That must take lots of rounds. My Mini 14 was built in '90 and used about a thousand rounds since I bought it in Feb '08.
But it will shoot more reliably than some AKs. All of my ammo was Wolf or a little S. Bear, and it never had a single ftf etc. Zero.
Also, it never had a single mis-feed with a newer polymer 30-rd. Promag, despite the fact that it did not fit tightly.
My Mini was 100% reliable
, more than an AK with just forty rounds which I watched a buddy use.
Having two Minis, only sold it to justify buying my first "Jungle Carbine".
