Update, October 9, 2026: ATF no longer requires a Form 4, tax stamp, fingerprints or registration for suppressors, short-barreled rifles, short-barreled shotguns or AOWs. They now transfer on a standard Form 4473 with a background check. Anything below that mentions a Form 4, a wait or a tax stamp was written before this change. What changed
The Rankin Industries Duty Pistol 556 10.5 inch is an AR-pattern pistol chambered in 5.56 NATO, from Rankin Industries, Western Sport’s own brand.
The 10.5 inch platform delivers compact handling for vehicle work, home defense, and close-quarters applications while maintaining the terminal performance of the 5.56 NATO cartridge.
This pistol is classified as a pistol under federal law, not a short-barreled rifle, and does not require ATF Form 4 approval for transfer. It is a serialized firearm requiring transfer through a licensed FFL.
Key Facts
Model: Rankin Industries Duty Pistol 556 10.5 inch
Caliber: 5.56 NATO
Brand: Rankin Industries
SKU: RI-Duty-Pistol-556-10.5
Why the 10.5 Inch Barrel Length in 5.56 NATO
A 10.5 inch barrel keeps the overall platform compact while still allowing 5.56 NATO ammunition to reach effective terminal velocities at typical defensive distances. Shorter than a carbine, longer than many pistol-caliber options, this length is widely adopted for vehicle and home use.
The tradeoff is increased muzzle blast and flash compared to a 14.5 or 16 inch carbine. Hearing protection is strongly recommended, and a quality flash hider or compensator becomes more important on this length platform.
Velocities from a 10.5 inch barrel are sufficient to ensure reliable fragmentation of M193 and expansion of barrier-blind defensive loads inside 200 yards. Send us a message to confirm barrel twist rate and threading if you plan to use specific loads or muzzle devices.
AR Pistol vs Short-Barreled Rifle
An AR pistol like the Rankin Industries Duty Pistol 556 does not have a stock, only a pistol brace or buffer tube. This keeps it classified as a pistol under federal law, so it does not require an ATF Form 4 or tax stamp.
A short-barreled rifle has a shoulder stock and a barrel shorter than 16 inches, which makes it an NFA item. If you later add a stock to this pistol, you create an unregistered SBR, which is a federal felony. If you want a registered SBR, start the Form 4 process first.

Frequently Asked Questions
Q: Does the Rankin Industries Duty Pistol 556 10.5 inch require an ATF tax stamp?
A: No, this is an AR pistol and does not require ATF Form 4 approval or a tax stamp. It transfers like any other handgun through an FFL. If you later install a shoulder stock, it becomes a short-barreled rifle and must be registered with the ATF before you make that change.

A: The barrel is 10.5 inches. Send us a message to confirm twist rate, gas system length, and thread pitch for your specific build, as Rankin Industries may update configurations based on available components and customer requests.
Q: Is the Rankin Industries Duty Pistol compatible with standard AR-15 magazines and parts?
A: AR-pattern pistols in 5.56 NATO typically use standard AR-15 magazines and many common components. For compatibility questions about specific magazines, optics mounts, or aftermarket parts, send us a message and speak with our gunsmith.
Q: Who builds Rankin Industries firearms?
A: Rankin Industries is Western Sport’s own brand. This is the house brand of a working FFL/SOT shop that has been doing custom builds and gunsmithing since 2007.
Q: What is the transfer process for buying this pistol in Texas?
A: You must be 21 or older to purchase a handgun from an FFL. You will complete ATF Form 4473 and pass a NICS background check. Western Sport handles the transfer on site. Send us a message for details.
