My old man is looking for a free floating tube for his mid length model 1 Ar he just bought. I've been out of the AR game for quite a while so all I see is 2 hundred dollar tacticoolies, and that's the cheap models. He's looking for a simple tube with just a few railed points. Weight is a serious concern since he's pretty handicapped. I started to search the other site but the "your shit sucks and my shit is gold" attitude was just unbearable. What do yall run? Prices? I appreciate any info you can throw out there!
