The Minis are pretty good for what they are .. I've got the AC556 type weapons, and in Semi auto mode, they're VERY accurate in my opinion. in 3 shot burst, it's a little more difficult to control muzzle rise, due to the light weight barrel. In full auto, it's more like spray and pray. I would say, that if you see one, grab a Ruger GB20 (the semi auto version of the AC556) it has the M16 style flash hider and Bayo lug.. VERY desirable in either blue or stanless..The rifle looks like a minuture M14...The 7.62X39 is a great deer or medium Game rifle. The Garand style bolt and action is battle tested, plust the cartridge is good for hunting and also personal protection when need be.. Just my own opinions though
As for retail sales of Mini 14's....they DO find a home, but mainly when it's a particular shooter that's looking for exactly that type of Ruger. They are a bit pricey for Rugers.
