Notes: This is a semiautomatic magnum rimfire rifle, with folding sights, and drilled and tapped for a scope mount.

Notes: This is an AR-15A3 clone chambered for the new .243 Winchester Super Short Magnum cartridge or .223 Winchester Super Short Magnum cartridge. These cartridges, along with barrels 4 inches longer than normal, gives the weapons great accuracy. The weapon has been modified as little as possible to accommodate the new caliber, with changes to the barrel, bolt carrier group, and magazine well, as well as the recoil spring and mass. The weapon retains the flattop receiver with a MIL-STD-1913 rail. It does not, however, have any sort of flash suppressor or muzzle brake. The barrel is, however, of match quality.

Twilight 2000 Notes: This weapon does not exist in the Twilight 2000 timeline.

Notes: The PCR series is an AR-15A2 clone chambered for pistol cartridges. The weapon is mostly unmodified except for the modifications necessary for adaptation to the 9mm Parabellum cartridge, such as barrel (which is also shorter than normal), bolt-carrier group, magazine well, and sights; in addition, the weapon has no flash suppressor or muzzle brake of any kind. The handguards are short M-4-style handguards. The weapon is sold with 10-round magazines, but will in fact accept any sort of Glock-compatible magazine of the appropriate caliber. The PCR-30 is also similar to the other weapons of the PCR series, but is of lighter construction, and uses any magazine compatible with an M-1 Carbine. In addition, Olympic Arms also makes extended 40-round magazines for the PCR-30.

These rifles were largely discontinued after the demise of the Assault Weapons Ban, but in their place came the K series. These are for the most part identical to the PCR series, but being post-ban weapons, they are equipped with sliding stocks, flash suppressors, and can use larger-capacity magazines. All are available with 10 and 14-round magazines, but the K-9 is also able to use a modified Sten SMG magazine, while the others may use magazines modified from Uzi magazines. These magazines are proprietary, unfortunately. 16-inch barrels are standard; 20-inch barrels are optional.

It should be noted that on both the PCR series and the K series, there are forward assists; they don’t actually do anything however; being there simply for looks and in imitation of the AR-15.

Twilight 2000 Notes: The PCR-30 is not available, nor are any of the K series, in the Twilight 2000 timeline.

Notes: This is basically a faux semiautomatic version of the Russian AKR submachinegun, with enough changes to make it US Class 3-legal and a few other cosmetic changes. The Krinkov AOW is based on a pre-ban milled receiver. As the Krinkov AOW is based on a standard civilian version of an AK-47, the designer had to make a lot of changes to the operating mechanism to adapt it to the shorter barrel; however, the workmanship is excellent. The front grip is angled so that it better helps with stabilizing the weapon against barrel climb. There is a recoil buffer in the receiver and a good muzzle brake.
