Sidestrike & Firestrike 7kg Upgrade Spring

A 7kg upgrade spring for your Zombie Strike Side Strike and the Elite Firestrike.

Note:This spring will fit the Strongarm but we don't recommend that you try. We have 7 or 8 dead ones here in the office as a result of testing it and the piston arm breaking at the interface with the slide. If you're still unsure, see Question 4 of our FAQs page.
