This is brand new. I parted out my M4gery and forgot about ordering this barrel 3 months ago. It is chrome lined, has M4 contours and feed ramps and is threaded for a muzzle device. It comes with a standard FSB and barrel nut - that is all. Sorry, no pics I just opened the package to verify it's condition and wrapped it back up. The link to it from Del-ton's website is below. At this point, just wanting to get what I paid for it so $235 shipped gets it.
