The Angstadt Arms UDP-556 is a semi-automatic modern sporting rifle chambered in 5.56 NATO with a 16-inch barrel and 30-round capacity. It ships in black and is made in the USA.
The flared magwell speeds up magazine changes without requiring a precise index. A threaded bolt catch screw resists loosening under repeated cycling, and an upper tension screw adds stability to the upper receiver fit. The B5 Systems Type-23 grip has a texture and geometry that works for a range of hand sizes. The 16-inch barrel uses 4150 Chrome Moly steel with a 1:7 twist, which handles the full 5.56 NATO pressure spec and stabilizes heavier projectiles well.

AI-generated insights derived from customer reviews and discussions on popular gun-enthusiast forums.
The UDP-556 gets positive marks for its compact, light build and the reliability of the semi-auto action. Owners running it at the range find the 5.56 recoil easy to manage, and the build quality — materials and fit — holds up well in reviews. Accuracy at distance comes up often as a selling point.
The main criticisms are about value relative to competitors. Some buyers feel there are other rifles at a lower price point with similar specs, and a few note limited parts and accessory availability specific to this model. Ergonomics draw occasional comment too — some users would prefer a different stock profile or grip texture for longer sessions.
On balance, the reception is positive. The durability and reliability get more praise than the price gets criticism.
