so, after a long build time it is finally complete. it started life as a Stag Arms 2L. i replaced the barrel with a 14.5" DPMS 1-7 twist. the front gas block/flip-up sight is a YHM clamp on. the free float tube is YHM. the rear sight is YHM. the optic is a TA31RCO-M4 ACOG. stock is Magpul UBR. Mappul MIAD grip. KAC ambi mag release. Surefire MB556K muzzle brake. Surefire MINI suppressor. and for the Coup De Gras i used my 07 FFL to convert it to 3 round burst via a form 2. i think it worked out pretty well. the only other change i might make is a 10.5" barrel in the future but overall i am extremely happy with it. it weighs 10.8 lbs fully loaded and is 36.5" overall with suppressor and stock extended. hope you enjoy.
