Great GG&G Product


GG&G products are a personal favorite, and end up on most of my builds. Primary Arms is my "go-to" retailer for almost all of my firearm needs...Excellent technical assistance and FAST shipping!

good piece


I like the bigger aperture for both eyes open shooting techniques. Doesn't have an elevation adjustment. With the front gas block sight from GG&G and a level it only need 2 clicks to be zeroed at 50 yards. Solid in the up position and easily deployed from the down position.

Awesome Sights


These are rock solid sights, there's positive engagement when sight are deployed, no slop or wiggle at all in the up or down position. I like that the mounting screw is an allen head and not a slot head (less chance of buggering up the screw head) and that the mounting clamp runs the full length of the sight body not like other sights that use a tiny little clamp. Well made sight.



when I got the site it was very nicely packed in a box I opened it up and do my amazement this site is extremely robust I was kind of scared but it was going to be flimsy but like I said to my amazement it was extremely robust very easy to install and site in
