I originally purchase this rifle brand new from my local gun store. It is a DPMS A15 carbine. It was an a2 style rifle. Recently i decided i wanted to change some stuff so here is what i did. I got a CMMG mil spec a3 flat top, a UTG free float quad rail, troy industries muzzle brake, MFI riser CAA front grip and light mount, scorpion tac light, and a crappy BSA red dot that will soon be replaced. The gun is amazing it has never let me down in the 3 years i have had it,and with the new stuff done i hope to continue. I know it dosent compare with some of the AR's others have on the forum but it is what i can do with mine at the moment. Comments and questions are vary welcome. Please let me know what you guys think. Sorry for the clutter in the first pic it is the only pic i have on the gun before the mods.
