Rankin Industries Duty Pistol 556 10.5 inch

Product Description

The Rankin Industries Duty Pistol 556 10.5 inch is an AR-pattern pistol chambered in 5.56 NATO, designed and built by Lance Rankin and the team at Western Sport in Roanoke, Texas. This is a house-brand firearm from a working gunsmith shop that has been building custom guns since 2007.

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. Rankin Industries produces this model in-house with direct oversight from Lance Rankin.

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. Call 817-393-4000 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.

Call our shop at 817-393-4000 if you have questions about legal configuration, braces, or converting a pistol to an SBR through the ATF.
