- Not to be confused with Zip gun.
The USFA ZiP .22 Long Rifle, commonly known as the USFA ZiP Gun, is a .22 LR semi-automatic bullpup pistol. The pistol is made by the U.S. Fire Arms Manufacturing Company under the brand ZiPFactory. It is the only known firearm that has been produced by ZiPFactory.
USFA was originally a maker of high-quality Colt Single Action Army replicas. The owner of the company, Douglas Donnelly, designed the ZiP .22 and shifted the company's focus to producing the weapon, selling all of their tooling to generate capital. However, the end weapon was plagued with a host of problems, including high unreliability, poor ergonomics, and unsafe operation. It was a commercial failure and led to the dissolution of its manufacturing company.
The ZiP .22 was designed by Douglas Donnelly, owner of USFA and ZiPFactory, as an affordable and modular pistol.
Donnelly's original plan to produce the ZiP .22 was likely to take a two-year break from manufacturing once USFA shut down to generate capital to produce the ZiP .22; to do this, he sold all the tooling from USFA's Colt Single Action Army replicas to generate the capital required to produce the molding tools in bulk for their products. The revenue generated by the products would then be used to supposedly buy new tooling for more Single Action Army replicas.
The ZiP .22 was first advertised in December 2012 on the ZiPFactory website, and was publicly showcased at the 2013 SHOT Show. The weapon began manufacture the same year; the weapon failed to generate any revenue for the company and was considered a failure in every regard. Manufacture is estimated to have lasted only a year, and it is estimated only a few hundred weapons were produced before ZiPFactory lost their Federal Firearms License.
The USFA ZiP .22 is largely made out of polymers, with very few metal parts. The weapon is extremely small, reminiscent of a zip gun, or improvised single-shot firearms, where the weapon got its name from. The weapon's extremely small size meant that the bore axis is almost completely aligned with the shooter's hand.
The gun has no grip, and users must use their index and middle finger to grip the trigger and a small loop underneath the trigger, and their palm resting on the back.
The weapon has no slide nor any visible bolt handle. Instead, there are two charging rods, both located directly above the muzzle. The longer rod is called the "ZiP LOAD" rod. Pushing it into the frame and releasing it will move the bolt back and chamber the first round. The shorter rod is called the "ZiP RESTRIKE" rod. Pushing it into the frame will reset the striker but not remove a round from the magazine. The two rods are interchangeable.
An inspection port on the top of the weapon allows the user to check if the weapon is cocked or not. A set of tools is hidden in the top plate and can be used to disassemble the weapon.
The safety is a small button located near the trigger guard. The magazine release is a small lever located behind the magazine.
The weapon is modular and allows for many customizable components from ZiPFactory to be used. The standard fixed sight top rail can be replaced with ZiPFactory's ZiP Ghost Rail Standard Fixed Sight (glow in the night version of the standard top rail), ZiPPIC Rail (1913 Picatinny rail), ZiPNite Rail (allows Glock-compatible sights to be installed), and ZiPSBR Rail (allows the ZiP .22 to be attached to another gun. Attaching it into a rifle turns the weapon into a Short Barreled Rifle under US law, hence the SBR name).
Other accessories include the BattleZiP Survival SBR Stock, a full rifle stock with a rail to attach the ZiP .22 on, which was never sold, a Suppressor Barrel Kit (for a suppressor or other muzzle accessories), an Action Hold Back (a special block that can be used to hold down the "ZiP LOAD" rod to hold the bolt open), a Belt Clip, and a drop-in Upgrade Kit ver. 1.0.1 that fixes a few issues related to sticky mags and sticky rods.
The weapon uses Ruger 10/22 magazines. It works best with BX-1 10-round magazines and has issues with using the BX-25 25-round magazine, which feeds too slowly. ZiPFactory manufactures the ZX-30 Reliability Upgrade upgrade kit that improves the spring inside the BX-25.
The ZiP .22 is noted to be very unreliable, and malfunctions extremely frequently. The most major flaw of the weapon contributing to its poor reliability was its poorly designed bolt. The extremely light polymer bolt cycles very quickly, which causes aftermarket magazines to fail to feed. The high bolt velocity also causes occasional case ruptures due to the pressure inside the chamber, jamming the gun. The lack of an extractor nor an ejector means that the weapon has significant trouble with extracting and ejecting a spent casing, further contributing to firearm failure.
In addition to its unreliability, the use of the two charging rods placed so close to the muzzle was very unsafe. Its ergonomics is also unconventional and awkward.

A .22 Magnum single-shot/semi-auto variant (SSE standing for Single Shot Express) made by attaching a drop-in ZiPSSE Module onto the ZiP .22. Was not made available for sale before the ZiPFactory lost their Federal Firearms License and their domain shut down.
