Most Helpful Positive Review Not for use on Gasblocks
This is a very well designed and built back up sight. It tucks down flat and pops up when needed. I did not realize it should not be used on a gas b...

Good to Go (GTG)

by Hank, from United States, HI Written on April 9, 2015
The Magpul MBUS front Sight is good enough to meet my basic requirement. The post is equivalent to the front iron post of a standard United States Army M4. The body of the sight however is a little to wide for my taste when aiming at a targets at a long distance (200m+). I moved this sight from my long gun to my SBR. Perfect....

Adjusts easily and sturdy

by spencer4hire, from United States, CA Written on March 30, 2015
Took it out to the rifle range and with the provided tool we made some quick, easy adjustments to zero in on target. Also easy to mount and flip-up feels sturdy. Optics customer service was helpful when I needed to cancel out of stock part but still honored free shipping ....
Pros:
  • Sturdy, Easy to install and zero
Cons:
  • competitively priced

Good Sight

by TR, from United States, IA Written on March 29, 2015
I put this and the rear Magpul MBUS sight on an AR pistol that I had built and it works great. They only needed slight adjusting and were dead on. I would purchase these sights again if I decide to build another AR in the future.....

Magpul front sight

by madmac, from United States, WV Written on February 26, 2015
The Magpul MBUS front flip up sight is an excellent addition for an M4 platform. The sight is easy to install and easy to zero as Magpul includes a sight adjustment tool with the from sight. The sight easily folds down so as not to interfere with my optics, however pops right into place with perfect alignment every time and no loss of zero. Excellent product!...

Great choice

by MB, from United States, CA Written on February 18, 2015
I like the Magpul MBUS front sight because it functions flawlessly and is very economical. Its design is efficient and its size is not too large. I prefer the non-metallic material because of its elasticity....

Well made...

by kingspawn, from United States, OH Written on January 27, 2015
This sight works perfectly on on a front rail that is the same height as the back rail. Although I haven't given it the "hammer" test, it appears to be constructed with a very substantial high grade of plastic. It works thru the optics of my EO-tech reflex sight. Much easier than using offset sights....

Good product

by OutEast, from United States, MD Written on January 12, 2015
Functional for light use (range days/limited volume shooting and easy handling). Definite weight savings and decent asthetics but BUIS preferred for hash environments/critical applications. Easy to adjust, install and remove....

Couldn't Ask For More

by Dallas Stewart, from United States, CA Written on November 15, 2014
Like it says, i couldn't really ask for more for the money. Bought it in FDE and matched the rest of my furniture perfectly. Easy to install, fits great and feels like it was built to last. Being made of plastic made me pause at first,not to worry, this thing is sturdy! Would gladly buy another or recommend to anyone looking for a good, cheap, back up sight....
Pros:
  • Cheap
  • Sturdy

Works perfect

by Nickname, from United States, CA Written on October 6, 2014
Sight works great as a back up or primary one. Installed it on my AR-10 and worked perfectly after it's first day at the range. Love the way it flips up for fast use when needed but lays flat against the rail for mobility when using my scope. Always excellent service from Opticsplanet....
