Sun Devil Manufacturing 2011 AR Lowers Posted February 4, 2011 in AR-15, Rifles by Steve Johnson with 9 CommentsTags: 2011, ar, ar-15, rifle, rifles, shot, shot11 Sun Devil Manufacturing has two new billet-CNC’ed lowers for 2011. The one is for DPMS-compatible (.308) rifles and the other for standard AR-15 rifles. They both feature integral trigger guards. Sun Devil lowers. I love the tan-colored lowers without the forward assist. I do not have pricing information.
