I spent two years trying to accurize a Mini-14 and I think I finally did it for 89 cents and a little work.

I'll bet a few folks would like to hear more about your miracle Mini-14 cure. I know I sure would.

There are two problems with a Mini-14.
The first problem is that the 10-32 screws on the gas block are too large for the application. It's actually possible to squeeze the barrel if the screws are too tight. I proved that by using the correct machinist's inspector's plug and ran it down the barrel where it stuck at the block.
When the screws are loosened, retorqed, and locktited, the groups shrink from 8 inch groups at 50 yards with a cold barrel to a three inch group at one hundred. That solution took an afternoon of work. Factory torqued rifles don't have this problem.

The next and last problem that the Mini-14 has, is that the barrel changes point of impact as it gets hotter. This is the problem that has been taking two years. Teacher317 was kind enough to look over my article that I'm trying to submit to a magazine. I still have to wait for cooler weather so I can start with a cold barrel and then progress to a hot barrel and see if the POI changed. It wouldn't do any good to tell what I did since I haven't proved it yet.

By the way, I was treated the same way as some of the posters are treating this inventor. Half the owners wouldn't believe there was anything wrong with their charming little rifle and the non-owners told me I was wasting my time working with the piece of %$&*.
