Great little rifles, and very fun, shot mine to 200 meters and could keep in the black, wished I'd never sold it, it was a Blue Sky.House gun? Be careful, with fmj, the .30 carbine will smoke a creosote telephone pole, lot of penetration. Pick some soft points or hollow points. I talked to Hornady and Cor bon about coming up with an xtp type bullet, many yrs ago, and they said they were working on it, after I sold mine, I really did not keep up with new ammo choices.
I bought some Remington soft point ammo the other day. That is what I'll keep in it here at the house when I get all the kinks worked out.
Hate to break the news to you, but, Mitchell and Universal were the Sig Mosquito's of Carbines.
C'mon Tom. Tell me how to strip it bare and fix it!
