EDEMO Adams Arms Piston Kit Standard Picatinny Block Pistol Length Standard BCG/.750 Gas Block/Drive Rod Black EDEMO3 Used Condition Fair. 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. Adams Arms proprietary operating systems mechanically actuate the bolt carrier external of the receiver. This keeps the internal receiver and all the critical moving parts clean and free from heat and carbon build up. Here are some of the main differences when using the Adams Arms Operating System: Short Stroke Free Floating Piston System Self Cleaning Carbon and gases are expelled forward away from the operator Bolt Carrier Group and other critical components remain cool and clean Corrosive resistant coating processes Harmonics are not transferred into the barrel Adjustable gas settings for various applications Doesn't vent direct to atmospheric pressure; this eliminates flash signature and supersonic crack which is optimal for night vision and suppressed fire Please note that the Receiving Bushing and Installation Dowell are no longer included.
