So lever gun 357mag,44mag,454 Casull. 18" barrel threaded .578x28 syn. stock aluminum M-lok fore end, unsure of barrel twist rate I got the 44 mag, I can not comment upon the barrel threading of the other two calibers. Rear Peep sight threads in, not sure if std rear cowboy peep type thread or not. I will have to try one of my Skinner Sight inserts and see if the same thread. The peep slides up/down on an inclined rail, looks like what a dovetail for windage. Pretty light gun, with the AAC Trant 45 silencer, it is lighter than my integral Ruger 77/44 by John's Guns.
So CBC is a large ammo and firearms company based in Brazil owns Taurus/Rossi so most likely a very similar to those manuf. rifles. Owns Sellier & Bellot, Magtech, MEN ammo companies.
If it was not so damn cold out I would be giving shooting report rather than this silly info.
