This is posted on another thread but I thought I would start with this previous info. I bought a lone wolf barrel for my 10 it consistently had light primer strickes while my factory barrel shot perfectly. I suspected that the chamber was cut to long. I sent the barrel back to them they refunded my money minus 15% restocking fee and shipping, I have ordered a kkm barrel will post how it goes when I get it. Well got the KKM barrel in and guess what no light strikes, Lone Wolf insisted there was nothing wrong with there barrel, what a load of Hog*****! If my factory barrel worked perfectly and the KKM barrel worked perfectly, and I was lucky to get 2 to fire out of a clip on the Lone Wolf barrel the rest were light struck. They should have refunded all my money plus shipping for sending me that crap. Enough b*tching. This KKM barrel rocked it. No feed jams. Accuracy was awesome, came close to cutting a 6 inch sapling in two from 30 yds of hand with two clips of ammo (180 FMJ Masters ammo). I could not be happier with this set up. I think the barrel even looks better in the gun. Lesson learned; cheaper in this case defintley not better.
