Adams Arms 14.5" Pinned Manimal 16" Piston Base Upper AR15 5.56
The 5.56 Midlength Base 14.5" AR-15 Upper is a standard mil-spec upper that incorporates the patented Adams Arms technology and the m4 style handguards. The midlength piston system will give you the benefits of a longer forearm by giving the user a longer, more ergonomic grip, a longer sight radius between the front and the rear sight for quicker sight acquisition and less felt recoil. The piston system parts and the barrel have been treated with our salt nitride Meloniting process making them harder and more corrosive resistant than hard chrome. Add the patented Adams Arms piston system and you'll have an upper that will run cleaner, cooler, and longer than any other AR upper you own. Pinned and welded with VDI Manimal Flash Hider to be legal 16" non-nfa length. COMPLETE UPPER WITH BCG AND CHARGING HANDLE.
