I am having huge problems with pinning my barrel on my k-var krink kit. I drilled a beautiful hole with a letter H drill that gave me a hole of .270 and my pin with the kit was .276. So I tried hammering it in...needless to say I F*#ked everything up. The pin is about 3/4 of the way through and It will not move. I hate to order more drills...Has anyone ever used a roll pin for the barrel pin??? WHAT DO I DO!!!!!!!!
