K.I.S.S.

This was the perfect rear site to pair up with my M4 front site. This is a no-frills budget minded A.R. 15 build. A bare-bones A.R. 15 with no magnifying optics, scopes, red dots, lasers or any of the other Lego gadgets that are available. I had to pull the set, screw completely out and then use a rubber mallet to tap the site onto the Picatinny rail. You will probably have to do this too. It was a tight fit. Again for the money it’s hard to beat.

Yes, I recommend this product.

Tought to Get on, but Solid

6 months ago
Had to beat the heck out of this thing to get it on, but once it was on, it'll probably never be removed anyways. It's reliable and perfect height though so I can't complain.

Yes, I recommend this product.
