Not correct. stock is not meant for ar15. causes feed problems. explained below. - Maxim Defense Industries CQB Gen 7 Stock For AR-15

Bought this back a few months ago to put on my duty rifle (AR15). Thank God I took it out after installing to train with the new system. Huge safety problem especially being in LE. This stock caused my AR to short stroke which causes multiple feed issues. It also caused my bolt to not lock back on the last round. These problems happened every other round. I would come to find out that this item is actually sent with a buffer and spring meant for pistol round (AR9/45) and not for a AR15 setups. I have since downed an additional $60 for the correct buffer and spring. Just be aware what you are buying before you commit.
