MGM Barrel

I would call MGM or Shilen, to get the most accurate ansewer.. I have used MGM for a few custom guns, using Shilen barrels,, Very good quality..

I posted MGM's URL on your prior post, John. You can either call or ask your question on their forum. Kerry from MGM is a moderator on most of the forums. He's pretty good about responding. They're also on Facebook and Twitter if you're into social media.
