Wolverine Airsoft BOLT-M Hraith HPA Engine – Mechanical Sniper Conversion

Pure mechanical precision for bolt-action sniper platforms. The Wolverine Airsoft BOLT-M HPA Engine is a fully mechanical pneumatic conversion system designed to deliver exceptional consistency, smooth bolt operation, and reliable performance without the need for batteries or electronics.

Engineered for serious sniper players, the BOLT-M provides a highly efficient air system with adjustable performance characteristics and reduced mechanical stress compared to traditional high-power spring builds.

Mechanical HPA Operation

The BOLT-M operates using a purely mechanical pneumatic system. This eliminates electronic components while maintaining excellent shot-to-shot consistency and reliable performance in all weather conditions.

Smooth & Lightweight Bolt Pull

By replacing heavy spring tension with regulated air pressure, the BOLT-M significantly reduces cocking effort. This allows faster follow-up shots and improved comfort during long sniper engagements.

Adjustable FPS Performance

Players can fine-tune rifle performance using a compatible HPA regulator. This allows adjustment of muzzle energy to meet site limits and optimise trajectory for different BB weights and engagement distances.
