I'm looking to sell a TNW Aero Survival Rifle for my best friend's widow. This carbine comes with threaded barrels and bolt faces for both 45 acp and 10mm. The conversion can be made quickly, and uses Glock mags. Accurate in both calibers. Also ejector easily converted for both a left or right hand shooter. Good reviews, like new with box, easy to clean, and had limited use by my friend.
