The 1841 model field cannon was designed and built to be a state of the art mobile artillery piece designed to support the infantry in the massed battles prevalent at the time. It was built with an all brass 3.6 inch diameter smoothbore barrel and measured 60 inches in length. It was claimed to be lethal at 1500 yards but accuracy at that range was not very high and true effective range was more like 1000 yards depending on the type of ballistics used for a shot. It was the standard US Army field piece between the 1840s and the early 1860s.

It had a conventional carriage and limber that were used to transport, and supply the gun that were standard for the period. The limber provided a typical load of 105 3.58 inch basic shot that weighed 6.10 pounds each. It also carried 30 canister shots and 15 spherical case shots.
