AMT AutoMAG III in .30 carbine
I own one, bought it used. I would buy it again, for the purposes I bought it: fun, and to make people at the indoor range look at me funny when I get it out and shoot it. Trigger is a bit mushy, lots of takeup, but I got used to it. Sites are adjustable, but I had trouble getting shots close to the center of a B27 silhouette target, so I filed them until they were. Not much to file.
It will keep rounds well within the 9-ring of said B27 target at 25 yards. That would be 7" wide by 11" or so tall. It may be better, but I did not keep the target, I was just trying to get the group centered. I should try again, just for accuracy. Just for reference, I can keep all shots from my .38 target revolver inside the 10-ring at 25 yards.
