This setup has approximately 2k or so rounds (BCG closer to 500) both suppressed and unsuppressed. This upper will reach 16" with the proper muzzle device.
The barrel nut is ate up due to a combination of shitty Spike's barrel nut and my caveman brain. It's torqued to spec and runs fine but I would plan to replace it if you ever need to uninstall it
