Moriarti MA-40 40SW 8″ LRBHO Pistol – SBA5 | Choose Color

The Moriarti MA-40 40SW 8″ LRBHO Pistol updates one of Moriarti’s established .40 S&W PCC configurations with a cleaner modern setup built around an 8″ barrel, slick-side LRBHO upper, SBA5 adjustable pistol brace, and Glock-style magazine compatibility.

The 8″ barrel provides a balanced middle ground between Moriarti’s ultra-compact MA-40 Micro pistols and full-size 16″ PCC configurations. A free-float M-LOK handguard provides a streamlined front end while maintaining useful accessory space.

At the heart of the platform is Moriarti’s LRBHO – Last Round Bolt Hold Open – system, paired with a dedicated .40 S&W blowback bolt and Glock-style billet PCC lower. An 8 oz PCC buffer is matched to the direct-blowback operating system.

The updated configuration uses an SBA5 adjustable pistol brace, bringing this established MA-40 platform in line with Moriarti’s current mid-length PCC lineup.

Available in multiple Moriarti finishes, the MA-40 8″ LRBHO gives shooters looking for a 40SW AR pistol, AR-40, .40 S&W PCC, or Glock-style .40 caliber AR a conventional mid-length option between the Micro and full-size MA-40 platforms.
