Magpul Gen 2 MBUS Front Back-Up Sight - MAG247

 

Model: MBUS – Front Gen 2 
Weight, w/ hardware: 1.2 oz. 
Height above rail, stowed: ~ 0.51 in. 
Length, stowed: 2.6 in. 
Length, deployed: 1.5 in.

The MBUS (Magpul® Back-Up Sight) is a low-cost, color injection molded, folding back-up sight. The MBUS Front Sight is adjustable for elevation and fits most 1913 Picatinny-railed hand guards, but is specifically tailored to the AR15/M16 platform.

Features:

•Impact resistant polymer construction provides light weight and resists operational abuse

•Spring-loaded flip up sight easily activated from either side or by pressing the top

•Detent and spring pressure keeps sight erect but allows for unobstructed folding under impact, etc.

•Clamps to most any MIL-STD-1913 Picatinny/STANAG 4694 railed hand guard and provides the same height-over-bore as standard A2 irons

•Protective wings shield the spring-locking A2 front sight post

•Elevation adjustment tool included, but most aftermarket A2 front sight adjustment tools may be used as well

NOTE: Cannot be mounted to a railed gas block due to excess heat issues. Front MBUS must be mounted to a railed fore end on the same plane as the receiver rail. Because of this the sight is also not compatible with MOE Hand Guards.

Will these work on my just bought PSA Gen2 PA10 18
SKU # 503654?
Robert K on Jun 2, 2019
BEST ANSWER: Magpul BUIS are the best. Ideally they are designed for smaller, fast and light calibers, but of course, for the PA10 calibers, at short rifle ranges they are fine. They will work on any rifle where the front and rear mounting platforms are on the same plane.

will this work on an Anderson AR 15 5.56 Rifle With 16" Barrel AM15-BR as purchased?

BEST ANSWER: The AM15-BR only has a gas block rail to mount the optic and I wouldn't put a polymer sight on it since it will likely melt. This set works best on a free float handguard.

will these work with holosun micro dot?
troy m on Feb 13, 2019
BEST ANSWER: As long as you get one with the "1/3 Co-witness mount" in my opinion. It will work, but I have not had a holosun to try, but I have used these sites with many of the budget-friendly red dots. you just have to be sure it has 1/3 co-witness and go from there.
I have a 9 slot picitanny rail and vortex-sparc-ar-1x-red-dot-scope will these sights work well and fit all correctly on my ar pistol set up?
Davidg on Jan 6, 2019
BEST ANSWER: They will. I have them behind a Romeo 4 and Juliet 4, and there is still space for them (rear stays down when Juliet is up).
If I were to get these in another color (like fde), would dying them affect the flipping mechanism?
Jocular on Sep 26, 2018
BEST ANSWER: It’s hard to say. The sights are fairly tolerant to heat considering how hot an aluminum picattiny rail can get under rapid fire. However, fully submerging the sights into really hot water with dye may cause warping in some places, especially where the springs have tension.

I have been using these for years. For the quality and price Palmetto sells these for, why would you use anything else?

Magpul sight set

They are worth the money, better than most cheap red dot optics I've tried. They remain on target once installed and adjusted.
Got these back up sights recently because I've built too many AR 15s and can't afford the fancy optics. They are ruggedly constructed, mount securely and are actually better than the standard issue A-2 sights.

Functions as expected.
Fit and finish is great. No problem mounting either site to my Ar. Solid connections. I would not hesitate to recommend these. I use them in case of a mishap with my red dot. Price and shipping is always great with PSA.

Basic working MBUS
They do what they need to do. Magpul makes decent working products at great prices. ~50$ after discount code. A must for most builds.

Affordable, Reliable Backups
I've used these as backups on several rifles. While they don't see as much use as whatever primary optic I have setup, I always zero them and check them after a few hundred rounds. They hold zero just fine.

Disappointed!!!
I'm very disappointed in these sights. They won't fit any of my Ar pistols or rifles. They are not wide enough to fit onto the rail
