I just acquired an underhammer percussion rifle in a trade over the weekend in 36 caliber. It is stamped on the barrel Heritage along with Allen and Numerick on the barrel.
The bore is very nice and the action seems to function well but seems about as simplistic as I've ever run across with the trigger guard acting as a hammer spring! The rifle also is equipped with a brass hand guard rail behind the trigger guard and a Lyman tang mounted peep sight\front ring sight.
It will be a while before I can take this one out to the range for some testing (weather thing) but would like to hear from anyone who has had experience and or any information about this unique rifle.
I had this same underhammer rifle (Numrich/Hopkins & Allen) in .45 caliber; actually .44 in real life. They were popular in the 70's and were known for being accurate. Simple? You bet. Means not much to go wrong. Barrels were made almost always by Douglas and were top quality.
"In God We Trust". For everything else, always cut the cards.
For all of the years that was advertised in the gun magazines, I have only seen one or two at a gun show. I have never seen one in use at the range or in the woods. Based on other Numrich m/l guns I have seen or owned I would carefully check it over for (1) proper sight alignment, (2) proper sear and safety notch engagement.
