Factory bcm 12.5” upper with bcg and ch. Very light weight and shoots like it should just have too many blackouts now. Want to sell to get a suppressor but may trade it with its lower for a nice glock with x300 and optic or upper for a 16” 5.56 upper (or 13.7”-14.5” p&w). Text me 9037245344. I’m in Elkhart
