, except the charging handle/sliding plate thingy... that piece is what is binding. The both seems smooth by hand.
Can I reuse the blue nord lock washers after I remove and reinstall the handguard for maintenance?
Yes, the nord lock type washers can be reused. We typically get around 10-12 uses out of them (at 45 in*lbs) before the blue rings delaminate or washers start to separate. If you over tighten the nord lock washers the useful life could be less than 10 uses.
@@hb_industries thx. Do you sell extra washers on your website?
@@rl1271 We do not sell them on our webstore, but if you call/email us directly we can take care of you :-)
the stock bren2 handguard is total ass. it has sooo many pieces to it.. HB handguard is a must
Will you be offering a version for the military version that shipped first?
The "first" version of the Bren 2 is known as the "S", the current version is known as the "MS". And while very similar, unfortunately at this time we do not have plans to produce a handguard for the "first" Bren 2S models.
@@hb_industries bummer with the rest of your Bren accesories fit the S model?
@@Malcolmmillsknows Yes, many of the parts are interchangeable. The triggers, safety selectors, charging handle, and stocks are all cross compatible between the Bren "S" and "MS" models
When will this gun be available with a 16 inch barrel?
That’s unknown, everyone’s been asking that question. If you’re not bothered by not being able to remove the muzzle device easily you could always pin and weld a 14 inch version and put a stock on it. But yeah no word on the rifle versions.
CZ should go to jail for adding locktite to these screws... stripped 2 of them.
Is that the 11" barrel or 8" ?
8
can you mount a sling on this hand gaurd?
Yes, in fact we highly recommend it 👍
How long is the barrel?
9"
Do not install this in your own. CZ uses like super glue on the bottom screws you'll end up stripping the bottom screws. Have a gun smith install this. Tbh have a gun smith install any thing hbi makes. Video makes it look simple, it's not.
I wish I read your comment before trying to do this myself. I stripped the bottom hex screws, now going to hopefully see if a gunsmith can get them out
Has anyone done some accuracy testing before and after this handgaurd install?
Great . My 2 screws on the bottom mounting plate are stuck 🙃
If you hit the screws really quick with a propane or butane torch it will make the melt the thread-lock and the screws should come out much easier
@@hb_industries thanks for the response! I will try that
Did you ever get your two bottom screws out? I'm having the same issue and ended up stripping mine trying to get them loose
@@cgtlea9202 yes. I ended up taking it to a gunsmith 😕
@@ChinoEEE yeahhhh I’m going to have to do the same
Really wish this was in stock. :/
We wish the same... but ARE machining more right now, ETA is a 2 weeks.
@@hb_industries I've already put my email in for notification. Patiently waiting, throwing money at the screen. :)
@@hb_industries assuming it's way longer since the apocalypse happened...
Stripped the t25 screws that are near the trunnion smh
Do NOT tourqe down to 90 inch/lb it's 35-45 this video is wrong.
This is a great video to fall asleep to! BORING!!
Looks like a missable product. Just of no interest to me. I’d rather trim it down than bulk it up.
The amount of hardware you remove drastically reduces the weight of the front end
Is this how you would install the 13.8 inch hand guard for the 14 inch cz bren ms pistol? Please help
Yes, the procedure is the same regardless of barrel length. The only thing to note about the 14.5" is that there is a bayonet lug that will need to be removed; the bayonet lug is affixed to the barrel using a 4mm roll pin.
