Most Helpful Positive Review BUIS is a must have!
Used one when I was in the Marines. Wellnever used it till i bought one for my own rifle. Its difficult to use when you use an EOTECH. But its great and you dont have to necessarily holdover for basic irons. Dial your range and you will be generaly on target. Its a great sight.

Attention Iron Sight Fans

by Rebel Yell, from MO, United States Written on February 13, 2024
This has to be the best rear peep sight I've ever purchased. I realize there are are a lot of you who depend on scopes and such, but I advise that you have backup iron sights for your AR type platforms just in case. This particular rear peep is dead on from 100-600 yards and is quality made and still leaves me room to add my scope if I wish. Your not going to be disappointed with this attachment.
Pros:
  • Price and accuracy
Cons:
  • none for me
Best Used for:
  • close and long range shooting
Would recommend: Yes

Great iron sight!

by UTG35, Verified Owner from AL, United States Written on February 4, 2024
I bought this to train with my AR-15 for A4 post and rear sight use. We have this sight on M4’s that we shoot with for competitions in the Army guard. My only complaint is the sight picture at 100 yards is super small. It’s just how it works though.
Pros:
  • None
Cons:
  • Small sight picture
Would recommend: Yes

Matech is Gucci

by Josh, Verified Owner from KS, United States Written on October 25, 2022
This rear sight is super gucci is you throw it on a Colt monolithic upper for a gnarly throwback vibe. The ole boy is crisp on the adjustments and slaps hard. Very easy to sight in and seems to hold zero swell.

This sight is made for ARs with FSP!

by max, Verified Owner from VT, United States Written on September 29, 2022
Please by this if your AR has a FSP. There are many other to buy but this and the KAC rear sights are specifically made for a FSP. If your here from ebay seeing all those deals just buy it from here you know its legit and its brand new. I was in the same boat. Ask any vet that has used a m4/m16A4 varient they will sear buy it i know i will. Cant go wrong also. The "my screw latch broke from tightening it". Well probably over did it. Like anything mechanical read the directions PLEASE! Yes they sell replacement parts not sure if they do on OP but read the directions and youll be just fine.

FANTASTIC BUIS OLDSCHOOL SOLID WELL MADE. WILL LAST YOU

by Andyman, Verified Owner from CA, United States Written on November 7, 2021
This BUIS was issued for the M4 as a rear iron sight. Man tbey are solid, massive. The great thing these sight have over others is that it allows your eye a better peripheral view. Sight is thin allows you to nagviate your eyes much quicker. The Army sure made me believer on these iron sight.
