Mine is Frankenpinned with a bad paint job to try and cover it.
I also made a small mod to mine to ensure only 5 rds are loaded from the stripper clips.
Otherwise a 6th rd can come off which you had to shake out and put back on the clip.
Drill and tap a hole for a set screw just under the follower lift area.
Might as well make it work right if I have to have it in there.
