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 this work on an Anderson AR 15 5.56 Rifle With 16" Barrel AM15-BR as purchased?
Dave T on Dec 4, 2018
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.
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.
Fit on EQ-12 Gen2 Quad Rail from Aero?
C A B on Aug 3, 2018
BEST ANSWER: These will fit any standard 1913 rail.
Will this fit on the freedom rifle?
Davie L on May 18, 2019
BEST ANSWER: Should fit on any picatinny rail. Though, I would not recommend these sights because the pivot pin will walk out when not in use. Essentially you will not have sights when you go to use them.

Ant1985 on Apr 8, 2019
BEST ANSWER: Absolutely! They work perfectly!
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.

Massive let down Magpul
Not reliable as the pivot pin walks out of the sights. Pathetic engineering with no sort of physical retainer. If you want sights to let you down by not even being on the gun when you need them buy these. Otherwise save the money and get something better. I would give zero stars but I can’t. Please do not use these if you ever think you might have to rely on them.

The polymer sights look like they will hold up to lots of use. Easy to sight in, especially since the front sight tool is included.

AMAZING DEAL! ACCURATE, EASY TO ZERO & MAKE ADJUSTMENTS. GREAT SIGHTS.....
Buy the Magpul BUIS’ when they go on sale, especially with “free shipping!” No one can touch PSA’s price when they’re on sale. It’s a PHENOMENAL DEAL!!! Absolutely great, reliable sights. Accurate, easy adjustment, mounts perfectly to any 1913 Rail, comes with front post adjustment tool, easy to zero in, and easily, one of the most lightweight set of back-up’s on the market! There’s honestly no negative comment or issues in regards to the Sights to mention (I did look to be fair). They function perfectly and I’ve had NO issues or problems with them. This is my fourth set of Magpul BUIS’ I’ve purchased! They function perfectly on my $3000 LMT or my son’s $550 S&W M&P 15. I Highly Recommend. Happy Shooting ;)
