ANGSTADT ARMS UDP-556

Design and ergonomics

Standard fitment includes a B5 Systems SopMod Stock and a B5 Type-23 grip, giving immediate comfort and compatibility with a wide range of aftermarket accessories.

Barrel, twist rate, and muzzle options

Accuracy-forward barrel construction

At the heart of the build is a 16″ chrome moly barrel with a 1:7 twist, chambered in 5.56 NATO. That 1:7 twist stabilizes heavier bullets commonly used for extended-range and defensive loads, while the chrome moly construction balances durability and heat management. The barrel is threaded to 1/2×24, allowing easy installation of a variety of muzzle devices or suppressors compatible with that common thread pitch.

Practical loadout and value

The rifle ships with one 30-round magazine and delivers a ready-to-run package for $1471.99. For shooters who prefer a minimal parts list and a complete platform for duty or competition, the UDP-556 removes guesswork by pairing quality furniture with a free-floated barrel and modern M-LOK attachment points.
