My Mini XCR makes all the hatred I had at SIG for making the 556 go away. I really see no need to own a Magpul or SCAR or whatever the new toy is going to be. Even if Sig said they would come out with the gun they where going to I would see no reason to purchase one at this point. I know some of you own and enjoy them, my hats off to you, I wanted what I was promised. I now have something MUCH better.
The XCR looks SO good in this configuration. It needs a comp Aimpoint ml3, a surefire light, and maybe a forward grip. I will leave it alone other then that.
As for if it works, I cleaned out the local Walmart of .223 Remington green box and have loaded the mags up. I will post a range report as soon as I get it out there.
