I do not accept returns on barrels due to liability and cannot sell them as new once they are shipped out and returned. If there is a function issue obviously I will make that right if it is due to my product. Please, please, please make sure the barrel length and configuration is the proper one for your platform. I want people to be happy with their purchase and get the proper barrel for their platform in the length that is best suited to their purpose. If unsure please contact me first and I can possibly help with identification and input.

Great barrel, it actually fits tighter than the OEM Sig barrel, which is awesome! Zero did’t change either. Groups are nice and tight..I couldn’t be happier! If you’re on the fence trying to decide, don’t wait…you need this! I couldn’t out shoot the barrel, it was flawless. Oh, and it shipped the same day I ordered it!
