I recently sold a .223 bbl off a 2003 vintage SB2 frame. Bbl was the factory original. When I took the forearm off, the lug was angled slightly back. at about the angle the forend separates from the receiver. The screw fit nicely and there were no impact marks indicating damage. I just thought it was yet another variation in the H&R line.
The buyer, a regular here, accused me of knowingly sending him a defective barrel. Does anyone have any light to shed on the lug subject. I did offer to give a full refund plus shipping, but got no reply.
