So a CZ 7.62x39 conversion will have a shorter Grendel cartridge length than the AR based 2.26"?
Here is a comment from the SAVAGE forum regarding Savage 10 FCM 7.62x39mm Scout rifle magazine length:
"The FCM is set up for a standard short action detachable mag. The 7.62x39 mag that comes with it has an overall internal mag length (because of a spacer that Savage puts in the rear) of approximately 2.46 inches.
You could easily replace that mag body, spring & follower with a .223 mag body, spring & follower or a standard short action .308-family mag body, spring & follower if you so desired."
It appears to me that the Savage option is more attractive since it will allow for longer cartridges than allowed in the AR platform.
The 10 FCM is a AccuStock platform...if I go this route, I'll probably keep the factory stock and see how it shoots with a Pac-Nor barrel in Grendel Match. I think the 2.46" magazine would be plenty, so no need to switch to .308 magazine (and have to modify it for Grendel).
