I have a basically new 7" NSR for sale for $200
$175 shipped. I took it off an 8" 300BLK upper that was never fired. I replaced the 7" with a new 9". Therefore, you will get the 7" NSR shipped with all of the other new parts that came with the 9" NSR that I just received. The only blemish on the rail is a very small cosmetic scratch on bottom of rail.
Please IM or email with any questions.
