Hay BigBill: Git yorself onna dem carbines - they are too much fun not to have one. You are correct, ammo is fairly inexpensive and you don't have to chase the 'clips'.
My sister bought one a couple of years ago at a gun show in Saratoga. She saw it first and put a down payment on it before she even asked me about it - she like it for the size and weight. The darn thing even came with the sight and sight attachment for the grenade launcher, and all for $325. She skips cans with it at 50 yds. I'm happy.
Hope all is well and that Christmas was good for you. You must have gotten the same snowstorm we did. How did you fare??? Mikey.
