Musketoons had a brass or iron barrel, and used a wheellock, flintlock or caplock [1] firing mechanism, like the typical musket of the period. They were fired from the shoulder like the musket, but the shorter length (barrels were as short as a foot (30 cm) long) made them easier to handle for those in restricted conditions, such as mounted infantry and naval boarding parties.

An engine is described as undersquare or long-stroke if its cylinders have a smaller bore (width, diameter) than its stroke (length of piston travel) - giving a ratio value of less than 1:1. At a given engine speed, a longer stroke increases engine friction and increases stress on the crankshaft due to the higher peak piston acceleration.
A nock is a small notched piece that is attached to the rear end of the shaft, for engaging and receiving the propulsive push from the string during shooting. Nocks are made of either plastic or aluminum.
