I have a Troy VTAC Delta, a Troy Delta, and the Midwest Industries MCTAR-20XG2 on each of my AR's. I've been very pleased with all three. The Troy VTAC is the lightest feeling of all three, and I do like the feel of the tubular Troy Delta rails. The Midwest was easy to install. Removing the delta ring is easy if you have a dremel tool. If I can remove one without screwing up an upper/barrel then anyone can. I like my Midwest too.
