Ruger mini-14. Although not really a "kid". But was 3 months shy of 18 years old. Thanks Mum. I think the I am going to go join the Army did it. Although that is not quite how it rolled. Took 911 to make me actually sign my life away to do that. But it did lead to me shooting expert all the time in rifle quals. She did not like my plan to much, but hell, she volunteered to go to Vietnam so had nothing to stand on. I think she figured it was better that I could shoot straight. Although an old school early 1990's era mini was not exactly on target. Just made me try harder. Never could shoot better than 5.5 MOA iron sighted with that thing before I played around with it in the mid 2000's. Now its a 2.5 moa after all the mods. Never getting rid of it. So out of left field for a Mum gift. She topped it on my 19th however. But not a kid then.
