Mine is a Bushmaster, M-faux. :-)
I love it. I think Bushmaster makes a quality rifle. But others do, too. The Sig 556 is catching my eye lately.
But be ready for the sticker shock... it’s not just the rifle, but its the optics. The optics will cost more than the rifle. Count on it. I have the Leupold CQ/T on mine and I love it. That lighted reticle, corrected for .223 ballistics... just rocks. But... I also love the Trijicon ACOG. I’m considering getting one.
Tell me about your Leupold CQ/T. I’m thinking of getting one but am having some doubts. For not too much more I can get an Aimpoint CompML2.
