Why Builders Choose the AX556 (OD Green)

• True ambidextrous control layout: Mirrored mag release and bolt catch/release enable faster reloads, immediate lock-back, and rapid return-to-battery from either shoulder—ideal for barricades, vehicles, and dynamic stages.

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

• Ergonomics that matter: A flared magwell speeds insertions, the integral trigger guard provides glove clearance, and de-horned edges reduce hot spots and snagging on gear.

• Cerakote® ODG durability: Low-glare, solvent- and abrasion-resistant finish that blends with modern field palettes and pairs cleanly with black or FDE components.

• Builder-friendly details: Clean threading, precisely sized pin bores, and compatibility with common AR-15 parts streamline assembly and long-term service.

• Ready for premium parts: Plays perfectly with match triggers, duty-grade BCGs, and top-tier uppers in 5.56/.223 and other AR-15 cartridges.

Use Cases & Build Concepts

• Duty / defense rifle: Ambi layout simplifies manipulations around cover; pair with a free-float M-LOK® upper for white light + IR + sling integration.

• 3-Gun / 2-Gun competition: Faster, more consistent reloads and lock-backs; flared magwell and positive controls shave seconds on stage times.

• Left-handed shooters / training fleets: Identical manual of arms for every shooter reduces errors and speeds skill transfer.

• Suppressed general-purpose carbine: Ambi controls plus modern gas setups make for a versatile host that’s easy to run from either shoulder.

Pro Assembly Notes

1. Selector setup: The included Talon™ supports 45° (short throw) or 90° (MIL-style) — choose based on trigger and training preference.

2. Receiver extension: Torque to spec, use quality grease, and stake endplate if applicable.

3. Trigger pairing: Match the billet precision with a reputable single-stage or two-stage; verify safe/reset function before live fire.

4. Magazine fit: Test drop-free performance with your preferred aluminum and polymer mags; the flared magwell is tuned for speed.
