Like new, shot maybe 2 mags of ammo through it. Comes with 2 mags. It is the first M&P Sport so it doesn't have a dust cover or forward assist.
Message me if interested and I'll send you my co-worker's phone number.
Took off one of my rifles a couple years ago and just never put it back on anything. Needs batteries since the ones it had are now dead. Took batteries from another light to test it and it works fine.
