Looks like the .308 AR is going to become even more widely available. It isn't an AR-10, technically, but, like the DPMS guns (from which its parts come, if I'm not mistaken) it's a sorta scaled-up AR-15. http://www.remington.com/products/firearms/centerfire_rifles/model_r-25.asp
It comes from DPMS parts? Pass. The only thing worse than a DPMS is, well, anything from Olympic Arms. Edit: I did have them write DPMS into the "approved" list of officer bought AR's at work, but only because a shitty AR is better than no AR. But, only because of that.
Learn to shoot right handed? I mean if the one in nine of us that are left handed can learn to use a right handed can opener, then shooting off hand should be a breeze.
...yeah, no. I've been trying to get used to shooting lefty, and it just doesn't work. Although last time I had a breakthrough. It gets easier when I shift my stance and not just my shoulder!
It's funny. My uncle was a lefty and he shattered his shoulder in an accident at work. The following deer season it was too painful to shoot left handed and he had to teach himself to shoot right handed.
