Description of the Rifle and its New Piston System Patented Ambidextrous Non-Reciprocating Forward Charging Handle/Forward Assist The ADCOR A-556 ELITE TM has a gas-driven piston incorporated into the top rail, replacing the standard gas impingement design. The piston drive ensures reliability by preventing hot gases and carbon particulates from entering the receiver.
Patented Ejection Port Dust Wiper System Patented Rail System Spring loaded dust wiper The ADCOR A-556 ELITE TM rifle has a spring-loaded dust wiper mounted on the rifle’s bolt carrier to prevent dust, sand and debris from entering the rifle.The dust wiper assembly has two springs between the bolt carrier and the wiper to continuously push outward away from the bolt carrier. This allows the dust wiper to continually engage the inner surface of the receiver when cycling.
4-Position Regulator Utilized for different types of ammunition and suppressed fire to maintain proper cyclic rates. Regulator instructions Regulator shown with position 2 selected 1.
