Moriarti MA-40 40SW 16″ Lightweight PCC – Choose Color, Non-LRBHO

.40 S&W Rifle: Specs & Features

The Moriarti MA-40 40SW 16″ Lightweight PCC brings .40-caliber performance to Moriarti’s modern AR-style pistol caliber carbine platform. Built as the 40SW counterpart to our popular MA-9 series, the MA-40 combines familiar AR ergonomics with a streamlined, lightweight configuration designed around the .40 S&W cartridge.

This 16″ MA-40 features a slick-side upper receiver, 15″ lightweight M-LOK handguard, Glock-style .40 caliber magazine compatibility, and Non-LRBHO direct-blowback operation. An 8 oz buffer complements the blowback system, while the Mil-Spec buffer tube keeps the configuration simple and clean without a stock or brace.

The 16″ barrel features a .578×32 threaded muzzle, providing a versatile foundation for compatible muzzle devices. Choose from available Moriarti colors to create a 40SW PCC that stands apart from conventional black carbines.

For shooters looking for a 40SW AR-style rifle, .40 S&W PCC, or 40-caliber carbine, the MA-40 delivers a purpose-built alternative to the more common 9MM PCC platform.
