Why Shooters Choose the RESOLUTE Mk4 in .22 ARC

• .22 ARC performance advantage: Purpose-built to push high-BC .224 bullets fast, .22 ARC delivers flatter flight paths and superior wind resistance compared to legacy .223 loads—ideal for coyotes, prairie dogs, and practical rifle training.

• 16.1" “do-most” barrel length: Maximizes velocity from an AR-length platform while keeping the rifle compact for vehicles, blinds, and quick position changes.

• Free-float M-LOK® handguard: Add bipods, barricade stops, tripods, and lights without affecting barrel harmonics—tune the rifle to your mission.

• AR-15 familiarity: Standard controls, intuitive manual of arms, and broad parts compatibility for easy upgrades and at-home maintenance.

• Optics-ready top rail: Mount an LPVO, mid-power scope, or thermal/red dot combo and get to work; plenty of rail space for backup sights.

• Charcoal Green finish: Durable, low-glare colorway that looks as good on the bench as it does on the back 40.

Field & Range Performance

• Wind-smart hits: Pair .22 ARC with sleek 62–75+ gr bullets and watch holds shrink at distance. Less drift means cleaner calls and higher hit percentages in gusty country.

• Stay on glass: Mild recoil lets you spot impacts and correct quickly—perfect for coyote stands and high-volume prairie dog towns.

• Position-friendly build: The free-float handguard, balanced barrel, and AR ergonomics settle naturally on bipods, bags, tripods, or a backpack rest.

• Threaded versatility: Add a muzzle brake to flatten recoil or a suppressor (where legal) for comfort and better animal management—just reconfirm zero after changes.

Setup Tips (Get the Most from .22 ARC)

1. Optic pairing: A 2-10x or 3-15x scope with reliable tracking is a sweet spot; LPVOs work for calling setups. Consider a canted base/offset dot if you shoot near-to-far.

2. Ammo testing: Try multiple bullet weights and brands; chronograph to build true DOPE for your density altitude.

3. Mag discipline: Dedicate mags to .22 ARC to avoid mix-ups with other Grendel/ARC cartridges; label capacities for quick ID.

4. Support gear: Add an M-LOK bipod or ARCA adapter for tripod/saddle use. A QD sling helps carry hands-free across fields.

5. Torque & witness: Torque ring/base screws to spec and mark them; verify after travel and high round counts.

Who It’s For

• Predator & varmint hunters who need flat trajectories, ethical terminal performance, and quick follow-ups.

• Ranch & property owners wanting a precise, reliable AR for pests across open ground.

• Practical rifle trainers focused on wind reading and hold discipline with low recoil and long barrel life.

• Tinkerers & builders who prefer AR modularity with a modern cartridge that truly stretches the distance.

Care & Maintenance

• Keep it smooth: Clean the chamber, bore, and BCG; lightly lube bearing surfaces.

• Protect the crown/threads: Cap or device installed—keep threads clean and re-check timing/torque.

• Hardware once-over: Handguard, gas system, optic, and muzzle device fasteners should be checked after flights or bumpy ranch roads.
