I'd have no luck at all? Well bought the Sk-19 near two months back. Probly shot five or six hundred rounds through it. The best I could do was about 1 to 1-1/2 inch at seventy-five yards with a few to many fliers. I was pretty sure I saw some keyholing going on as well. I thought it should do better so took the barrel off looked it over and found the last 1/2 inch or so was looking pretty bad. Contacted the seller and they said to send it in. Good customer service and an easy thing to do so I sent it off. Well I received an e-mail a week or so later saying they were sending me a new barrel. USPS delivered my new barrel today. Such a deal

The original barrel as received on the gun.

Same packaging I sent it back in albeit a bit worse for wear and tear.

My new barrel arrived like this. :^( GRRR...
