    Adams Arms 100-026-181 Ar-15 Standard Picatinny Piston Kits
    Item#:
    100-026-181  
    Our Price:
    $197.99
    Description:
    The Adams Arms Standard Picatinny Piston Kit converts a standard AR-15 direct gas impingement system into a cooler and cleaner running, short stroke gas piston system. By installing a piston system on your AR-15, it prevents harmful gas and debris from being blown back in the chamber, resulting in less fouling, reduced wear on the action, and it helps take the punch out of felt recoil. As an added benefit, the Adams Arms Standard Picatinny Piston Kit dramatically reduces muzzle flash and that super-sonic crack common to AR’s, ensuring optimum performance with night vision devices and suppressors. Three adjustable gas settings can be set for normal fire, firing with a suppressor Mfg: Adams Arms
