ADAMS ARMS

Adams Arms is a firearms manufacturer based in Brooksville, Florida. We have spent over two decades working to improve the standard direct impingement AR15, by making it cleaner, cooler, and more reliable. The Adams Arms Retro-Fit Piston Drive System uses the same gas port on the barrel to work the action of our inverted piston. Instead of directing the gases into the receiver, they go into a gas plug and drive rod sleeve invented by Adams Arms. The gases are contained inside the drive rod sleeve and push the bolt carrier rearward using the gas pressure to cycle the action.
