  • The Longstrike Immortal kit is a drop in kit that transforms the Longstrike into a direct plunger blaster. Direct plunger systems greatly increase the amount of usable air volume while simultaneously eliminating the large amount of dead space found in the original reverse plunger. This translates into a huge increase in muzzle velocity even when compared to our old (now discontinued) Massacre kit. What sets our direct plunger system apart from blasters like the Retaliator is the static plunger body. We engineered our plunger body to dissipate the plunger’s impact across multiple surfaces within the shell, ensuring that the operating parts do not experience undue stress and impact from the powerful 7kg mainspring. Two springs are included with this kit, a 5kg spring for easy one handed priming and fast follow up shots, and a very powerful 7kg spring for maximum velocity.
