The AUG/A3 M1 platform delivers a compact bullpup form factor with an approximate overall length of 31 inches (factory spec) while retaining a full-length 20 inch barrel. This example features an alloy receiver, AUG-pattern polymer stock and magazines, and last-round bolt hold open.
The 20 inch barrel is quick-detach and part of the AUG quick-change system with a folding barrel grip for removal. It is cold hammer forged, chrome-lined, and threaded, and it comes fitted with a multi-prong flash suppressor. The rifle is chambered in 5.56mm NATO and operates via a gas-operated, short-stroke piston with a two-position adjustable gas regulator.
The integrated 1.5x carry-handle optic includes a donut ring reticle with a center aiming point and external elevation and windage turrets. For configuration flexibility, the OEM long top Picatinny rail module is included and can be installed in place of the integrated optic via the AUG modular top assembly system.
A non-factory enlarged charging handle is installed for easier manipulation, and the original OEM charging handle is included. Capacity is 42+1 with the extended magazine, and the package includes both a 42-round and a 30-round AUG-pattern translucent magazine. Receiver and barrel markings include "STEYR ARMS, INC. BESSEMER, AL" on the receiver and "5.56x45" on the barrel block.
