Adams Arms AR15 Gas Piston Rifle. Agency Base Rifle. All of what you expect from the AR15 plus the benefit of Gas Piston reliability and less maintenance. 

In 1957 Eugene Stoner developed the AR15/M16 rifle that shoots the .223 Remington/5.56 NATO caliber rounds. The design of this rifle utilizes the gases that push the bullet down the barrel to cycle the action of the semi-automatic and full-automatic AR15/M16 rifle. These gases are vented into a gas tube through a hole on the barrel (the gas port). The gases travel back toward the receiver of the firearm and use its pressure to push the bolt carrier backwards toward the stock of the rifle. This utilization of gases to cycle a firearm's action is known as Direct Impingement. It is the biggest flaw and concern with the AR15/M16. Because these gases are released into the receiver, a layer of carbon and burnt gases coat all the moving part of the firearm. This also leaves a lot of heat inside the receiver causing undue stress and wear on many critical parts. The Gas Piston operating system help eliminate this issue by venting the dirty gases and keeping the gun cooler similar to the AK47 operating system .
