Diagram of a Springfield Model 1855 Musket's lock mechanism. The small plate with the eagle on it is the cover for the Maynard tape system. Maynard's new system still required the musket's powder and Minié ball to be loaded conventionally into the barrel, but the tape system meant that the percussion cap no longer needed to be manually loaded onto the percussion lock's nipple.
The Maynard tape system gave the Model 1855 a unique hump under the rifled musket's hammer. The weapon could also be primed in the usual way with standard percussion caps if the tape was unavailable. The Secretary of War at the time Jefferson Davis authorized the adoption of the Maynard system for the Model 1855. [4]
The striker of the gun strikes the cap and fires the mixture. For larger guns an electric primer is used, the internal construction and action of which are precisely similar to the wireless tube already described; the exterior is screwed for the case. For percussion firing an ordinary percussion tube is placed in an adapter screwed into the case.

The Old State Armory building with Harpers Ferry Machinery was transferred to Confederate control in June 1861. Production began in October 1861 retaining the general form of the Model 1855, but without the Maynard tape primer mechanism and patch box.
Cap guns get their name from the small discs of shock-sensitive explosive compounds (roughly 1.4 to 1.6 millimetres (0.055 to 0.063 in) in diameter) that provide the noise and smoke, effectively the same as the Maynard tape primer and percussion caps used in real firearms of the mid to late 1800s but usually smaller and made from cheap plastic ...
The pressure applied to the tape allows the tape to have better contact with the surface and allows the physical forces between the two to build up. Usually, increased application pressure increases the bond of the adhesive to the substrate. PSA tape laboratory testing is often conducted with a 2 kg roller to increase test uniformity. [13]
