70° Deep V Piston Head for M17 and M18 GBB Replicas VFC - SIG AIR SP SYSTEM T8

The 70° Deep V SP System T8 piston head for VFC and SIG AIR M17/M18 GBB replicas is an internal upgrade part designed specifically for the family of GBB replicas based on the SIG P320 platform. Its 70-degree hardness rubber construction and "Deep V" profile set it apart from a standard piston head: this design generates a sonic effect during gas compression, enhancing sealing at the precise moment of expansion and ensuring a more stable gas release with each cycle.

Compatible with the P320, M17, M18, X-Carry, SA320, and Peacekeeper series from SIG AIR and VFC, this part is intended for players who want to optimize the gas flow efficiency of their pistol replica without altering its external structure. It improves the consistency of the GBB cycle.

This Deep V piston head is therefore an ideal upgrade part for your GBB airsoft pistol.
