I'm really schmoozing getting an 18" Stealth Upper and a Billet Lower from LaRue and now I am tosseling around what length of rail to get with it...

Any input? Any rule of thumb? General equasion? to go by? I'll put a verticle grip on it.

I kinda wish I could get the upper with feed ramps....but I guess feed ramps are not so important.

Thanks.

I think it's mostly subjective. I like the look of really long rails, but I like keeping weight down too. Usually the practical side of me wins. But you may have different priorities.

You may want your bipod way out front, or have a ton of gear to hang on the rails. Maybe figuring that out will help you make up your mind?

Thanks.

I am going to be more interested in creating a target rifle out of it, more than a "combat" rifle, so I don't think I'm going to have a lot of need for rail space. I'll mount a nice scope on it. Not a Red Dot or ACOG, a nice target scope with some length to it. No flashlight, nothing like that.

I think if you are going to go the target route, you will want to get a longer rail.  Do some looking around.  I believe you will like the way a "target" scope looks with a longer rail.  The longer rail seems to balance the look with the target scope better.  With an 18" barrel I would go at least 11 or 12.  Just my .02

I went with the stealth 18" with 12" rails. I put a nightforce 3.5X15 50 on it. With the sun shade on the scope and a harris bi-pod, I think the 12" guard was the right choice. When my LT lower comes in, I can complete the build and post some pics.

Go Here and build it to your liking...

Here is a pic of my 18/13.2 to give you a better idea of how it will look.  This is going to be more of a precision rig, so the added weight wasn't really an issue for me.  I think either the 12" or 13.2" is fine for the 18" barrel.  Obviously I'm still waiting on optics for mine.  Probably going to go with a Burris XTR 3x12.

I went 13.2 to cover the gas block.

Nice.

I was thinking 13.2, but after assembling it on line with the Leupold Mark 4 scope I wanted, the 12" looked really sweet.

Thanks for the feedback.

I like my 18" with 13.2" rail.  



It needs a bigger scope but I spent the money on a panic buy.
