MA-9 9MM 4.5" Micro Glock-Style ARP Pistol – SBR Ready

AR-9mm

MA-9 9MM 4.5" Micro ARP Pistol – Glock Style | SBR Ready | Color Choice

The Moriarti MA-9 9MM 4.5" Micro ARP Pistol delivers an ultra-compact 9mm AR-platform configuration with Glock-compatible magazine compatibility, blowback operation and Moriarti color-matched components.

The updated MA-9 now features a Mil-Spec carbine receiver extension with an 8 oz buffer, replacing the previous proprietary micro buffer system. The carbine-style tube provides a more conventional rear receiver-extension configuration and makes this model SBR ready for customers who later choose to configure it in accordance with applicable NFA requirements.

At the heart of the MA-9 is a 4.5" 4150 CMV 9mm barrel with a 1:10 twist and 1/2x36 muzzle threads. The upper features a clean slick-side design paired with a free-float M-LOK handguard and matching barrel shroud.

The billet MA-9 Glock-style lower uses Glock-compatible 9mm magazines and operates in a Non-LRBHO configuration.

Choose your available anodized color for a coordinated Moriarti Micro ARP configuration.

Important SBR-Ready Notice

This firearm is sold as a pistol without a shoulder stock. The Mil-Spec carbine receiver extension provides a conventional receiver-extension configuration, but “SBR Ready” does not mean the firearm is sold as an SBR. Installation of a shoulder stock on a firearm with this barrel length can change its federal classification and should only be done in compliance with applicable NFA and other federal, state and local requirements.

Magazine

One Glock-compatible magazine is included. Magazine capacity will be supplied in accordance with applicable restrictions and the configuration available for the destination state.

FFL Transfer Required

This is a complete firearm and must ship to an appropriate FFL dealer for transfer. The receiving dealer should provide Moriarti with a signed copy of its FFL and reference the customer's invoice/order information.
