My son gave me a Gat Crank for Christmas - that device that looks like a fishing reel crank that clamps on to a trigger guard. It happens to be a completely impractical toy that makes you giggle like a little girl when using it on a 10/22 with a 30 rd. magazine. I used it on my "nice" 10/22 a couple times but decided I didn't want to subject it to that abuse anymore.
I ran across a rusty old 10/22 with a cracked stock at my favorite Gun & Pawn that was perfect for a dedicated Gat Gun. $75 OTD. I started cleaning it up and, well, I got a little carried away.
I had a folding stock for a Mossberg 500 that I didn't have anymore that fit remarkably well. Cut 2" off the barrel, slapped some ugly UTG sights on it and a cheap flash hider from flea bay. Completely impractical but really fun!
