Feed your BR rifle the way it deserves.

Why Precision Shooters Choose the MDT 6BR 12-Round Mag
Optimized for 6BR Geometry: Internal shaping and follower design support the short, wide 6BR case for positive cartridge control and reduced nose-dive.
Competition-Ready Capacity: 12 rounds keeps you on the clock with fewer mag changes—perfect for PRS/NRL-style stages and long strings from awkward positions.
AICS Short-Action Compatible: Drops into most AICS-pattern chassis and bottom metals for a plug-and-play upgrade to your BR-based rifle.
Durable Metal Body: A rigid, corrosion-resistant black-finished steel/aluminum* body stands up to drops, barricade abuse, dust, and rain.
Smooth, Consistent Feeding: Anti-tilt follower and tuned spring tension provide dependable pickup—even on the last round.
*Material spec may vary by production; MDT uses robust metal construction across this series.

Note: Overall length and bullet profile influence reliability. Always confirm COAL and feeding in your rifle before match or field use.
Compatibility & Fit Guidance
Chassis/Bottom Metals: Designed for AICS-pattern short action systems. Confirm latch/catch height and inlet on your rifle.
Cartridge Variants: Optimized for 6BR. Many shooters successfully use BR-based rounds (e.g., 6BRA, 6 Dasher) with magazines designed for 6BR; verify function and COAL in your setup.
Not for .308-Based SA: This mag is tailored to BR geometry; .308/6.5 CM rounds require their respective AICS-pattern magazines.
Feed-Ramp/Action Tolerance: Action timing and ramp shape vary—test with your bolt speed and preferred ammo for best results.
Real-World Benefits
Run the Stage, Not the Clock: 12-round capacity means fewer reloads and more focus on wind and position building.
Less Fumbling, More Flow: BR-optimized stack and follower help present rounds at a consistent angle for clean chambering from prone or barricades.
Built for Abuse: Metal body and black finish resist dents and corrosion through travel, rain, and dusty match days.
Easy Service: Pop the floorplate to clear grit and keep the follower gliding smoothly.
Ideal Use Cases
PRS/NRL & Club Matches: High-capacity, BR-friendly feeding when every second and every point count.
Zeroing & Load Development: Long strings from the bench or prone without constant reloading.
Trainer Rifles: Pair with a BR-based trainer for inexpensive, recoil-friendly practice that mirrors match workflow.
Setup & Function Checklist
Confirm AICS Pattern: Ensure your chassis/bottom metal is AICS short action compatible.
Set COAL: Check your longest intended load for free movement and correct presentation.
Cycle by Hand: With the rifle unloaded, verify pickup/ejection from a full and partial stack.
Live-Fire Validate: Prove feeding at match pace from prone and barricades before match day.
Witness Mark: Add small marks to note feed-lip position or floorplate orientation after tuning/cleaning.
Care & Maintenance
Field Strip: Remove floorplate, spring, and follower to wipe dust and debris.
Light Protectant Only: Avoid heavy oils that trap grit—use a dry film or very light protectant.
Inspect Feed Lips: After drops or impacts, check for bends; carefully dress if needed.
Spring Health: Replace if you notice sluggish feeding or inconsistent last-round pickup.

Frequently Asked Questions
Q: Will this work with 6BRA or 6 Dasher?
A: Many shooters run BR-derived cartridges in magazines designed for 6BR with excellent results, but you must verify COAL and feeding in your specific action and setup.
Q: Is the magazine polymer or metal?
A: This MDT model uses a metal body with a protective black finish for strength and durability.
Q: Do I need to tune the feed lips?
A: Most rifles run these magazines out of the box. If issues arise, check rifle timing, mag catch height, and ammo COAL before making minor feed-lip adjustments.
Q: Will it fit my non-AICS bottom metal?
A: This magazine is AICS-pattern. If your rifle does not accept AICS magazines, you’ll need compatible bottom metal or a different magazine type.
