Bought for a build, and it didn't work with my other parts, had to go a different way. Tiny scuffs from mounting, but no damage and never fired or had anything mounted on it. These are about $220 on most websites. Most useful feature is that it is the only production handguard (that I know of) that will fit over a 1.75" can and long enough to completely cover it on an SBR.
Thanks for looking!
