M7 Bayonet, bought one off Irunguns mounts right on my AR15A4. Good stuff, still sharp. The M7 design is a lot stronger then the newer M9's and they are available relatively cheap.
KAC still makes the RAS system, try any of their dealers..
The M5 RAS is rifle length, like these:What length covers are you looking for?
I think the OP is looking for the rail system, not just the rail covers?
A used set 1 yr old just popped up on EE a few days ago,,,asking $250 or something like that, says it's off his 20".Yup, I'm looking for the full rail system.

The M4 RAS is carbine length I think. I've seen a few M4 RAS on EE, but it's been a while since I saw the M5 set, and yeah, OST has been out for at least a month, maybe more. Not sure who else carries KAC.
What kind of optic is the diemaco wearing?
