Hi everyone.
After 20 years away from the military, I decided to pick up shooting again, primarily focused on marksmanship/targeting.
Picked up a CMMG Mk3 (new) 18" SST barrel about 4 weeks ago and so far it's been working like clockwork, and I've since put in over 200 rounds with zero jams/FTE/FTF etc. It wasn't completely smooth sailing out of the box though. They had installed an incorrect bolt catch but CMMG quickly remedied the situation by sending me a replacement bolt catch, no questions asked.
I found some problems with ProMag steel mags where the bolt would catch on the plastic follower with the last round in the mag. That was easily resolved by putting in a bead of hot glue on the follower to better seat the last round. Magpul 20LR pmags work flawlessly but are impossible to find these days.
At the range, I'm averaging 0.8"-1" groupings (5 rounds) but that figure goes up and down depending on how "tired" I am. Guess I'll need a lot more practice to get back to my old form.... maybe I'm just getting too old....LOL.
I do own/run a CNC machine shop and it's likely I'll be making parts for it sooner or later....
Here's the baby.
....and the baby now:
