Re: Pump action AR-15 rifle
If there is no spring pressure keeping it forward, it could easily rotate back. Not concerned about out of battery...I know that system...but forward force would be the only thing keeping it rotated in fully locked condition.
I once converted an M-1 carbine to a pump action. Worked great, but required a little help (forward pressure...just a little) keeping it in battery preparatory to firing. Seems the AR bolt, unsprung, would be the same. I may be remembering wrong...the operating rod of an M-1 carbine contains a spring.
Thinking about it, the manufacturer probably has some spring pressure built into the operating rod of the pump AR. Sorry for the confusion...Last edited by Bang; November 16th, 2017 at 04:55 PM.

Re: Pump action AR-15 rifle
Although I've never handled one, I'm sure that its much like a pump shotgun. locked in battery till you either fire it or depress some sort of slide release. I would hope the engineers thought of this, if not the Liability lawyers will after a few out of battery incidents and product recalls
***EDIT***
just looked at a You Tube vid, it does function exactly as a pump. There is a release for the slide at the bottom of the trigger guard just behind the mag well
Ive always thought Id like a Remington 7615 pump, but they are tough to find. if the street price is reasonable, I may give one a shot for shits and gigglesLast edited by SgtRecon; November 16th, 2017 at 06:05 PM.

Re: Pump action AR-15 rifle
on the AK par-1 and most other pump ar15 there is still a buffer and spring keeping the bolt in battery. (never handled the troy though)

Re: Pump action AR-15 rifle
So you're pumping against the buffer spring, making the pump an ersatz charging handle? Is the buffer spring driving the action back into battery (or near battery), or is it still necessary to actually push the pump to load the next round?
I must confess ignorance of the technology to this point.

Re: Pump action AR-15 rifle
The Troy version doesn't use a spring, it uses a bolt release that functions like say an 870 does. Push the button to unlock it and you cycle the action, obviously you don't need to push the button after it is fired.
This is the .308 version but the .223 version funtions the same.
