Moriarti MA-9 9MM 7.5″ LRBHO Pistol – SBA5, Slick Side

9mm Pistol: Specs & Features

The Moriarti MA-9 9MM 7.5″ LRBHO Pistol updates one of Moriarti's established AR-9 configurations with a cleaner, more modern setup featuring an SBA5 adjustable pistol brace, slick-side billet upper and Glock-style MA-9 lower.

Built around a 7.5″ 4150 CMV Government-profile barrel, the MA-9 uses a blowback operating system and incorporates Last Round Bolt Hold Open (LRBHO) functionality. A free-float M-LOK handguard maintains the streamlined profile while providing a continuous top rail for compatible accessories.

This model includes one Glock-pattern 9MM magazine. Optics and sights are not included.

FAQ

What is different about the LRBHO MA-9 compared with Moriarti's Non-LRBHO models?

This MA-9 incorporates Last Round Bolt Hold Open (LRBHO) functionality, while Moriarti's Non-LRBHO configurations use a simpler slick-side architecture without that feature.

Product Image Notice

Images may not be the exact representation of the product. Component appearance, handguard design, grip, muzzle device and other non-material details may vary based on production and availability. Optics shown in any reference or legacy images are not included. Please refer to the product description and specifications for the configuration included.

FAQ

Does it ship to an FFL?

Yes. This is a complete firearm, so it ships to your local FFL dealer for transfer. The buyer must meet all federal, state and local requirements.

What magazines does it use?

Glock-pattern 9mm magazines.

How does it operate?

It is a direct blowback pistol-caliber design with no gas tube, using a heavy PCC buffer for reliable cycling.

Does it have last round bolt hold open?

Yes. It has LRBHO, so the bolt locks back after the last round.

Can I add a stock?

Adding a shoulder stock to a pistol with a barrel under 16" makes it a short-barreled rifle under the NFA. Do it only in compliance with federal and state rules.
