About the AR Pistol

An AR pistol is a firearm that resembles an AR-15 rifle but is designed to be classified as a pistol. This pistol has a shorter barrel compared to a standard AR-15 rifle and typically, the barrel length is less than 16 inches.

Unlike an AR-15 rifle, an AR pistol does not have a traditional shoulder stock. Instead, it might have a stabilizing brace, which is designed to be strapped to the forearm for better control. This distinction is crucial because adding a stock to a firearm with a barrel less than 16 inches would classify it as a Short-Barreled Rifle (SBR), which is regulated under the National Firearms Act (NFA).

Specifications

  • Caliber:5.56 NATO/.223 Remington, .300 Blackout, 9mm, and .308 Winchester.
  • Barrel Length: Ranges from 7.5 inches to 14.5 inches.
  • Overall Length: 20 to 30 inches, depending on barrel length and brace configuration.
  • Weight: 5 to 7 pounds, unloaded.
  • Action: Semi-automatic, gas-operated direct impingement, or piston-driven.
