Never have shot and probably never will purchase a newer model Mini14 . 'BUT' I don't hate Mini14's . I still have one in the safe, plus have had several of them, enough to know the negatives to fix . My keeper in the safe . did little bit of Trigger group work, I cut barrel down to 16" with moving back and re-pinned the front sight blade, threaded the Muzzle and added a FH . Lathed a new gas bushing with smaller gas port hole, and added front and read recoil buffers to the OP Rod system . all who shoot it say that it the smoothest Mini14 they ever fired . and with hand loads it is about 2-MOA average group size @ 100 yard .
It's just that the biggest inherent flaw you are unable to fix, other than Hideous Ruger Trigger pull, and with it's using only proprietary Ruger Magazines . is the unchangeable main design & that's the OP Rod gas system that slamming back and forth adding stress for barrels accuracy . They all come from Ruger ( especially all the older models ) ' Rudely' and abusively way over gassed . Abusive to the rifle itself and abusive to all shooters sitting 6 or 8 benches down to the right of you getting hit with your Brass . . So.. cutting down the amount of needed operating Gas and the recoil buffers both front and rear are a must .
The biggest Positive the mini14 has is, that it is designed a short OAL rifle . It a nice lightweight little packing rifle . Also ( my opinion ) it pretty [beeep] reliable and that it will eat and extract anything you feed it for ammo, and that makes it a blast to shoot . It will never be half as accurate as your low-end retail AR15, but it runs cleaner than Impingement that barfs dirty gas back into the Receiver, So that make it fun and easy maintenance also . Just run it hard and then spray a little break free on the bolt and put it away .
