4 of 5 Fast shipping, good product March 28, 2023
Reviewer: Chad from Oxnard, CA United States  
My barrel was shipped out very quickly.  Communication was solid via email.  The conversion fit perfectly without any need for tooling, it locked up nice and tight with zero play.  Rounds feed smooth.  My only complaint is that it came with a silver thread protector instead of black like the pictures.  I noticed that they are out of stock on the website though.  I wish I would have been notified beforehand. I will just grab a replacement elsewhere.
