Quote History Quoted:
MK2s are the successive generation.
You can run a can without concern.
Can't speak to the Gen 3 Pmag issue, but why worry? You can find a ton of the older Gen 2s which run flawlessly and are available at discount.

No... This is incorrect.
The Mk2XX is the large frame, .308 version. They come in both Mod0 (non-free floated, fixed gas block) and Mod1 (free floated, adjustable gas block).
I believe the reference to operating suppressed to that you need the adjustable gas block on the current spec, Mod1 version. If you're looking at a Mk220 (which means a 20" barrel) then it's a Mod1 as the Mod0's only offered a 16" as the longest barrel.
I can't speak to the PMag issue as I've only ever run the original .308 Pmags in mine (a Mk216, Mod0).
