Design and Ergonomics

The ANGSTADT ARMS UDP-556 is chambered in 5.56 NATO and features a 16″ chrome moly barrel with a 1:7 twist. That twist rate stabilizes a wide range of projectile weights, making the platform versatile for both light competition loads and heavier 62–77 grain projectiles used for longer-range precision. The rifle ships with a B5 Systems SopMod Stock and a B5 Type-23 grip, offering proven ergonomics and immediate familiarity for operators and competitive shooters alike.

Barrel, Handguard, and Accuracy

This model uses a free-floated 16″ ultra light M-LOK handguard that reduces fore-end weight while providing direct mounting points for lights, bipods, and optics. The 1:7 twist on a chrome moly barrel balances stiffness and weight; combined with a barrel threaded 1/2×24, you can easily attach muzzle devices or suppressors depending on your local laws and mission profile. The free-floated design supports tighter groups and consistent point of impact under sustained fire.

Modularity and Field Use

With its standard M-LOK handguard and 1/2×24 threading, the UDP-556 is ready for customization. The included 30-round magazine and all-black finish make this model practical for range work and match setups. At a listed price of $1,471.99, it sits competitively among lightweight, feature-rich 5.56 rifles. View product details and pricing

Who benefits most?

Casual shooters, three-gun competitors, and tactical-minded owners will appreciate the blend of a light handguard, stable stock platform, and the flexibility afforded by the 1:7 twist and threading. The 5.56 NATO cartridge remains an excellent balance of recoil, capacity, and ballistic performance for common defensive and sporting roles.
