Hey Major & combat, thanks for the tips! I've got a big jar of Permatex and painted the threads.
I put about 300 rounds through it Friday and Sunday evening - used a CMMG conversion kit in my AR with BlackDawg mags and had no issues. I cracked the can loose internally and on the barrel after every 2 mags, and it was certainly feeling a bit gritty after the 4th mag.
Around 9:00 last night I had just put the can in the safe and put the standard bolt back the AR when I saw an opossum walking across my yard - I spotted the little turd messing with my garden a week ago, and lately something has been getting into the trash. I missed out on my chance last night but next time I will be ready!
EDITs: Shot CCI 1050fps, CCI 1070fps, Aguilla 60grn SSS. I put one high velocity round through the can and while it was still loud it was just the supersonic crack.
The CCI 710 won't cycle the conversion kit so I didn't bother with them. My bolt action Marlin is getting threaded and will be ultra quiet with the 710s and the Mite
This thing is a blast!
