Started with a T4E Double barrel I picked up from KOB used.
Pulled the stock barrels. Well guess what fits perfectly in place of the stock barrels yup those are freak bore inserts. I had a piece of carbon fiber tubing I purchased for a feed tube but actually bored out to a .681 so it didn’t work for a phantom SC feed tube so I honed the inside down to capture the .681 freak inserts.
