What brand barrel is this?

[Conroy]

A guy at work needs money and is selling a .300 blackout with a Palmetto State Lower and this upper and barrel. I have never seen the logo, so I am not sure of the brand. I am not familiar with AR builds. Thanks for any assistance

Maybe not the same length but that's a Radical FIrearms... Not the worst far from the best.
Upper

I'm guessing the "branding" you are looking at is just the brand for the forearm piece. Finding out that branding could lead to the barrel maker, but I doubt it. More than likely you'll need to find out who built the upper to find out who the barrel maker is...

There you go! (we were posting at the same time) Contact Radical Firearms and ask them who makes their barrels for their uppers. Still doesn't do any good if someone built the upper from components and just used the Radical Forearm, but if they bought the complete upper from Radical, they should be able to tell you who makes their barrels.

Awesome, that was fast. I'll do some more digging. The guy selling it needs money. I just wanted to see what type it is, I don't know anything about AR platform rifles, I just know it's a good deal for me.
