The Smith & Wesson Service Kit is a compact maintenance set designed to keep compatible models operating reliably. The kit includes a selection of O-rings, washers (small and large), and a replacement spring, covering the most commonly worn sealing and tension components. These parts help restore proper gas sealing, stabilize internal movement, and ensure consistent function over time.

Ideal for routine servicing or replacing aged components, this kit supports long-term durability and reduces performance inconsistencies caused by worn seals. All included items are direct-fit replacements, allowing easy installation without modification. This makes the Service Kit a practical accessory for owners who want to maintain optimal operation and extend the lifespan of their airgun.
