Specna Arms 90° Tuning Kit for SA-S02/S03

The Specna Arms 90° Tuning Kit for SA-S02/S03 & VSR-10 is a complete upgrade kit for spring-powered sniper replicas. The set consists of a 90° trigger unit, an aluminium piston and an aluminium spring guide, which reinforce the internal drive mechanism and make it suitable for more powerful configurations.

This tuning kit has been developed for Specna Arms SA-S02, SA-S03 and compatible VSR-10 replicas.

Complete upgrade for sniper replicas

The kit contains all the essential parts for upgrading the pull rod and spring assembly:

• Aluminium piston
• Aluminium spring guide
• 90° triggerunit

By replacing these parts as a complete set, the components will fit together perfectly.

Robust 90° trigger unit

The trigger unit features a metal housing with hardened steel internal components, including the piston stopper and trigger sear. Thanks to the 90° sear design, forces are distributed more efficiently than with a standard trigger mechanism.

As a result, the trigger unit is better able to withstand powerful springs and prolonged use.

Aluminium piston en spring guide

The supplied piston and spring guide are made from lightweight aluminium. This results in a strong and durable construction without adding any unnecessary extra weight to the internal drive mechanism.

The combination of these components ensures that the sniper replica operates reliably.

Practical insights

A 90° tuning kit is widely used in sniper replicas fitted with heavier springs. The straight engagement of the 90° trigger reduces the load on the sears and increases the reliability of the entire trigger mechanism. Replacing the piston, spring guide and trigger unit at the same time results in a well-coordinated upgrade.
