Hi folks, learned a lot from the pros here, first post! Bought a 6" KKM barrel today for my 17 - awesome. Did a search and found out KKM is out of Carson City, NV which is just 40 miles from home. Really good man runs the shop named Kevin, highly recommend him. Anyway, 100 rounds today without a failure and don't expect any. Nice long distance shooting @ 50 yards. Stoked! Kevin says he can thread the end someday for $55.00. Next up some good sights. $165 for the 6", no tax, good people. Carry on.
