The BOLT M is an HPA conversion kit engineered for bolt-action sniper rifles, delivering stealth, precision, and efficiency in one mechanical package.

Stay hidden with intrinsically quiet operation—no loud spring noise to give away your position. The spring-free design lets you cycle smoothly without breaking sight picture, keeping you locked on target for faster, more accurate follow-up shots.

Installation is straightforward with an innovative quick-change air attachment system that switches seamlessly between spring and HPA setups.
