Not big on bullpups at all, lost most of my hearing in my left ear from a 10/22 conversion I did some 20 years ago. I was so hot to trot to shoot it that I was not thinking about anything else. Before I could let off the trigger I had 3 or 4 hot casings stuck in my ear. The ringing has never stopped either.
and Neal the only difference is no stock so the distance performance is the same as the original weapon for distance. Shooter comfort is the problem and lack of bipod for a steady rest.
