I recently got a couple 300blk Pmags and was wondering if they'd reliably feed 223/556 in my 223/556 ARs. Anyone ever try?

Try them out and report back.

Tried it out, ran 30rds 55gr Wolf Gold through my 10.5" SBR with no problems.

They've always worked perfectly for me. If they weren't marked up arbitrarily, all my PMAGs would be the .300 BLK variant because it only expands their functionality with no downsides (unless you REALLY like different colors and/or windows).
