This item is the front sight and part of a second set of a like set of Magpul front & rear flip up sights, all installed on our AR15s & used as backup sights.

MBUS Front Flip-Up Back Up Sight Gen 2

by Philo, Verified Owner from GA, United States Written on August 26, 2026
I have previously used the Gen 2 and works great. HOWEVER, FIRST I ordered a Gen 3...mistake, the "tooless adjustment wheel" on the 3 is clunky at best, do not get the 3 in my opinion. I def prefer this 2 with the tool to adjust. Reccommend for back up.
Pros:
  • Better than Gen 3
Cons:
  • None
Best Used for:
  • back up if using optic that could fail
Would recommend: Yes

MBUS GEN2 Front flip up

by Philo, Verified Owner from GA, United States Written on July 31, 2026
I highly recommend the GEN 2 filp up for only use or as a back up to an optic. Get this Gen 2, NOT the Gen 3! This sight comes with a little adjutment tool works great and the sight is great. However! The gen 3 is adjust with a turn knob,,,clunky at best and while adjusting the sight post FELL OUT! I ltterally just chaulked it up as a loss and immediaty ordered the GEN 2.
Pros:
  • Easy consistant operation and adjusting
Cons:
  • None
Best Used for:
  • Back up to an optic
Would recommend: Yes

As usual, great product

by Tucker, Verified Owner from GA, United States Written on April 28, 2026
These magpul irons have always been my go to. they are slim, fold down out of the way and are nice and sturdy. i wish they had the black ones in stock, but that’s not anyone’s fault. i settled for grey and i actually really like them!
