Item # 158084 Style STY-AUGM1MUDEXT UPC 688218739464 Condition New Manufacturer [Steyr Arms](https://www.kygunco.com/brand/steyr-arms) Model AUG M1 Hand Right Hand Finish Black Round Capacity 30 Caliber 5.56 NATO, 223 Rem Action Semi-Auto Barrel Length 16.4 in ### Steyr Arms AUG A3 M1 16" 5.56 Mud w/ Extended Rail The iconic bullpup-style Steyr AUG has been one of the most recognizable rifles in the world since its adoption by the Austrian army in 1977 and is now available for civilian use as the Steyr AUG A3 M1, a semi-convertible ambidextrous rifle platform with an adjustable short-stroke, gas-piston operation chambered for 5.56x45mm (.223 Remington) ammunition in stock 10-, 30- or 42-round magazines. The multi-configurable M1 variant of the AUG A3 platform is the latest generation of the venerated bullpup platform. Utilizing an optics attachment platform similar to the rare and much-sought-after AUG A2, the AUG A3 M1 is available from the factory with an Extended Rail, but optional Short-Rails, High-Rails, 1.5X or 3X Optics will ship separately. The AUG A3 M1 Optics version has a more traditional AUG scope tube with exceptionally bright and clear optical elements, modernized with the addition of three Picatinny rail sections to accommodate accessories like a close-quarters holographic sight. With 16 numbered slots, the High-Rail version was designed to accommodate the widest range of optic choices, and the 11-slot Short-Rail version was designed for use with a reflex sight or a longer-eye relief optic. The rail and optics platforms on all three AUG A3 M1 versions are interchangeable via the three base screws that thread from the underside of the top of the receiver. The AUG A3 M1 boasts an overall length of just 28.15 inches, including its 16-inch heavy barrel, making it at least 8 inches shorter than an M4 carbine with a comparable-length barrel. The short-stroke gas-piston operation of the AUG runs exceptionally cleaner by nature because all of the operational exhaust gas vents out of the front of the rifle. The AUG's matching, yet opposed, stainless steel operation and guide rods affixed to the bolt carrier glide effortlessly inside the receiver for unparalleled smoothness in operation as well as exceptional reliability. Dual gas-adjustment settings ensure its operation, even with the dirtiest ammunition and in adverse conditions. The AUG A3 M1 has all the classic features and benefits that established it as the pinnacle of modern rifle design, including expedited disassembly as well as simple conversion to left-hand operation, which requires replacement of the standard bolt with the optional left-eject bolt and swapping the ejection-port cover. It also features a quick-change barrel with a collapsible forward grip as well as a two-position cross-bolt safety that locks the trigger. The receiver was also updated to replace the permanently affixed front sling swivel with a VLTOR Quick-Disconnect Sling Swivel, which makes two-point sling attachment or removal extremely fast and easy, and users of single-point slings can remove the front sling swivel entirely, if they so desire. The AUG A3 M1 stock, cocking piece and forward grip are made of highly durable synthetic and are available in Black, Green, Mud and White colors. The rifle is available in either the standard version that accepts genuine Steyr AUG magazines or as a NATO version that accepts standard STANAG (AR) magazines. **SPECIFICATIONS** - Model: Steyr AUG A3 M1 - Purpose: Target shooting, military & law enforcement, multi-gun competition - Manufacturer: Steyr Arms USA, Bessemer, AL 35022 - Operation: Adjustable, short-stroke, gas-piston, semi-automatic - Magazine type/capacity: Polymer double-stack detachable box/30 rounds (10- and 42-round avail.) - Receiver material: Hard Eloxal-coated aircraft aluminum - Caliber: 5.56x45mm (.223 Remmington) - Barrel: 16.375-inch mannox-lined (nitride) CHF barrel (18.375 inches with muzzle brake) - Rifling: 6 grooves, 1:9 RH Twist - Sights: Short 11-slot rail, High 16-slot rail, 1.5X optic or 3X optic - Safety: Two-position trigger-blocking - Trigger type: Single-stage - Pull weight: 9 pounds, 8 ounces - Stock material/type: White Black, OD Green or MUD synthetic/bullpup - Length of pull: 15 inches - Drop at comb: 0.435 inch (Short rail), 0.820 inch (High rail), 1.945 inches (Optic) - Drop at heel: None - Recoil pad: Elastomer; 0.3-inch thick - Sling swivels: Two (front QD, rear reversible) - Pistol grip: Integral - Checkering: None - Weight, empty: 7.7 pounds (Short Rail), 7.8 pounds (High Rail), 8.8 pounds (Optic) - Overall length: 28.15 inches - Included accessories: Owner's manual and one 30-round magazine. ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
