Hey Schnugg,
You done stole it. That's a great price. Those mags are a nuisance to find, too; you did well to get that many. I owned a Mini-14 for a good while, and I kinda miss it. First off, how's the length of pull for you? Mine always felt short. I picked up a 1" recoil pad designed to fit it, and it helped. I took it off when I sold it, and it's laying around. Yours if you want it. Next, I couldn't get into the sights. There aren't many aftermarket options, either. Having those scope rings will help out; a fixed 4x would be great on there. I worked up a pretty good handload for it, so if you're a reloader, I've got some data to share. It's gonna be 100% reliable. That's what Mini's do best, bar none. A good load will get 2 MOA to start, and closer to 3 when it's hot.
If you haven't been there, go to
PerfectUnion's Mini page; it's a subforum dedicated to accurizing the Mini 14 and 30. There are some great ideas in there, and more info than you'd care to read in one sitting.
Good luck, I think you're gonna like it!
