Re: Newbie looking for help.
Your gun was made in 1969. The original H&R Inc. went out of business in Feb. 1986. The current owner of H&R 1871 (Remington/Marlin) doesn't support the older guns so they will not fit a barrel for you.
You may be able to find one in .30-30 if you watch the on-line firearms auction sites - it may take a while so be patient. Other than that - Numrich/GPC doesn't seem to have any in stock.
Note: The model 158 WAS THE combo gun - it was offered in various combinations, the most popular being 20 ga with a .30-30 barrel. Other lowier pressure rifle barrel combinations were also offered in .22 Jet and .22 Hornet. There was a "4 in 1" combo package offered 1964-67 which came with .20 ga, .410 bore, .30-30 and .22 Jet barrels.
As a stand alone frame, the M158 was offered in all the standard shotgun bores.
