Editing Gyrojet (section)

==Variants==

===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.

=== Gold Plated Gyrojet's ===
Gold Plated Gyrojet's (or commonly referred to as a '''''Golden Gyrojet''''') and its variants are amongst the rarest of all Gyrojet models with approximately less than 150 units ever made throughout their production with variants such as the Gyrojet Carbine being exceptionally more rare than the standard pistol. These weapons are often sought after by collectors alike due to their rarity and value throughout the years.

===Gyrojet Assault Rifle===

The Assault Rifle prototype is a unique variant of the Gyrojet with the purpose on reducing weight, sound, and recoil for Infantry troops during the Vietnam war, while potentially increasing range and bullet power compared to conventional firearms. It features many designs and ergonomics from the [[M16 rifle|M16 assault rifle]], while also containing a unique detachable box magazine from the grip that isnt seen in other Gyrojet configurations. 

Unlike other variants of the Gyrojet which are chambered in 13mm or 12mm rockets, the Gyrojet Assault Rifle would potenitally be chambered in new 6mm rocket (.24 caliber) ammunition, known as ''"Microjets"'', in order to increase the magazine capacity for infantry troops. During the tests conducted by the US Army, the rifle faced many issues from innaccurate rockets, misfire, and unreliability due to the humidity levels in places such as Vietnam, leaving it as an obscure prototype with few numbers produced.
=== Gyrojet Carbines ===

An experimental prototype of the Gyrojet that contained a longer 18 inch barrel, and a stock. These prototype's were used to solve the many acceleration issues that were seen in Gyrojet pistols due to rocket activation times by assisting the projectile through a longer barrel, helping the rocket accelerate much faster and travel longer ranges. A second variant known as the Model B, or "Sporting Rifle", was produced, featuring a rifle stock, grip, and an optional scope mount for ranged engagements.

Developed in the 1970's as a final effort to save MB Accosiates from bankruptcy, The Gyrojet Survival 2000 (known as a [[Derringer|Derringer pistol]]) is a modified starting pistol  with its upper barrel chambered in Gyrojet ammunition with roughly 20 models were produced of this version. The second variant of the pistol, known as the '''''Gyrojet Survival 2001''''' ,a was modified to fire Gyrojet ammunition but from both of its barrels. Only 3 models were ever created of this variant with only one surviving before MB Associates went bankrupt in 1975.

===Flare launcher===
{{Unreferenced section|date=December 2011}}
The Gyrojet principle was also examined for use in survival flare guns, and a similar idea was explored for a [[grenade launcher]]. The emergency-survival flare version (A/P25S-5A) was used for many years as a standard USAF issue item in survival kits, vests, and for forward operations signaling, with flares available in white, green, blue, and red. Known as the gyrojet flare, the A/P25S-5A came with a bandolier of seven flares and had an effective altitude of over {{convert|1500|ft|m|abbr=off}}.<ref>{{Cite web |last=staff |first=Sar |date=2007-11-01 |title=THE GYROJET FLARE LAUNCHER |url=https://smallarmsreview.com/the-gyrojet-flare-launcher/ |access-date=2024-09-02 |website=Small Arms Review}}</ref> Its rounded-nose projectile was designed to ricochet through trees and clear an over canopy of branches.

===Gyrojet Lancejet===
An [[underwater firearm]] variant of the Gyrojet called the "Lancejet" was considered for use by the United States military.<ref>{{Cite web |last=Spangler |first=John |date=2019-06-30 |title=MBA Gyrojet Mark I Model B Pistols and Carbines: Rocket Science Meets Reality |url=https://americansocietyofarmscollectors.org/wp-content/uploads/2019/06/2012-B105-MBA-Gyrojet-Mark-I-Model-B-Pistols-and-C.pdf |access-date=2024-09-02 |website=American Society of Arms Collectors}}</ref> It was planned and tested but not adopted; the inaccuracy of the weapon eventually removed it from consideration.<ref name="handgunsoftheworld3">{{cite web|url=http://www.handgunsoftheworld.com/i/018/GyroJet_032_1.JPG|date=2008-12-28|title=Image: GyroJet_032_1.JPG, (448 × 336 px)|publisher=handgunsoftheworld.com|access-date=2015-09-03|archive-date=2021-10-04|archive-url=https://web.archive.org/web/20211004215455/http://www.handgunsoftheworld.com/i/018/GyroJet_032_1.JPG|url-status=dead}}</ref>
