😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂… I literally laughed out loud when Caleb said ….when you have an optic over the back flip-up sight…. Common sense is not so common… very tasteful Caleb; I don’t think I would have been that polite, but you are a true gentleman, sir….😂😂😂😂😂😂😂
I bought a set thinking the size would be more towards the MBUS pro size. These are still pretty big IMO. It would help if you would have put a set of pros next to these for comparison.
Great and valid point...if you have an optic "over the top of them" why are you trying to deploy them....sounds like the internet experts just want to cry and complain about something 🤔...
Some of use run them as primary sights. I have one set each of Gen 2 and Gen 3, and I miss the wings on the Gen 3. I do like the adjuster knob on the Gen 3 front though.
The front site adjustment wheel has spring tension. You can see the grooves that the wheel locks into once spring tension is released. You have to slightly pull up then rotate in order to adjust. It is not difficult at all.
Have a set mbius pros, love them for my back up on my carbine.. Got lucky on installation too, the were zeroed for my application. Thanks for sharing your knowledge.
I bought the mbus2, and then a olight afterwards. I ended up trimming the lever wing off the one side to accommodate the light! Works just fine. Don't be afraid to modify your gear for your needs.
get the MaTech rear sight, and any front sight that uses the mil spec width post, which makes ranging target distance possible since the post matches E target width at about 170 yards.
I recently purchased a pair of these, and of course, Brownell's had the best price on them at the time, but they were out of stock on the color I wanted, so they lost another sale. Nice sights, so far.
Been running them on all my AR-15s for a long time. Andrew Tuohy did a durability test back in 2012. Turns out they only had a 1MOA shift, compared to the competition which was anywhere from 3-16MOA after being dropped 5 feet onto concrete.
I upgraded to the Gen 3 and the windage had to be adjusted almost all the way left. Didn't have that issue with the Gen 2. Yes, everything is straight and flat.
Not just in the military, when I was a kid in the 90s, they were just sights and my father and gpa raised me on buckhorn irons. Scopes around these parts hunting in southern OR make it more difficult in the thick brush
Wish I'd had that "no tool needed" front sight a few weeks ago. Would've made sighting in that much easier... My MBUS rear sight was a sinch. Gen 3 on my next rifle, then 😏👍
Just thinking out loud, but maybe if your optic craps out and you don’t have a QD mount, im assuming you’d have to leave the non functional optic on and pop back ups? But if you’ve placed your pad tightly fitting under the optic then of course you wont be able to do that. Im assuming thats why people are complaining about not having the side wings. Obviously it would just be fixed by moving that front sight forward a bit but I don’t know, I guess people run out of rail space on their 5 inch AR’s lol
I don’t like plastic parts or accessories on an AR and that is just me. I installed a set of fixed Daniel Defense sights on my build and not one complaint from me.
Next to fuckin impossible to adjust, don't buy em. Pop up button sucks on both too. Plus my front sight post fell out other day, thank God I found fucker before wife vacuumed. Buy mbus 2
I still have a bruise on my thumb after trying to adjust the front sight of my friend's mbus 3. Apparently, you can push up on the gear to make it adjust easier but I didn't know that at the time.
I just got a set of these last week and put them on a rifle with an Eotech so it's not mounted under anything. The rear sight worked fine, just like the older model. I had a difficult time getting the elevation drum on the front sight to start turning, but it worked fine once I got it going. I'd suggest anyone getting these get the drum to turn easily before mounting it on your gun. Lastly it seems like I had to move the front sight up pretty high to get my shots low enough on the target. I like them and will get them in the future.
Caleb, fellow Louisianian here. Love your content. I picked up the MBUS 3 sights, and the front sight adjuster is hard to adjust. Are there any pointers you can share?
Looking for sight(s) to put on my shotgun that are raised up a bit so I don't have to lean my neck down so far to aim. I have a fiber optic site on the barrel currently. Any suggestions? Looking to take 30ish yard shots at turkey with plans to hunt other birds. I was so close to my first successful hunt yesterday...
Man I've been wanting a good set of either Knight's iron's, but just can't afford them🤦 or even a set of Armadine's even, but again just out of my price ramge😒
I got the aluminum ones from Amazon for about 35 bucks and they work well enough. I have an optic anyway so I'm okay with them, just get the ones that have the best reviews. If I didn't use an optic I would probably get something better.
My first BUS was an MBUS. I now run ultradyne c4. Once sighted in, you get on target if you see through both holes. Not a great MOA but it's meant for a back up. If you see your target it's getting hit.
Looking at how slim these gen 3s are, I’ll have to pick up a pair and see how it works with my exps3 and g45. I have to run the g45 all the way back so that stopped me from thinking of getting back up irons
I just bought the Gen 3 set and I think the Gen 2 sights are quicker to deploy. The Gen 3 front sight doesn’t appear to be working properly so I sent Magpul and email. I can’t get the post to adjust no matter which way I turn it
My primary gripe with these is very visible in the intro, they don't lay flat to the rail. It looks kinda stupid how they're always sort of camming upwards, I don't think the 2's did that so much.
