Moriarti MA-40 40SW 4″ Brindle Micro ARP Pistol – LRBHO | SBA3

The Moriarti MA-40 40SW 4″ Brindle Micro ARP Pistol brings Moriarti’s distinctive Brindle Series styling to the compact .40 S&W platform. Combining a 4″ Micro ARP configuration, LRBHO functionality, SBA3 adjustable pistol brace, and custom multi-tone Cerakote finish, the Brindle offers a completely different look from a conventional black PCC.

Built around a 4″ heavy-profile 4150 CMV barrel, the MA-40 features a slick-side billet LRBHO upper receiver, compact 4″ free-float M-LOK handguard, slim flash can, and dedicated .40 S&W blowback system. The Moriarti billet PCC lower is designed around compatible Glock-style .40 caliber magazines.

Custom Brindle Cerakote

The signature Brindle finish combines FDE, Coyote Tan, and Bronze across selected components for a distinctive multi-tone appearance. Because each firearm is individually finished, variations in color placement, transitions, shades, and pattern make each Brindle configuration unique.

The compact platform is completed with an 8 oz PCC buffer, Mil-Spec receiver extension, and SBA3 adjustable pistol brace, maintaining the established configuration and visual identity of Moriarti’s Brindle Series.

For customers looking for something beyond a standard 40SW pistol, the MA-40 Brindle combines Micro ARP proportions, .40 S&W chambering, Glock-style magazine compatibility, LRBHO functionality, and Moriarti’s recognizable custom finish in one purpose-built configuration.
