Surefire M500 for 16in barrel M4 style AR's.
This came on a rifle I bought and I do not want/need it and will be putting regular handguards back on it.
I put some batteries in it and everything works fine. Batteries not included.
All the buttons and rubber are good with no cracks.
A couple small scratches here and there. No cracks or major damage that I can see.
This one is a LED model.
