Having issues achieving low pressure ranges on your Polarstar? This spring is easier for the engine to compress, alleviating any low pressure issues which could keep the nozzle or poppet from cycling. Additionally, this can help with guns not cycling in colder conditions, as well as periodic dead shots. Shooting at lower PSI levels is ideal for long barrel DMR setups, quieting your gun, and achieving fantastic air efficiency. The flip side of this, is you will not be able to hit the extreme high rates of fire at the upper reaches of the Fusion Engine limits.
Contains one low pressure spring, works for either the nozzle or poppet, requiring under half the force to compress vs the stock springs. Color may vary by batch.
