Angstadt Arms UDP-9 9mm Short Barrel Rifle

The UDP-9 represents a decade of refinement in modern rifle design. Since 2014, this platform has earned trust with professionals and shooters across more than 30 countries. It combines practical engineering with genuine craftsmanship.

Design and Construction

Precision-machined from 7075-T6 billet aluminum, both the upper and lower receivers deliver exceptional strength without unnecessary weight. The rifle tips the scales at under 5 pounds—a genuine lightweight that doesn't sacrifice durability or reliability. The slick-side upper receiver maintains a clean profile while the lower features an integrated flared magwell, threaded bolt catch, and last-round bolt hold-open functionality.

Barrel and Accuracy

A 6-inch chrome moly barrel with 1/10 twist rate and 1/2×28 TPI threading provides a solid foundation for accuracy. The included A2-style flash suppressor controls muzzle signature while the threaded barrel accepts standard suppressors for those who choose to run them.

Controls and Ergonomics

Ambidextrous controls throughout—Radian Weapons Raptor LT charging handle and Talon safety selector—ensure this rifle works equally well for left and right-handed shooters. The Angstadt Arms EMT-9 trigger paired with the Radian safety provides crisp, reliable operation. B5 Systems Bravo stock and grip deliver comfortable handling.

Modularity and Compatibility

The UDP-9 accepts Glock magazines and remains compatible with most AR9 and AR15 aftermarket components. The 5.5-inch M-LOK handguard features mounting interfaces at 3, 6, and 9 o'clock positions plus continuous top Picatinny rail for optics and accessories.

Important Note

This is a short barrel rifle variant and requires federal registration and a tax stamp per ATF regulations.

Includes: One 17-round Glock magazine