Do you get pinched when hitting the release on the top? With my 2’s I like using the wings to deploy the sights otherwise I get pinched when I push the top.
Idk how comfortable I feel with that front sight being so easy to adjust with everything exposed like that. Seems like it'd decrease reliability since it's now easier to accidentally have it come off zero.
No matter what optic, Red Dot or Holographic sight you plan on putting on your AR or similar rifle the very first thing you should do is put some back up iron sights on there. There is no good reason not to have them. I went with the steel PRO Series for both of mine.
I could see not having the wings being an issue in some setups. My rear sight is sort of under my red dot and if my battery is dead I'd have to take the red dot completely off the rifle to use my backup sight with this new model.
Besides my rocket comment, I’ve been using B&T sights. I what I like about them is they have a folded non-adjustable sights, and flip up adjustable sights which I find pretty awesome. Then again I have been running ‘irons’ only as of late.
The MBUS3 front sight is extremely hard to turn that tiny wheel, (I believe the wheel should be a larger diameter), anyways. Are MBUS3 compatible with an MBU2?... Can I use a MBUS3 rear sight and a MBUS2 front sight???
Those do look really cool. I've had the Gen 2 MBUS for about 3 years, and they're fine. I just got into the AR world in 2019, so I didn't realize what a change these are. The Gen 3 does look a lot slimmer and now I need a set on the next build. One point of disagreement, Caleb - I setup a red dot, 3x magnifier, and the backups on a build, and the magnifier mount worked out that I could get the eye piece to stand out over the top of the MBUS rear sight, but only to the joint. So, I have just enough room to flip up the sight, but only if I deploy from the side. The magnifier is on a flip-out mount, but this allows me to deploy-then-flip-over in one set of motion with my off hand rather than to flip-out-then-come-back-to-deploy. So, I get what people complain about without the ability to deploy from the side.
Never used the gen1s...use the gen2s on kiss rifles with A2 front sights...I like the PROs..have had several sets over the years...when the cost comes down abit on the g3s...might try them.
I run pros, so these still look a bit bulky to me. The only thing is that they deploy easier/faster than pros, but at the same time, i hope i never really need to deploy them. :)
It's been a good ten years ago that I bought two sets of MBUS sights (the first gen?). Both sets, all four, broke below the attachment screws. You can say that I tightened them too much but I didn't. Never before or since have I had the same issue with other sight mounts. I have not tried later generation MBUS versions since I always live by the rule "Screw me once, shame on you. Screw me twice, shame on me."
Got a set of these that should be coming in today. The size and weight numbers look great for my build. I've got some a gen 1 set that I use, but they are a bit chonky. Weird that he mentioned the MBUS 3 are heavier. The numbers on their site show that the MBUS 3 are lighter than the Gen 2. 1.06oz vs 1.3oz on the rear and .88oz vs 1.2oz on the front, now they do measure the MBUS 3 in grams and the traditional in ounces, but the conversion to says the 3 should be lighter...That's part of why I wanted to try them out, I hope the numbers are correct. Maybe it's just density or something that is making it seem like that to him.
Hmm idk but they are back up sights. They are not going to deployed that much by regular users. But if you need reliable sights then your better off with steel
@@johncox2865 they were dummy hard to adjust and I didn’t like the way they deployed. I returned them and just got the polymer ones. But I kinda wanna get these new ones haha
I think this may be internet rumor (Caleb mythbuster material) Mine have gotten pretty warm over the years. I guess there is a disclaimer on the Magpul site not to mount the on a front sight gas block. But I think for normal use on semi auto ARs with the sight mounted on a handguard it would be hard to get them hot enough to melt. Maybe Iraq veteran 8888 may have some knowledge of this since over the years he has got some ARs pretty hot
If you have the Gen 2 and don't upgrade to the Gen 3 there is 100% chance you will be killed in a shootout.

Added front and rear MBUS 3 to my M&P 12 Bull Pup. Robust backup sight.
Great video
I just ordered up a set of this gen 3. Looking for to installing them.
Leave Caleb alone, he just works here 😂
I outfitted most of mine with MBUS 1....now I have to fix them and get MBUS 3
I have both types and I honestly like the side deployment button better. Faster and more comfortable action
Big fan of Meprolight sights.
Whats up Caleb! 🇺🇲☝️
WHY does no one put the camera down the line of the sights? Just show it.

I installed a set of fixed Daniel Defense sights on my build and not one complaint from me.
They should come up with shotgun specific and ar9 specific maybe? HK ring? Would be fun
I might actually start buying these now! I only went with the faddefense ones mainly cuz of not needing a tool to adjust them
Great overview, but I'm almost certain the MBUS 3s are lighter than the 2s
How easily does that front sight adjuster spin?
(concerned about inadvertently changing the zero)
The one I have is very stiff.
Also use a paint marker on anything adjustable on your guns, so you can easily check if it moved.
Next to fuckin impossible to adjust, don't buy em. Pop up button sucks on both too. Plus my front sight post fell out other day, thank God I found fucker before wife vacuumed. Buy mbus 2
You have to pull up on the button to turn them. They are made to be that way so they don’t accidentally turn under recoil.
