Yep, the CVA is a break action single-shot. It's built by Bergara and imported with CVA stamping their name on it. The original stock is not a thumbhole, I added one of their Omega thumbhole stocks to it.I love that is it a CVA w/the thumb hole stock single shot? That looks cool as heck. When I first saw it I just blew by it and thought it was one of those .410/.45 L.Colt "survival rifles" from NVA or someone like that but I guess its not. I like it tho.
In Europe this rifle is called the BA13 and is very popular. Mine has a 2lb crisp trigger pull and will shoot 1/2" groups at 100yds with factory ammo. Super great value rifle and built like a tank. Top pic is 100yds. Bottom pic is 50yds with cheap plated subsonic reloads.
