There are 2 additional options, the Willfire MFG collar and the Allegheny Tapered gas block. The Willfire collar is like a Gordon collar but for 12.5 carbine govt profile barrels. The Allegheny gas block has an integrated taper so you can skip the collar in the rear and have a very compact AE/OC M5 setup.
Thanks for the info. I just checked out the site. I have 2 rifles that run the OCM5 but want another. Is the gas block for a specific length barrel? I read its purpose is to go as short as possible but that can be several options.
@@scott2228There are 3 different length versions of the gas block on the site. Each one lists the approximate compatible barrel length for each gas system length at the bottom of the Description field
Appreciate the info. I looked at all 3. I’ll strongly consider these. Leaning towards a 15.1” barrel but still in “design phase.” I can’t stop myself from starting new builds once another is complete.
Thank you for showcasing that over the barrel muzzle device. Makes my life easier. Also thank you for addressing how the original collar attaches. I too was also wondering how one would mount the collar on an M4 profile barrel.
For you guys wanting to do this on an 11.5 barrel or any other barrel that doesn’t have enough space, you can use the Otter Creek PTB (think that’s the name) adapter. It basically extends forward the space you need instead of coming backwards over the barrel.
@ there is a video showing you can but the longer brake means the front gap between first baffle and break is shorter which would lead to shorter baffle life. Not sure how it would perform in terms of sound reduction and blowback.
2 questions: what’s the flashlight mount on the top upper? What length is the barrel of the bottom upper? I have a 14.5” I’m considering getting the OTB for but not sure if it’ll be too long
i have a 11.5 h&r i would like to suppress, im looking for insight as to if the otb mount will work correctly with my barrel length or if i will need to get a 12.5 barrel. thanks in advance
Probably an odd question, but does that OTB device have enough on the end to be 16" OAL for a P&W on a 14.5? Thats what I'm looking at for my current build but if it doesn't bring it out to 16 OAL looks like I'll be paying another tax stamp
I _have_ an M4 collar but I am finding it is hard to find barrels that actually fit it! BA don't, Aero don't. The most common issue is the step is too far from the shoulder for some reason.
Aero Precision rifles all use Ballistic Advantage barrels, maybe it has something to do with that particular manufacturer. Have you tried using a government profile barrel from any other manufacturer like BCM or Daniel Defense?
As far as the ops inc brake install, did you use an accu-washer for the shim? It looks like an accu-washer and another shim to get the correct spacing for the can.
@@blakejake9618 There's a lot of debate about the correct way to install those brakes. The OCM OTB single piece adapter specifically says not to use a crush washer. Centurion arms sells their brake with a crush washer with the reasoning that the collar will align the suppressor. I tried the crush washer and it seemed to work fine. But I ended up going with an accuwasher and shim to get the brake to time correctly and have enough clearance for the can to get the proper 7-10 turns for installation. E
Are you still able to mount a bayonet with these otb mounts? Thinking about doing a 14.5" m4a1 with one of these cans, but still wanna put my pig sticker on just cause.
What length is the barrel with the Otter Creek OTB mount? I was wondering if you could fit this on an 11.5" with a fixed FSB. I know the website says you need a certain amount of clearance, but i dont have the barrel yet. This will determine what length I purchase.
@@WestlehSeyweld I think that has more to do with the pressure on the suppressor with a muzzle break instead of barrel length. As you can see in the video I have a 12.5 and it’s right on the a2 sight. If you have a low pro gas block you’d have an extra inch or so of space because the sight isn’t extended off it.
@@blakejake9618 that line is from the barrel lengths section on their page for the OCM5. It also says on the The OTB Muzzle Brake that it needs “a minimum of 2.05 of exposed barrel MEASURED FROM THE SHOULDER” I always thought 11.5s had around 2 inches past the fsp. But hey, I don’t own any of this stuff and will take your word for it.
@ look up a 10.3” barrel with a FSP. It’s basically cut off right at the end of the sight. An 11.5 is only an extra inch. I just don’t want you to waste any money you don’t have too.
What’s the bore diameter of the muzzle brake? I’ve seen that Allen engineering makes a .30 cal over the barrel suppressor but I haven’t been able to find any information that indicates how I would go about mounting it to a .308 gun
I just ordered the ocm5 and ops Inc brake & collar. I’m building this one from the can rearward, basically. Not going for any clone correct builds here, I just met a customer at the range with a mk12 setup and decided I had to have this. Interesting collar solution with the gb/collar combo, I’ll definitely look into that. I know most people would be putting this can at home on a stainless barrel but I’d really like to stick with Chf 18” since I shoot usually a couple times a week, higher rates of fire sometimes, and the gun may hit a high round count pretty fast… any recommendations on a Chf rifle gas 18” barrel? Does anyone even make a Chf spr profile barrel?
I’m trying to do a 13.7 mid length upper with the OTB sleeve but don’t want it to look weird. What’s the overall length on the upper that you have with the OTB sleeve. I would just SBR it but it’s a duty weapon and that’s against policy.
@@InkwellFoto it worked fine. It’s arguably a better system, but not by much. I needed a new barrel anyways and I thought the collar system looked cooler.
I’m waiting for my OCM5 to clear background before I pick it up. I had a question, maybe someone here with the knowledge can help me. I was looking at my rifles and started wondering if I had enough barrel space, not covered by hand guards. Doe anyone know how much uncovered barrel space/offset is needed once the can is screwed on?

