Been having some random extraction issues with my MK3.
It runs fine with the steel DPMS mags, but I end up having jams when using Pmags.
When I say jams, I mean the fired casing and the new round both getting stuck in the receiver.
I'm just wondering if anyone has found a similar issue and how they solved it.
Also wondering if the extractor upgrades for a 5.56 bolt (spring & o-ring) would work on a .308.
