Whether you’re ringing steel at distance or dialing for a high-stakes hunt, this AICS mag keeps your rifle running smoothly so you can focus on wind calls—not malfunctions.


Why Choose an AICS-Pattern Magazine for .300 Win Mag?

  • Proven geometry = reliable feeding: AICS feed geometry is the benchmark for precision long-action magnums, providing smooth, nose-up presentation and strong control of the belt/body juncture typical of .300 Win Mag.

  • Long-action compatibility: Designed for AICS long-action footprints, so it integrates with popular chassis and stocks used for magnum builds.

  • Precision build quality: Robust body with precise feed lips and a controlled internal stack reduces tilt, drag, and nose-dive—helping you maintain a consistent bolt stroke in all positions.

  • Field-ready durability: Built to withstand dust, rain, and recoil cycles associated with magnum rounds, with a finish that resists corrosion and wear.

  • Range to mountain capable: From prone matches to alpine hunts, this magazine is purpose-built for the environments where .300 Win Mag excels.


Key Features at a Glance

  • Caliber: .300 Winchester Magnum (300 Win Mag)

  • Pattern: AICS long-action compatible (common precision chassis/stock footprint)

  • Body: Heavy-duty construction with tuned feed lips for consistent pickup

  • Follower: Anti-tilt design for reliable stack alignment

  • Spring: High-tension, corrosion-resistant spring for repeatable cycling

  • Finish: Wear- and corrosion-resistant exterior for hard field use

  • Capacity: Commonly available in 5- or 10-round variants (verify selected capacity for SKU 100015880)

  • Overall Length (OAL): Supports typical .300 Win Mag long-action cartridge lengths; check your rifle’s preferred COAL and magazine well specs

  • SKU: 100015880

Compatibility Tip: AICS-pattern magazines are used in many chassis systems and stocks. Verify fit with your specific action/chassis (e.g., MDT, KRG, XLR, MPA, and other AICS-footprint systems) and confirm bottom metal requirements for your rifle.


Performance Benefits You’ll Notice

  • Smoother bolt runs: Correct stack geometry and follower control help the round rise straight and true, supporting a clean chambering stroke—even in rapid follow-ups.

  • Improved positional reliability: Maintains consistent feed angle from barricade, prone, or steep field positions where magnum cartridges can be picky.

  • Consistent POI workups: When feeding is consistent, your load development and dope are easier to validate over long strings.

  • Confidence under recoil: Robust spring and body resist compression and lip spread that can lead to double feeds or nose dips over time.


Ideal Use Cases

  • Long-range precision with .300 Win Mag (competition practice, steel, and prone training)

  • Hunting where reliable follow-up shots matter—open country, timberline, and backcountry pursuits

  • Dope validation & chronograph work where consistent feeding supports consistent data collection

  • Duty/LE precision rifles built on AICS-pattern systems (where applicable)


Setup & Fit Checklist

  1. Confirm footprint: Your stock/chassis should specify AICS long-action compatibility.

  2. Check bottom metal: Ensure your DBM (detachable box magazine) accepts AICS-pattern LA mags.

  3. Verify COAL: If you handload, measure your cartridge overall length against the internal mag length to ensure proper clearance.

  4. Function test: Cycle dummy rounds to verify clean pickup, bolt over-ride clearance, and positive last-round presentation.


Maintenance Tips

  • Keep it clean: Brush out dust, grit, and unburned powder from the body and follower path after range or field use.

  • Inspect feed lips: Periodically check for bends or spread; proper lip tension is key to controlled presentation.

  • Light lube (optional): A dry film or very light protectant can help resist corrosion without attracting debris.

  • Rotate mags: If stored loaded for long periods, rotate magazines to preserve spring life.

Frequently Asked Questions

Q: Will this fit non-AICS rifles?
A: Use only with AICS-pattern long-action systems or bottom metal designed for AICS magazines. It won’t fit proprietary magazine wells.

Q: Can I run other magnum cartridges?
A: This magazine is optimized for .300 Win Mag. Some AICS LA mags feed other belted magnums, but always verify reliability and COAL for your cartridge.

Q: Is this compatible with CIP-length loads?
A: Internal length support varies. Check the mag’s internal OAL against your chosen CIP/handload length and your action’s feed path.

Q: Do I need to tune feed lips?
A: Most users do not need to adjust anything. If you’re running very long bullets or unique profiles, minor tuning by a qualified gunsmith may help.

Q: How many mags should I carry?
A: For matches or backcountry hunts, many shooters carry two to three—one in the rifle and a spare or two in a pouch for quick reloads.
