I used a bushmaster marked for hunting deer when on unknown land. Had to pin it to 5 but never had a problem a friend uses a old colt marked and swears by it.

Ana a thermold works good aslong as pinned to 5 or 10 as well

I use an old 20 that I cut off short for 5 rounds and then tig welded a new baseplate on.

I have a bunch of MagPull 30 rnd ers that I could pin but I'd really like to get a short one for hunting purposes.

i took a 20 rd Pmag and made a plywood block that fits inside the spring and limits the round count to 10.

works as intended and functions 100%
