Stock Magpul PDR-C, shoots ~350 FPS. I have shimmed, lubed, and air sealed it though. Flash hider has been sanded, I can paint it black for you if you want. It’s also currently Tamiya wired, I can wire it to deans upon request as well. Cheek rest has a broken tab so it doesn’t lock in, but it’s a tight enough fit that it’s not going anywhere. Just makes it so you can pull it off. The upper receiver also has one body pin loop broken, but this doesn’t affect functionality. Pics of those areas can be provided if you PM me.
