The details and technical specs are at my buddy Steve’s place at the Firearm Blog. This looks awesome, and is something that will probably get tested in the crucible of 3-gun competition. Actually, it wouldn’t surprise me if 3-gun competition was the genesis for this idea, since those guys are always looking for a way to carry more ammo in their rifles.

thats a very good idea thanks
I’ve got a feeling it’s geared more towards the Marine Corps IAR concept than just three gun. (of course three gunners will benefit greatly as well.)
