Thats what I do. B's are no different than HD's as far as the barrel goes. That one up top has a B barrel in it.
I just contracted a BIG order of stainless clipped radial baffles with indexing notches to build integral 22's with from a CNC manufacturer that builds baffles for major silencer companies. Theyre to my design and I think they will be some of the best baffles for .22's around. PM me and we can discuss.
