Only this one left TRADED
Marked Caliber - Multi so you can build any rifle you want - 22, 40, 9mm, 5.56, etc.
Has upper/lower adjustment screw to eliminate play and hex bolt keeping the rear takedown pin spring in place - so if you take the stock off it does not fly out and get lost.
Nice pictograms like H&K lowers.
Complete with milspec extension tube and Colt M4 stock.
