£201.50
The Wolverine BOLT M HPA Engine for the Silverback SRS transforms one of airsoft’s finest bolt-action platforms into a regulated HPA precision instrument — mechanically actuated, near-silent, and devastatingly consistent.
Wolverine Airsoft BOLT M HPA Engine – Silverback SRS
The Silverback SRS is already one of the finest bolt-action platforms in airsoft — the Wolverine BOLT M takes it to a new level. Designed specifically for the SRS platform, this mechanically actuated HPA engine replaces the factory cylinder system with regulated pneumatic power, delivering near-perfect shot-to-shot velocity consistency that no spring setup can reliably achieve at range.
The BOLT M operates entirely via your bolt cycle with no electronics or battery required. Every shot is driven by clean, regulated HPA, giving remarkably quiet operation and genuine consistency at 60+ metres. The “M” designation indicates the medium cylinder variant, matched to the SRS’s geometry. It’s the natural evolution for SRS owners who have reached the ceiling of spring upgrades.
