NPAP: Single stack to Double Stack

[def90]

Depends if it has a double stack trunnion or not, most of these actually have a double stack trunnion. The bolt doesn't matter, a single stack bolt will work just fine. If it is a double stack trunnion a few minutes opening up the magwell is all that is needed. If it's a single stack trunnion a bit more work is required.

The ones done needed the double stack, as the s/stack had issues picking up rounds. YMMV
