everyone !
i have tried to find the specifics of every piston operating systems of every AR-15/M4 design and the only one i can find the specs on is this one,
not a very good view, but this design is in my
OPINION one of the best piston systems yet !
all these piston makers that advertise in gun magazines tout their system but very few show their specific design, even when i go to their web site they do not show it specific parts LWRCI has a slide show of how theirs work.
