I finally finished my Mini-14 this week, and found a little gratification at the range.
My gunsmith threaded the barrel after I recrowned it, and installed my Troy flash hider. He did an excellent job, indexing it without the need for shims or a crush washer. At the range, I didn't have any tools to re-zero my sights after putting it back together, so I just shot a couple of boxes through it at 25 yards to get an idea of how it would behave. First impressions are excellent. The hybrid porting on the flash hider did tame muzzle rise somewhat, and the short barrel, crown and flash hider have resulted in a consistent pattern with no signs of stringing shots as the barrel heats, or of flyers in the first round out of the magazine. Both were issues before. Group size is hard to assess with a red dot, so I'll revisit that at 100 yards with a scope later, but this target is very encouraging.
Four shots at 25y, slow fire, with a relatively cool barrel. This was after 6 shots that settled the action into the stock. I discounted those after a rim failure on one case interupted my first group.
This is the last ten rounds of 40, rapid fire (under 5 seconds) from a rest with the 2 moa red dot. The berrel was smoking after this group.
