Why the AX556 Is the Lower Serious Builders Choose

• Fully ambidextrous controls: Mirrored mag release and bolt catch/release enable fast reloads and immediate action from either shoulder—ideal for barricades, vehicles, and dynamic stages.

• Billet strength & precision: 7075-T6 billet construction yields tighter tolerances, exceptional rigidity, and a refined fit with premium uppers and triggers.

• Upgraded ergonomics that matter: Flared magwell speeds insertions; integral trigger guard provides glove clearance; generous radiusing removes hotspots without snag points.

• Cerakote® FDE durability: Low-glare, solvent- and abrasion-resistant finish that blends perfectly with FDE or black furniture and accessories.

• Builder-friendly details: Precisely cut pin bores, anti-rotation considerations for the safety, and clean threading reduce assembly friction and keep your project on schedule.

• Ready for premium parts: Plays perfectly with match triggers, duty-grade BCGs, and high-end uppers in 5.56/.223 and other AR-15 pattern calibers.
