"I put this on my Tippmann m4

Real-Steel spec
Nice look
Includes all mounting accessories
The included nuts have Teflon tape on them
It seems very sturdy

My rail seems to be a little off center, but its only like 2mm (it could be the barrel)

"Bought this originally for my LM4. I mounted it with ease, and was pleasantly surprised by the secure fit. This product ended up working so well I have it now mounted on my AR15. Works like a champ, no complaints.
