The Magpul MBUS. They had a pre-order in late Feb/early May...they should be releasing them for mass production sometime this summer...

I can't wait for them to come in. I've got an SBR build that has all magpul furniture, rail covers etc, and it is begging for a set of FDE MBUS.

not to bring thi back from the dead, but i have some on my 20'' rifle. theyre not bad, kinda bulky in my opinion while down, but hav e the quick pop up function and seem to be overall good sights. they also seem to take up a decent amount of space on the rail, but it might just be me. good thing is thatg since theyre polymer they are quite light

I am running one on the back of one of my rifles. I do agree it takes up a little more room on the rail but it's with in reason. So far I like it alot. It's a reasonable option for buis. For the shtf I would choose iron, but so far so good.

What paty of "Back Up IRON Sights" is made of plastic? If you have to use back up sights, then your primary sight is down. Want to trust your life to plastic? I broke a set within the first 5 seconds I had them and immediately threw them away. I guess they work great if your rifle sits on a shelf to guard dust bunnies, by my rifle is a tool and needs to be as dependable as possible.

Well given the wide use and broad user acceptance I would suspect you received a defective item. You can and should just call MagPul (they're in Boulder after all) and tell them what happened. At the very least you'll get a replacement set that you can sell to someone who would get actual value out of the BUIS.

If they break onece, they can break again (I've demonstrated this on another set). When your life is on the line, I would rather pay more money for dependable sights than waste money on something waiting to break.

uhhhh, anything can break. i will guarantee you someone somewhere has had any piece of equipment ever built break down. it happens. i have a cousin who uses these in iraq and they seem to do him just fine. its my guess his weapon is more of a tool than yours and his life is on the line more than yours.

i have a set and theyre ok. for the price, its hard to beat. often a set of flip up sights will cost about $200 or so, i got my magpul set for $60. the one thing i don't like is they are bulky. my rear sight causes some problems for my scope. my burris pepr mount could get the scope over the sights with a bit to spare, but with my ad recon mount it BARELY fits over the sight. also, theyre pretty dang long.

You seriously threw them away? If you still have those broken ones, I'll take them off your hands.

Guess you missed my point, you could have had them replaced and then sold the new set. MagPul is good that way.

All said and told it's a BACKUP Iron Sight.. not primary. I can't talk from a point of personal experience with the MBUIS, I run Troy sights on all of my AR's, but I wouldn't have an issue with running the MBUIS simply based on anecdotal evidence. Given MagPul's significant and diverse customer base, if there is an issue with the MBUIS as an over all product to the degree you're indicating, it would have the children at BARFCOM and many of the more active folks at places like M4 and LightFighter raising a serious stink. To my knowledge, no such mass concern has arisen.

But hey your mileage may vary

You are correct, it was a guess.....you don't know what I do or where I deploy to. Aside from that it doesn't matter where you are; if your life is on the line, waiting in line at the PX in Baghdad or in downtown Denver, it's still on the line.

Sorry, If I wouldn't trust them than I will not give them to someone else to fail on. Besides, they ended up in a dumpster. Crap is crap, regardless of who's rifle its on.

I just don't like them. Yes, even good equipment breaks from time to time; but I've broken every set of these that I've bought (within minutes). Their other products are virtually indestructable, but the sights aren't worth the money in my opinion.

This is coming from the same guy that says it's okay to use birdshot as a defensive round.

I understand they are made of polymer (plastic) whatever. As for using "plastic" parts on your AR.....buttstock and grip are also plastic...as are various quality AR components these days....good luck effectively using your rifle if any other plastic part on your rifle breaks...handguards, grip, buttstock...

Actually, in the confines of an average house birdshot works just fine. You fire a round of birdshot at someone 21 feet away, it's still traveling in a solid column when it hits them....like a freight train. The nice thing is, it won't go through too much because once it starts to all those small pellets will start losing their energy. Less of an overpenetration issue than pistol ammo. I have a couple boxes of the super short Aguilas using birdshot to go in my 590 for home use. This is with a 12 gauge, mind you, not a .410.

If I could only have a 12 gauge shotgun with birdshot for home defense, I wouldn't feel undergunned.

I only have one set of the Magpul MBUIS's, but they seem functional. They don't look like they'd take much abuse, but I try not to abuse my guns anyhow. I don't like them as much as my Yankee Hill fronts and MI lo pro rears, though.

I'm not saying that plastic is all bad...just these particular sights. Buy what you want to fit your needs. They don't work for me as I am able to break them easily. Aluminum can be broken under the right conditions too, as can the chrome lining in your barrel, etc.... Key word here:"EASILY"

I question putting the MBUS on the front sight due to heat....I haven't heard anything so far, so must not be an issue. Magpul makes some pretty tough stuff, I know their stocks take a beating so I imagine these things are pretty tough. I still like the metal BUIS myself though[Beer]
need to get me a pair of troys.

Magpul specifically states to not use it on a gas block rail. It is OK to use it on a hand guard rail though.

I am also probably going to get a set of Troy sights.

I just saw that on their site. It would suck very very badly to be shooting and the next thing you know you see you MBUS oozing all over your barrel[Bang]

With all of the hostility in this thread... I had a question but I am afraid to ask.


I am actually looking for a set of sights
I looked at some troys... I just cannot see spending ~3x what my upper costs for a sight.
For that I could get a decent Holo or dot.

But I am open for recommendations under $100
Rear sight only at this time.

I'm fond of Troys but GG&G makes good stuff. Here's one I saw on Midway that might work for you.

I almost went with another Troy on one of AR's but decided to give the mbus on the rear a shot. Ive played with it quite a bit and only used 300rds with it; so far so good. It's currently being used with a std. fsp and an M3 so I'm not too worried about having the greatest buis money can buy.

Nothings wrong with the MBUS. Some people just can't bring themselves to trust "Tupperware". Like any other BUS sight, they're there when your main Optic takes a dump, and should be used only then. Anything else get real Irons,... or a ACOG :)

I just received my front and rear MagPul MBUS on my rifle and they seem to be very sturdy sights. They do not flex easily, I like the quick flip-up design where you just press a button and they're up. The front sight post seems to be installed a bit high, though I haven't gotten to shoot with them yet so I can't say for sure.

I do like the rear option of the small aperture or flip that forward and a larger aperture appears, though I assume the smaller is for longer range shots and the larger is for closer range, the directions that come with the MBUS do not say either way.

ahem... as I remember it from Basic, Small is for Day, Large is for "low level light"


Ohh, and I went with the Troy rear sight in FDE from :

That does make sense, thanks! Now, I have to figure out how a makeshift tool to adjust the front sight post so when I go to the range (hopefully this weekend) I can get them sited in a bit.

This was my rational when I picked up a rear MBUS. I actually had my EOTech take a dump at a match (long story) and the MBUS worked great, even out to 200 yards. I did not want to dump 300+ on back up sights that rarely, if ever, get used.

I had a pair of them on my AR and they worked just fine. I switched to Troy BUIS only because I have a piston upper and the gas block gets hot and I dont trust having my front sight on the hand guard.

Getting out of a vehicle, doing transitions and moving with the sights up, gun getting kicked around when being a role player with simunitions,....I thank that was all of them. I'm rough on gear...if it can't handle being out of the safe, then I don't want it.
