It's a bootleg. - Bootleg Inc Rifle Length Gas Tube

I've used Bootleg components before. As usual, the quality is high even with this simple gas tube. The finish is nice and helps blend the tube into the rail instead of shining through. I've had good luck out of Bootleg parts in other builds. I look for parts from certain company's, like Bootleg, just so I know there won't be any issues when the part arrives.
