.308 16" discontinued length on mega arms maten receiver set pre zev. Everything else is noveske. This was painted but I removed the paint. There is left over paint on the barrel and top rail. Everything other than the buffer tube and stock is cerekoted in Magpul fde. This rifle is rare and is a tack driver. I achieve sub moa easily and sub 1/2 moa when I don't suck. It is missing one rail screw but has 5, it doesn't affect performance. Noveske sells a pack for $7 Can provide more pictures upon request. Magpul STR, Arken Ep5 available in other listings. Can include some 20rd duramags if we work it out.
