Troy makes a pump action AR upper.
Bolt style, I'd just buy a bolt action only, and a chassis if you want the features/options of the AR15.
That was me. The HUGE problem was easily solved with a foot long 2X4.
This showed up with factory loads only.
Starting loads for the Grendel were ejected easily.
The problem is the AR platforms have no primary extraction when operated in a manual mode.
I am considering having a custom made Grendel barrel for a Savage receiver. That way I could go as heavy as I want.
