SeeFox FX Impact M3, M4 High Power Tuning Tungsten Hammer 32gm And Spring Kit is an innovative design for extreme tuning of FX Impact M3 and M4 rifles to achieve very high performance for heavy slugs – consistency, velocity and efficiency.
This kit includes a heavy tungsten hammer 32gm along with three different configurations of heavy duty hammer springs, a valve return spring and a peek rod spring guide.
The Tungsten hammer is 32gm, this single unit hammer configuration that replaces the two component configurations – Configuration 1. factory hammer 18gm + factory hammer weight 6gm = 24gm OR factory hammer 18gm + tungsten hammer weight of 13gm = 31gm. This innovative design helps to minimize the moving components and makes the valve opening action more consistent and efficient for heavy slugs at high velocity.
Three unique spring configuration options to decide based on the desired performance. Gold Spring – 54mm length and 1.4mm wire diameter, more travel / low hit. Titanium Spring – 52.5mm length and 1.5mm wire diameter for moderate travel / medium hit. Silver Spring – 51mm length and 1.6mm diameter for less travel / high hit. All three spring designs are proven for consistent and efficient performance.
Custom valve return spring in black for the optimum valve return action, best advised along with the use of the other components in the kit.
Peek rod spring guide to provide effective and smooth hammer action along with other components.
