Angstadt Arms MDP-9 Gen2 SBR 9mm Roller-Delayed Blowback

Angstadt Arms MDP-9 Gen2 SBR: Precision Meets Practicality

The Angstadt Arms MDP-9 Gen2 represents a thoughtful approach to the modern 9mm pistol caliber carbine. Built on roller-delayed blowback principles, this short-barreled rifle delivers reliable function with minimal recoil—ideal for shooters seeking accuracy and control in a compact package.

Design and Construction

The MDP-9 Gen2 features a monolithic upper receiver machined from 7075-T6 aluminum with a continuous top Picatinny rail and M-LOK interface for accessory mounting. The billet aluminum lower receiver shares the same premium 7075-T6 specification, ensuring durability and precision fit. Both components are manufactured in Charlotte, North Carolina, and covered by multiple patents reflecting years of development.

Ergonomics and Controls

Ambidextrous operation is standard throughout:

• Charging Handle: Non-reciprocating, swappable between left and right sides
• Safety Selector: Radian Weapons Talon ambidextrous safety
• Stock: Left-side folding Lage MFG rifle stock with sling mount; collapses to 15¾" for compact storage
• Grip: B5 Systems Type 23 pistol grip paired with an Angstadt Arms handstop
• Magazine Release: Extended, flared magwell with extended release lever

Trigger and Firing System

The Angstadt Arms EMT-9 trigger provides clean, predictable breaks. The system incorporates last-round bolt hold-open (LRBHO) on empty magazines, a feature that enhances training and operational awareness. The platform accepts most aftermarket 9mm PCC triggers for those seeking customization.

Barrel and Accuracy

The 5.85" chrome-moly barrel features a 1/10 twist rate optimized for 9mm projectiles. Black Melonite finish resists corrosion while maintaining a professional appearance. A removable 3-lug muzzle device (threaded 1/2×28 TPI) accepts suppressors and other muzzle attachments.

Magazine and Ammunition

The MDP-9 Gen2 accepts standard Glock 9mm double-stack magazines. Two 17-round OEM Glock magazines are included, providing 34 rounds of ready ammunition plus the chamber.