I run my OCM5 on an OPS12 profile SPR and a 12.5” using the OC OTB mount. Amazing CAN. Otter Creek crushed it with this line.
Thank you for showcasing that over the barrel muzzle device. Makes my life easier. Also thank you for addressing how the original collar attaches. I too was also wondering how one would mount the collar on an M4 profile barrel.
I had a pair of Mk12s beside me at the range recently and I was shocked at how quiet they were… sounded like a suppressed 22 with super hot ammo.

Good info. My OCM5 lives on my Mk12 but be cool to use it on another build.
A MK12 is the next on the list for me.
Thank you for the explanation. You are very well spoken (unlike some people on gun youtube).
Thanks I try to cut the BS. RUclips 12 years ago was much better and less hyper lol.
Thank you for this. Very cool.
Thanks for sharing. Unrelated to the collars and OCM 5; who makes that scout mount for the FSB you have on the top upper?
The red dot rail is a Leupold and the flash light mount is a GG&G.
Thanks for making this video, there is not too much info out there about these set ups.
Spikes Tactical Mounts also work as their Suppressors are based on the AE cans.
Do you use
The allen suppressor on the spikes tactical mount?
@ there is a video showing you can but the longer brake means the front gap between first baffle and break is shorter which would lead to shorter baffle life.
Not sure how it would perform in terms of sound reduction and blowback.
In Mogadishu, like Gordon's rifle. They were using 14.5 with a collar.
2 questions: what’s the flashlight mount on the top upper?
What length is the barrel of the bottom upper? I have a 14.5” I’m considering getting the OTB for but not sure if it’ll be too long
If I had a 12.5” Government Profile barrel and I wanted to go with OCL parts, would I need the M4 Collar or the SPR Collar?
I really dig the camo paint scheme, gives owen gun vibes. What type of paint and colors did you use?
It’s the Arizona Response Brush Stroke kit. I love it. I’ll post a video of my rifle one day.

You would need a 12.5 for the clearance. The Midway adapter is what you need I believe. Check the measurements on his website.
Do 14.5 like the real Gordon rifle. Maybe with out there cans you have to go lower.
Probably an odd question, but does that OTB device have enough on the end to be 16" OAL for a P&W on a 14.5? Thats what I'm looking at for my current build but if it doesn't bring it out to 16 OAL looks like I'll be paying another tax stamp
I don’t think there’s any way to P&W it, but I imagine it would. Mines a 12.5 SBR.
This is what I wanted to know.
Good info - what's that fsb mount?
It’s the GG&G single side mount
Nice!! Thanks.

@fakename287 I've sent a few emails to see if someone can put some calipers to barrels
@fakename287 DD is visibly wrong, though.
As far as the ops inc brake install, did you use an accu-washer for the shim? It looks like an accu-washer and another shim to get the correct spacing for the can.

12.5 minimum. That’s what this is.

Do you think that one piece deal will work on a sage dynamics 12.5 patrol length barrel?
I’d imagine so. You may have to saw off the bayonet lug worst case.

its a 12.7 carbine. You should be good on a 13.7. The OTB and the M4 collar set up are the same length.
Youd probably have to do a 14.5 pinned to hit 16 inches.
What mount would work best for my 14.5 socom upper? And how gassy is your setup?
Finally. Someone with the r8ght size barrel as the Gordon carbine.
@@johnmarsh6337 what do you mean?
The M4 collar system. And it’s not bad if you’re right handed
Would you do the otb muzzle break or the flash hider?
Not if you ever shoot non-suppressed. The brake is a flame thrower.
How long is the OCL OTB flash hider?
Unfortunately I no longer have it.
@blakejake9618 did you like it?
@@InkwellFoto it worked fine. It’s arguably a better system, but not by much. I needed a new barrel anyways and I thought the collar system looked cooler.
What length is that bottom barrel??
Both 12.5, but that one was cut down so it could be a little off.

I was looking at my rifles and started wondering if I had enough barrel space, not covered by hand guards. Doe anyone know how much uncovered barrel space/offset is needed once the can is screwed on?
Depends on which mount. The OTB needs like 2 inches
Will the OCM5 fit on a barrel of a non-AR 5.56 rifle like the Tavor or Hellion?
As long as the OTB mount fits it would yes. And it fit my HBAR which is really thick.
Did you go with the heat treat or nitride OTB?
This is the nitride. The heat treat has a gold color to it.
Just shot mine for the first time today

Over half of the suppressor is below the muzzle, it probably barely does anything. You only get 2 inches of suppression. Very gimmicky
It is one of the quietest on the market. You have zero clue what you’re talking about.
