The Core: CM7S Action – Full PVD Coated

The CM7S action is designed for hunting use, providing the ruggedness needed for the field, but it can also be used for competition, where speed and smoothness are paramount. It is a steel action with a Remington 700-style footprint, ensuring that your investment is compatible with the world’s most popular aftermarket support ecosystem.

The CM7S has several features that factory actions lack, making it the professional choice for those who demand more from their gear:

• Based on the classic Remington 700 footprint with a 3-lug design, this foundation allows for a 60-degree throw, providing massive clearance for optics and enabling lightning-fast follow-up shots.

• M16 style extractor: Known for its legendary reliability, this extractor ensures positive ejection in the most demanding conditions.

• One-piece bolt – 0.718″ Bolt Body DIA: Our heavy-duty, spiral fluted bolt reduces “bolt-flick” and enhances the overall rigidity of the system.

• Wire EDM raceways: We use Electrical Discharge Machining for more uniform tolerances and smoother cycling than traditional milling can offer.

• Full PVD coating: For more corrosion protection and smoother operation, the entire action is PVD treated, resulting in a surface that feels like glass on glass.

Advanced Action Specifications:

• Pinned 20 MOA Picatinny Rail: Ready for long-range holds out of the box.

• Large ejection port and cut-out: Optimized for a light-weight action body, bringing the total action weight to just 25oz.
