I got a colt 9mm smg upper and it came with the 2 pieces that are pinned into the mag. Would yall go with a dedicated lower or get a magwell conversion block? Price is about the same. Who makes the lowers that have the holes for the blocks? TIA

Nobody that I am aware of.......

If you are starting from scratch. I would buy a lower, get a dedicated Hahn block that drops in from the top (you need to remove the bolt hold open, then put the block in, then replace the bolt hold open.) and call it good. Dedicate that complete lower to your new 9mm build.

just my $0.02
