I don't know much about either gun.
I do own a mini-14, one of the newer series, in .223
It has a synthetic stock, and a stainless receiver and barrrel.
I have a scope on it.
This gun shoots about 4 inch groups, whith what little I have shot it.
I bought a couple of hi-capacity rounds for it, neither worked well.
I have since learned you almost HAVE to use factory magazines
I don't like the magazine release. If you are using the 5 round magazine it came with, the magazine release is in a perfect location to accidentally press it.
Still, the mini14 has a very loyal following, which would not exist if this were a piece of crap.
Is the AR15 any better as a factory rifle.
I take a hand to hand combat course, the instructor is fond of the M4's, if I heard him right S&W makes a good M4, but that was discussing select fire weapons.
I'm trying to decide whether to keep the 14, or get rid of it before I put any more money into it, and go with an AR15 type.
