MCAR CNC Valve Pin

BinTac MCAR CNC Valve Pin: Built for Pressure

In the world of high-powered airguns, consistency is king, but durability is the kingdom. Stock cast valve pins are notorious for failing under the stress of high-output tuning, leading to leaks, erratic velocity, or catastrophic failure during a hunt. The BinTac MCAR CNC Valve Pin is the definitive solution—engineered not just to replace the factory part, but to outperform it in every metric.

Precision Engineering

Unlike mass-produced stamped or cast components, this valve pin is CNC machined to aerospace-grade tolerances. This ensures a perfect concentric fit within the valve body, eliminating the “wobble” that causes seal wear and air leaks. The precise geometry allows for a cleaner “crack” of the valve, delivering a crisp, repeatable pulse of air behind every slug.

Heavy-Duty Durability

Whether you are pushing slugs for extreme long-range benchrest or need confident stopping power for hunting, your valve pin takes a beating. The BinTac CNC pin is crafted from hardened high-tensile steel (often treated/coated for reduced friction). It is designed to withstand heavy hammer spring tension and high regulator set pressures without bending, snapping, or mushrooming at the impact point.

Key Features & Benefits

• Superior Airflow: The streamlined profile reduces turbulence as air passes through the valve, contributing to slight velocity gains and improved efficiency.
• Rugged Reliability: Specifically heat-treated to resist deformation, ensuring your rifle stays operational when it counts.
• Perfect Sealing: Precision manufacturing ensures the pin seats perfectly against the valve seal every time, solving common slow-leak issues.
• Direct Drop-In: No machining or complex modification required. Designed as a 1:1 fit for MCAR and compatible AEA high-power platforms.
