Technically not a rifle in non-class 3 form but there's a pistol version with a sb arm brace. I'm sold as long as it actually comes out this October.

The rifles are just as nice but I would rather take my chances with the pistol before paying for another tax stamp. Resale on the pistol would be just as attractive if for some reason I didn't find it suitable for my needs. Re-transferring a class 3 less than 2k usually results in a loss in my experience.

I'm interested in one of these as well.............just wish the prices of the mags werent as high as they are

edit: nevermind, my smartass ways deceived me
