MA-15 4.5" Micro Pistol | SBR Ready | Choose Color and Caliber

Built for shooters who demand the smallest AR-15 platform without compromising customization, the Moriarti Armaments 4.5" Micro AR Pistol delivers exceptional maneuverability in a rugged, forged package.

Featuring forged 7075-T6 receivers, a free-float M-LOK handguard, Mil-Spec controls, and a milspec 6 position buffer tube, this ultra-compact firearm is designed for reliability, portability, and versatility.

Available in 5.56 NATO, .300 AAC Blackout, 7.62×39, and .338 ARC, the platform accepts standard AR-15 components and is compatible with many aftermarket trigger systems, including many aftermarket forced-reset trigger systems (where legally permitted).

For enthusiasts planning an NFA build, this firearm is also an excellent SBR Ready platform. It is transferred as a Title I pistol (standard FFL transfer) and ships without a stock or brace. Customers wishing to configure it as a Short-Barreled Rifle must first comply with all applicable federal, state, and local laws, including ATF approvals.
