Absolute Mess by Adrian Francis, Verified Owner, December 6, 2022
Got 20in barrel and it was HEAVILY used, dirty and rusted. Sent it back immediately. Hoping it was a fluke and reordered the 18in since there was an actively in stock. This review may change with the arrival of the new barrel. As of now, stay away.
