What's the differ ? Dose the AR-15 work like this?
Once the bullet passes the gas block, the high pressure gases pressurize the cylinder pushing the piston and bolt carrier back, bolt unlocks, carrier continues to move backwards cocking the hammer and ejecting the empty case.
Is the CAR A4 a Carbine ? How dose is work ? I don't want to seem like a dumb $hit , but I really don't know ? Can you explain how ?
