I’m willing to bet they are Great Lakes Firearms barrels (GLFA). Pretty good from the little I’ve heard about them. The M4 feed ramps aren’t a good idea in my opinion. Although, if they are set up like Tromix’s, they won’t be an issue. Tromix basically takes a standard barrel extension and cuts down some of the bottom lug at an angle. If that’s the case, it may take a little blending/smoothing out, but should work just fine. If the barrel you’re talking about, is indeed a standard, non-modified M4 extension, you could always do the same thing yourself. It will just take some time.
