I bought this rail for an upper I agreed to buy from a friend, and it already had a rail on it. I bought this because ive read over and over again, that the SureFire rails were the tightest and highest quality of the slide-in type of rail. I never ended up using it, so I'm selling it, $160 $150 $140
$130 shipped. It's in perfect condition, with white t-marks.
First, "i'll take it" gets it.
