What models of shotgun barrels fit this model. I'm looking at a model 58 and I wonder if it will fit. I want a 20ga barrel and maybe a 30-30.
mine has a screw to attach the forend, so is ok to buy a 20ga or 30-30 barrel for it? will 158 swap with 58 barrels?All M158 (H&R Inc single shot) frames are ductile cast iron, so you're limited to shotgun and low pressure rifle like 30-30, 357mag, etc. Late M158 frames are pretty much compatible(when fitted properly) with modern( 1987> NEF/H&R 1871) barrels, earlier M158 barrels with snap-on forends will pose a problem with forend attachment, later M158 barrels had screw attached forends like modern barrels.
