AR-40 16" Slick Side LRBHO Pistol Upper Assembly with BCG - .40 S&W | Moriarti Armaments

The AR-40 16" Slick Side LRBHO Pistol Cal Complete Upper Assembly is built with precision and performance in mind. Designed to work seamlessly with MA-9 Glock Style lower receivers, this upper assembly features a non-reciprocating slick side billet upper receiver with Last Round Bolt Hold Open (LRBHO) for a smooth and reliable shooting experience. The .40 S&W caliber ensures powerful performance in a versatile pistol-caliber upper for your AR build.

Key Features:

• Barrel: The 16" .40 S&W match-grade AR barrel is constructed from 4150 chromoly steel with a durable black nitride finish. With a 1:16 twist rate and .578x28 muzzle threads, this barrel provides high accuracy and performance. It comes with a linear compensator to reduce recoil and muzzle rise, enhancing shooting comfort.
• Upper Receiver: The slick side billet upper receiver is crafted from certified 7075-T6 aircraft billet aluminum, hard-coat anodized in black per MIL-8625 Type 3 Class 2. This robust receiver is compatible with AR-15, AR-9, and AR-45 MIL-SPEC components for flexible customization.
• Gas System: Designed for a blowback gas system, this upper is optimized for pistol-caliber rounds, offering smooth cycling without requiring feed ramps.
• Handguards: The 15" free-floating slim M-LOK rail provides a lightweight, sleek, and customizable handguard that is made from high-quality aircraft-grade aluminum and anodized for added durability and resistance.
• BCG: The included AR-40 .40 S&W/10mm ramped BCG is Glock & Colt compatible. Made from US-made 8620 steel with a mag phosphate finish, this BCG is precision-milled for use with Glock-style MA-9 lower receivers. The M-16 cut also makes it compatible for use in full-auto MGs and other legal machine guns (following all BATFE rules).
• Charging Handle: Comes with a standard AR-15 charging handle, providing smooth and reliable operation.

This AR-40 16" Slick Side LRBHO Upper is perfect for anyone looking to build a high-performance, .40 S&W AR while maintaining compatibility with Glock-style lowers. Whether you're assembling a pistol or a rifle, this upper assembly provides exceptional functionality and reliability.
