The Adams Arms team is committed to providing cutting edge technology that meets the real needs of the modern warrior. Adam Arms' Mid-Length Base AR-15 Gas Piston Upper Assembly is a standard MIL-SPEC AR-15 upper that incorporates patented Adams Arms technology with M4 style handguards.

The mid-length piston system provides a longer forearm, ergonomic grip and a longer sight radius between the front and the rear sight for quicker sight acquisition and less felt recoil. This AR-15 upper includes the patented Adams Arms piston system which allows the upper to run cleaner, cooler and longer; pinned and welded with a VDI Manimal Flash Hider. The piston system parts and the barrel have been treated with a salt nitride melonite process, making them harder and more corrosive resistant than hard chrome.
