LIMITED QUANTITY - WHILE SUPPLIES LAST - ADAMS BUILT FOR HULDRA WITH ADAMS LIFETIME WARRANTY - AVAILABLE PINNED TO 16" TO BUILD NON SBR.
The 5.45 MIDLENGTH BASE 14.5" Upper is a short barreled upper that incorporates the patented Adams Arms technology and the drop in mid-length gas system with railed Adams Gas Block. 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. With the patented Adams Arms piston system, you'll have an upper that will run cleaner, cooler, and longer than any other AR upper you own.
