Hefty and Functional


Other than being a bit of a pain to screw in because of really tight thread locker (it is anchored in their though), I really like this thing. It's hefty, balances the gun better for me, has a sling loop or QD socket for for a sling, adjustable length of pull, and the comb height can be changed with extra accessories. I like the grip angle too. The price is right for this feature set for sure. Feels quality, as expected from Magpul. Buy it from Primary Arms and you won't be disappointed.
