Like the title says I'm thinking of picking up a mini 14 and I'm just looking to educate myself on them. I was batting around buying or building an AR but I think the mini is more in my price range. I know the newer ones have a thicker barrel but is there anything I should look out for on a used one? I like the looks of the tactical one from Ruger but I'm not sure I'm sold on the looks of the pistol grip, I'd have to put my hands on one to see if I really like the feel of it. Anyways thanks for any help.
