Compact Bullpup Design with a Full 16" Barrel
The AUG A3 M2’s bullpup layout places the action and magazine behind the trigger, giving you rifle barrel performance in a much shorter overall package:
The result is a rifle that feels fast and maneuverable in tight spaces—vehicles, hallways, blinds—while still giving you the ballistics of a full-length 16" barrel.
.300 AAC Blackout – Suppressor-Friendly, Versatile Caliber
This AUG A3 M2 variant is chambered in .300 AAC Blackout, a cartridge specifically designed for short and suppressed platforms: Palmetto State Armory+2Classic Firearms+2
Optimized for both supersonic and subsonic loads, making it excellent for suppressed or unsuppressed use.
Delivers excellent performance from 16" barrels, with hard-hitting energy and good barrier performance for defensive and professional roles.
Well suited for home defense, hogs and predators, and tactical training, especially when paired with modern optics and quality ammunition.
If you like the AUG platform but want a caliber tailored for suppressed shooting and modern defensive use, the 300 BLK AUG A3 M2 hits a sweet spot.
Extended Top Rail for Optics and Accessories
This specific configuration features an extended Picatinny optics rail, giving you far more real estate than the original AUG integrated optic: Range USA+3GrabAGun+3EuroOptic+3
Run LPVOs, red dots, magnifiers, backup irons, and thermal/night optics in whatever combination your mission demands.
Extra rail length makes it easy to set proper eye relief and co-witness BUIS if desired.
The flat-top rail keeps the gun flexible for everything from home defense to night hunting and patrol optics setups.
For shooters who want the legendary AUG handling with modern optics flexibility, the extended rail is a major upgrade.

The AUG A3 M2 uses a rugged, weather-resistant synthetic stock with built-in features designed for serious use: Arnzen Arms+3EuroOptic+3Range USA+3
Stock: Durable black synthetic bullpup stock, built to handle hard field use and rough environments.
