Editing Gyrojet (section)

===MKI & MKII===
The Gyrojet MKI is the original variant of all Gyrojet weapons, being designed in 1962 and tested throughout the Vietnam War in small numbers. While being commercially sold across different markets throughout the mid 1960's, ammunition became very costly to produce the weapon and its ammunition ($200 per round), detering many poternial buyers who were interested in the weapon.

In light of the newly passed [[Gun Control Act of 1968]], any weapon firing an explosive-filled projectile over a half-inch in diameter (.50 caliber) was considered a ''[[destructive device]] and required paying a tax and obtaining a license''. As a result of the new laws, the Gyrojet needed to be redesigned to meet legal standards with the 13mm (.51 caliber) rockets passing the hard limit. The Gyrojet MKII was created as a revised version of the Gyrojet MKI with newly fitted 12mm (.47 caliber) rockets to meet standard protocols. However, the registration process was changed several years later with the ATF exempting the 13mm rockets, allowing them to the sold as a standard firearms.
