Looking for list of barrel manufacturers

[LRRPF52]

Satern makes Midway USA (AR Stoner) and Brownells Grendel Barrels. They use MAXIM Bolts and are the Grendel II chamber. LRRPF52 has one for sale on the build box package right now with reloading dies and books.

Liberty makes the AR-Stoner barrels. Satern makes cut-rifled barrels at a much higher price point, since they are single-point cut-rifled.

I have examples of both. Once the reamer issues were worked out, the Liberty barrels are a decent pipe. If you still don't understand the role that the ejector plays in potential feeding issues with right side feed lip presentation, you might consider reading this:

If you have any questions or need to attack my character, feel free to PM me. It doesn't look good when you ask for my help here, send kind messages, then go on another forum and conduct yourself in that manner. Maybe nobody every taught you in your formative years, but this is what is referred to as being 2-faced, untrustworthy, and a very bad indicator of character. This forum has always been a place of gentlemanly discourse. If you're looking for strife, envy, or malice, I think you'll be in appropriate company elsewhere.
