CASV-EL all day long. Bomb proof tough and as close as your going to get to a monolithic FF rail system under $300! Caveman simple install. I also like the way tac lights mount to this thing on the angled bits. Its octagonal and the bottom comes off if you got a M203 (who doesn't have a couple of those just laying around).
As mentioned before it is probably the single most comfortable rail. Comes with all the rail sections you would ever use so you can customize to your liking.
I miss mine so bad I think I might just order a FDE one right now.
I have a personal hatred for ARMS so I would use tape and zip ties before buying the SIR.
