Phoenix Dynamix's AR-22 Series of High-Powered Assault Weapons are all based around the original AR-22 which was originally designed by Johnified America's DARPA. The weapon was designed to fire the high-powered JSA .45 Caliber Rifle round, but when it was actually built, the slightly longer .450 Phoenix(11.45x75mm) round was used. Johnified America was unable to produce AR-22's in any quantity themselves, so through a deal with The Phoenix Milita government, Phoenix Dynamix began producing them in mid-2004. All versions of the AR-22 are still for sale on the open market except for the the A4 series(which is sold with restrictions) and the B series(which never entered full production). The AR-22 and its variants continues to sell at a steady rate.
Phoenix Dynamix began making a sniper variant, the SR-22 shortly afterward. It was a bit lighter than the AR-22, but sported a heavier, longer barrel and integral bipod. It was a semi-auto only rifle and configured for use with 20 round magazines and a 10x telescopic sight. The SR-22 would remain a top selling sniper and designated marksman rifle for many years to come.
In the Fall of 2004, certain special operations units as well as paratroopers within TPM requested a shorter, carbine version of the rifle. At first a simple shortened rifle was made, the AR-22A1. The AR-22A1 was essentially a chopped AR-22 without any under barrel weapons systems attached. While it was accepted by paratrooper units, it left the special forces dissatisfied, and they rejected it after live fire testing.
Through close cooperation with the Special Forces, Phoenix Dynamix developed the CAR-22 which was a non-bullpup configuration. The design borrowed some of the action from the MG-22, which was also in development at this time. The CAR-22 was finished just as the MG-22, a squad automatic weapon variant of the AR-22, hit the market
The MG-22 was designed as a heavy, fast firing complement to the relatively slow firing AR-22. It would enter service alongside AR-22 and AR-22A1's but was never fully adopted in the Squad Automatic Weapon role. At best it could be considered a light machine gun, but most often performed the role of a medium or general purpose machine gun due to its weight and bulk.
The design went much unchanged for quite some time, until TPM adopted a 30mm grenade launcher and decided to modernize its forces. The brass wanted an AR-22 with an integral laser sight, aiming light, and 30mm grenade launcher, as well as a standard rail system for additional scopes and other add-ons. Thus the AR-22A2 was born and it served as the main weapon of The Phoenix Milita, Tyrador, and Johnified America for many years.
While the AR-22A2 was a very highly thought of weapon amongst regular forces, TPM special operations units found it too cumbersome, and retained the older CAR-22 or AR-22A1 variants for a time. But then in 2006, at special request of the KOP, the AR-22A3, which combined several design features of the previous variants into a manageable package. The AR-22A3 was considered the "best" AR-22 variant among the military despite the AR-22A4 replacement program. The AR-22A3 can also be converted to fire .450 Vixen round without the use of tools.
The unproven A4 series is steadily replacing the A3 and the A2 in regular units. The AR-22A4 is significantly lighter and smaller than previous AR-22 and is manufactured in a number of variants. Mod 0 is the general designation given to the the stock AR-22, with no underbarrel weapons
The AR-22A4 Mod 1 features an integral 30x55mm grenade launcher and leaf sight.
The AR-22A4 Mod 2 features an integral 8 gauge shotgun.
The SR-22A4 is very different from the original SR-22, and is more similar to the AR-22A4 than to any other weapons system. It features an integral lightweight bipod and custom sight clasp combination rail system for mounting all known accessories.
