Built on the AR-15 platform and made in the USA, this factory-marked AAR15 is chambered in .50 Beowulf and uses Alexander Arms' proprietary magazine interface for a 7+1 capacity. The upper is a slick-side configuration without a forward assist and includes an ejection-port cover. Barrel length is 16 inches with threading and is finished at the muzzle with the Alexander Arms Millennium ported compensator.
The free-float aluminum handguard provides M-LOK slots at the 3, 6, and 9 o'clock positions and rail segments at 12 o'clock; the top rail is not continuous from receiver to muzzle. A short vertical foregrip is mounted to the handguard. The upper receiver top is marked 'ALEX-A 50 BEO,' and the rifle is finished in matte black with no sights included.
Controls and internals are comprehensively upgraded. It features the Radian Weapons Raptor SD ambidextrous charging handle with a nickel boron finish and the Radian Weapons Talon 90-degree ambidextrous safety selector, also nickel boron coated. The Elftmann Tactical 3-Gun 2.5 lb drop-in trigger uses a straight, skeletonized shoe, secured by a KNS Gen JJ stainless anti-rotation/anti-walk pin set. Additional enhancements include the Phase 5 winter trigger guard, Phase 5 oversized magazine release button, a Magpul B.A.D. Lever bolt-catch extension, and the Strike Industries Tribus enhanced castle nut with extended end plate.
Furniture is configured for practical handling and readiness. The FAB Defense GL-MAG M4 Survival collapsible buttstock integrates a spare-magazine compartment and offers an approximate 12–15 inch length of pull from collapsed to extended. A rubberized finger-groove pistol grip completes the setup for a secure hold.
Two Alexander Arms/E-LANDER steel magazines are included, each marked '.50 BEOWULF' with the AA shield and 'Made in Israel' markings. The rifle's direct impingement system, threaded barrel with Millennium compensator, and ambidextrous control suite combine to deliver a well-sorted .50 Beowulf configuration.
