Overview
The Angstadt Arms UDP-9 Pistol is a purpose-built AR-15 style firearm optimized for the 9mm Luger cartridge. Engineered for reliability and compatibility, this platform integrates a compact profile with proven features for a range of applications, from competitive shooting to personal defense. Its design focuses on functional utility and seamless interaction with common accessories and magazines.
Key Features
Optimized AR-15 Platform
Chambered in 9mm Luger, the UDP-9 offers a familiar AR-15 manual of arms in a pistol-caliber format. The system incorporates a last round bolt hold open (LRBHO) feature, enhancing operational efficiency and providing clear status indication. Designed to accept Glock magazines, it ensures broad compatibility and simplified logistics for users already invested in the Glock ecosystem.
Refined Receiver Design
The UDP-9 receiver is precision-machined from aluminum and finished with a Flat Dark Earth Cerakote for enhanced durability and corrosion resistance. It features an integrated Mil-Spec 1913 Picatinny rail for optics and accessory mounting. The flared magwell facilitates expedited magazine changes, while an oversized trigger guard accommodates gloved operation. To maintain a streamlined profile, the design omits both a forward assist and a dust cover. A threaded bolt catch screw ensures secure retention and simplifies maintenance.
Barrel and Handguard Integration
Equipped with a 6-inch Black Melonite threaded barrel, the UDP-9 is prepared for suppressor integration, allowing for the attachment of muzzle devices. The Melonite finish provides superior wear and corrosion resistance. A 5.50-inch free-float ultra-light M-LOK handguard provides a rigid platform for mounting M-LOK compatible accessories without influencing barrel harmonics.
Fire Control and Ergonomics
The UDP-9 utilizes a 9mm bolt assembly designed for compatibility with a standard AR-15 hammer, ensuring robust operation. A Mil-Spec AR-15/M4 fire control group provides reliable trigger function and allows for compatibility with most aftermarket 9mm PCC triggers. Ergonomics are further enhanced by Black B5 Grips, providing a secure and comfortable purchase.
Magazine Compatibility
The UDP-9 is engineered to accept all Glock aftermarket magazines. For optimal performance and reliability, the use of factory Glock magazines is recommended. The pistol is supplied with one 15-round magazine.
