I got the Sulun tac-12. I have completely stripped it, cleaned/inspected it and carried out some issues any proper CDO (OCD arranged in alphabetical order... You would have to be OCD to get that one) guy would do.
To be honest it wasn't anything more than a Remington or Mossberg.
The feed ramp was terrible. It was fixable with some grind/sanding. I almost burst a blood vessel in my eye removing the cocking handle. You have to turn with considerable force60 degrees and then pull if you don't already know. I took some time to soften these ridges and re profiling the part that inserts into the bolt. It's better but could still use a bit of work.
My most serious issue was the magazine cap. It would back off during the course of firing. To me that's a fail. I thought of sending it to be repaired but had this vision of an ex toothpaste salesman from Isle 6 at Rexall gluing something in place. Hey it's still Covid season so I took on a project. I planed of .060" with a file with precision exposing the ball so it would index into the detents on the magazine cap.
Whale oil beef hooked (Say it loud the next time you are in a check out line again and again till you get it) IT WORKED! 250 rounds and it hasn't backed off, DONE.
Challenger 7 1/2 target was the main ammunition used but there was a mix of #4 Federal, Kent, Winchester white box best use as a door stop ammo. The Sulun made it all go bang and spat out the hulls like a Redneck with chew. I had 1x failure to eject. I did have someone else shoot the thing that didn't cuddle hard enough. She had 3 stoppages back to back at the end of her session.
