Ive recently purchased a Lone Wolf 9mm barrel and decided to try it out this afternoon. The barrel is threaded and has a Lone Wolf compensator on it as well. The guide rod is stainless with 20lb spring and a recoil buffer. It's having trouble feeding and extracting spent case. I tried 2 different types of ammo with no prevail. I went back to the stock guide rod with 17lb spring and no difference. I did notice the feed ramp not having the same angle as the stock barrel. Is this a normal occurrence and is it something I need to have grinded down from an armorer? Would you know someone who tackles such jobs?
