Hello all, first post for me here. I bought a used stainless 188 series mini 14 a few months ago. I've had a few before but I always found something else I liked better and traded them off. Anyway, I decided that this is going to be my home defense/shtf rifle. It will be hung on the gun rack beside the front door. This rifle has been used and has some character but it's not been abused. I think it was a prison trade in or something like that. I took it out to shoot it after I got it and accuracy was not that good. I knew this coming into it so it wasn't a surprise or a deal breaker. My first modification was a Accustrut and it cut my groupings in half so on the heels of that success I decided I would tinker some with the gas system. I ordered and received a four bushing set from Accuracy Systems and installed the .040 bushing for starters. With factory .223 ammo it is 100% reliable. With my fairly light reloads (23 grains of Varget and 55 grain hornady soft points it's about 75% reliable. Since this isn't by any means a target rifle I just decided to use factory ammo. I have about 7 AR's in my collection but I just like the mini for my go to gun. Anybody else do any tinkering with the gas bushings? What worked or didn't for you? Mine now throws brass about ten feet. It was slinging them 50+ feet, dinging the side of the brass and caving in the case mout to the point I had to round the mouth back out before running the brass through the sizing/decaping die. I think I'm also going to load some hotter ammo using Varget and see what I get. If anyone has any comments on this post I would be happy to hear what you have to say! Thanks for listening!
