What lightweight rail for 12.5" barrel build?

[Variable]

Whats the OD of your suppressor? The SAR3 has a 1.5" ID.

I haven't picked a can yet either. I'm wishing AAC and Liberty would hurry the heck up and get their cans out. I'm leaning towards the Liberty "Triumph" because it weighs only 12oz. http://libertycans.net/centerfire-rifle-...s/triumph/ AAC's "Ranger3" http://www.advanced-armament.com/RANGER3_p_441.html is running a close second in my mind right now. I have to see who will bore one for 6.5 use. Either way, most of them are 1.5" diameter, and usually they are just under that in reality. Silencerco also has a really neat new lightweight hunting can out called the "Harvester" http://www.silencerco.com/harvester It'd be perfect for what I'm wanting if they'd ditch that dorky muzzle brake and shorten the stack a little bit.

I could use a fatter rail for an "SD" look, but I don't want the rail past the muzzle for the rare occasion I'd use it sans the can. I never liked fat rails, I bitch about them at work.LOL I keep Larue rails on my personal stuff, but it's time to go on a serious diet.LOL The BCM KMR10 only weighs 6.3 ounces with the barrel nut! I wish they'd make it in a length around 11.5".
