Know also that blowback carbines as a rule like hotter ammo. Q4318 NATO works fine; 115 white box may or may not; 147s are problematic.

Re: mini 14. I had one for years as a car gun, sold it recently to buy a 6920. Problems: 1. Lack of accuracy. 2. The only mags that work are factory 20 round ones. 3. If you need a part, you must go back to Ruger. 4. Optics mounting. Why would anybody mess with a mini when you can get a M&P Sport AR for $499, and a spec grade AR for < $1000?
