I've been using a Surefire rail sytem on my m4 for about a year now. It hasn't been the best solution for my rifle, since I always end up having to re-tighten it two or three times every range visit. I'm using an m4 type AR with a 14.5 inch barrel w/ perm. attached flash suppressor, so this limits me to what kind of rail to use, and I don't want to go and cut off my delta ring to accomidate certain free-float systems. I'm thinking of a non-free float rail. I've always wanted a RAS, but before I park 300 bucks on one, I was wondering if any of you guys out there knew of a good non free-float system out there. I don't want a piece of crap system, but I don't want to waste the money if there's something just as good out there. Thanks for the input.
Also, where's the best place to find a RAS?
Best,
Dan
