as green gas is propane, as I stated thats for sure, it just shoots to fast during rapid fire to lock after empty, ususaly after u stop fire, then pull once, it will lock, otherwise, theres a 5/10 chance of it locking during a good fire fight lol. Know from experience.
BTW, metal slides lock better and usualy alot more than reg, but ive had mine skip a lock back once or twice.
