Can anyone tell me what brand rail this is? It came on an 300 BLK upper and I really don't care for it. I'd like to know what brand it is so I can sell it. Thanks in advance for the help.
The upper is a slick side DPMS. Not sure on barrel manufacturer. Has low profile gas block. The rail screws on to the barrel nut with a single set screw on the bottom rail. The barrel nut looks like this, but the retainer ring is squared, 6 sides, like a regular nut. Thanks for the replies.
