What was the first short barrel rifle?
In the decades following World War I, the standard battle rifle used by armies around the world had been growing shorter, either by redesign or by the general issue of carbine versions instead of full-length rifles. This move was initiated by the U.S. Model 1903 Springfield, which was originally produced in 1907 with a short 24-inch (610 mm) barrel, providing a short rifle that was longer than a carbine but shorter than a typical rifle, so it could be issued to all troops without need for separate versions. Other nations followed suit after World War I, when they learned that their traditional long-barreled rifles provided little benefit in the trenches and merely proved a hindrance to the soldiers. Examples include the Russian Model 1891 rifle, originally with an 800 mm (31 in) barrel, later shortened to 730 mm (29 in) in 1930, and to 510 mm (20 in) in 1938, the German Mauser Gewehr 98 rifles went from 740 mm (29 in) in 1898 to 600 mm (24 in) in 1935 as the Karabiner 98k (K98k or Kar98k), or "short carbine".

These toys operate by introducing a little carbide into a chamber containing some water where it reacts immediately to release acetylene gas. A few seconds later (long enough for the gas to spread out in the chamber, but short enough for it not to be lost out the barrel), it is ignited. A means for introducing fresh air for the next explosion is also provided. Acetylene in air has the widest range of explosive limit of any common chemical and also a very low ignition energy, a combination which very reliably produces a loud “bang” explosion compared to other vapor explosions.
