POF-USA's solution to timing problems related to AR-15's with short gas tubes, POF-USA developed precise op-rod/piston geometry and regulated gas pressure to enable rifles and carbines to be properly timed and bolt ...

Firearms with a direct impingement design can, in principle, be constructed lighter than piston-operated designs. Because high-pressure gas acts directly upon the bolt and carrier in a direct impingement system, it does not need a separate gas cylinder, piston, and operating rod assembly of a conventional piston-operated system, only requiring a gas tube to channel gas from the barrel back ...
