Just finished my 9MM AR 15 build.
Rock River 9MM lower, Cmmg upper, Troy 13.8 rail, stage 1 trigger, 9mm buffer, Magpul Ambi safety, Magpul stock, Magpul over sized tripper guard, Ergo grip, A2 flash hider and Burris fastfire II. Went to the range last night. The red dot is about 6 inches to the left at 7 yards LOL Fired and performed well. Only issue was the 9MM buffer doesn't slide over the spring easy, so the bolt wouldn't go back to hold the bolt open after last round. Sanded and polished the buffer, works better but not perfect yet. Another issue was Brownells mag's will not always push the bolt release up enough to hold the bolt back after last round too. http://i1240.photobucket.com/albums/gg493/buyandsell1975usa/done_zpsc81b94ce.jpg |
