Fortmeier ARCA/RRS Mount Adapter for Bipod
The Fortmeier ARCA/RRS mount adapter brings your Fortmeier bipod to the ARCA-Swiss rail system, the standard for modern long-range precision rifles. This adapter enables mounting your bipod on weapons with ARCA rails or RRS (Really Right Stuff) compatible systems, giving you access to the most versatile mounting system in precision shooting.
The ARCA-Swiss System
ARCA-Swiss is a standardized rail system originally developed for professional photography but has since become the standard in precision long-range shooting. The system offers unique advantages:
Full-Length Adjustability: Unlike Picatinny where you're bound to specific slots, with ARCA you can place your bipod anywhere along the full length of the rail. This gives infinite possibilities for finding the perfect balance point.
Stronger Connection: The ARCA clamping system provides a robust, vibration-free connection that maintains its grip even with heavy calibers.
Smooth Profile: ARCA rails have a sleek, streamlined profile without protruding teeth like Picatinny, resulting in a cleaner look and fewer snag points.
Universal Compatibility: Virtually all modern precision accessories (tripods, bag riders, barricade stops) use ARCA as standard.
RRS Compatibility
The adapter is fully compatible with Really Right Stuff (RRS) rails and accessories. RRS is a premium brand in the photography and shooting industry known for unmatched quality. Through this compatibility, you can combine your Fortmeier bipod with:
- RRS tripod heads and quick-release systems
- RRS rifle rails and chassis components
- Area 419 ARCA accessories
- MDT ARCA rails
- Other premium ARCA-compatible systems
Ideal for Long Range Precision
The ARCA adapter is the preferred solution for serious long-range shooters for multiple reasons:
ELR (Extreme Long Range): At distances of 1500+ meters, a stable platform is essential. The ARCA adapter combined with a Fortmeier bipod provides the stability needed for consistent impacts.
F-Class Competitions: In F-Class Open, shooting is often done from bipods. The ability to position the bipod exactly for optimal balance is crucial for high scores.
King of 2 Miles: At ultra-long distances (3500+ yards), every millimeter of movement is visible in your reticle. The solid ARCA connection minimizes micro-movements.
Tactical Precision: For tactical applications where quick setup is necessary and repeatability is essential, ARCA offers the speed and reliability you need.
Mounting and Positioning
The Fortmeier ARCA adapter can be mounted at any position along the ARCA rail. This is a huge advantage over systems that can only be attached at the end.
Balance Optimization: By sliding the bipod forward or backward, you can perfectly tune your setup's center of gravity. This is especially important with heavy calibers or when adding or removing different accessories (like suppressors).
Position Independent: Whether shooting prone, from a bag, or from a barricade, you can always place the bipod in the optimal position.
Quick Adjustments: With a single turn of the clamp screw, you loosen the adapter, slide it to the desired position, and secure it again. This is considerably faster than dismounting and remounting a Picatinny mount.
Clamping Force and Safety
The ARCA clamp of this adapter features adjustable tension that you can tune to your weapon's weight and personal preference. Proper adjustment ensures that:
- The bipod stays firmly seated during shooting
- You can still move the bipod when desired
- No damage occurs to the ARCA rail
- The connection doesn't loosen from recoil
Recommended clamping force is between 30-40 inch-pounds, depending on your specific setup. An overly tight clamp can damage the rail, while an overly loose clamp can cause shifting during shooting.
Compatibility with Chassis Systems
The ARCA adapter works excellently with modern chassis systems that integrate ARCA rails:
MDT Chassis: ACC, ESS, LSS-XL, and other MDT chassis have native ARCA rails on the bottom.
KRG Chassis: Whiskey-3, X-ray, and Bravo chassis can be equipped with ARCA rails.
MPA Chassis: Master Piece Arms chassis often have ARCA compatibility.
Foundation Stocks: The popular Foundation Centurion and Genesis stocks have integrated ARCA rails.
Custom Chassis: Virtually every modern custom chassis can be fitted with ARCA rails.
Multi-Purpose Use
A major advantage of ARCA is that you can fulfill multiple functions with one adapter. Thanks to the universal ARCA standard, you can:
Quick Switch Between Accessories: Easily swap between your Fortmeier bipod, a tripod, or other ARCA accessories without needing different adapters.
Combine with Other ARCA Gear: Use the same rail for bag riders, barricade stops, or leveling indicators.
Future-Proof Investment: ARCA is increasingly becoming the industry standard, meaning your investment remains relevant for future upgrades.
Material and Construction
Manufactured from high-quality anodized aluminum with precision CNC machining. Fortmeier's German engineering guarantees perfect tolerances and flawless fit.
The adapter has a low profile that doesn't unnecessarily enlarge your weapon's silhouette. The matte black finish matches most modern precision rifles and prevents reflections that could reveal your position.
