- 25.06.2026 wrote:I bought this Guarder SP 170 spring for a high-power build. It's stiff, really stiff. Definitely not for stock gearboxes unless you've reinforced everything. Gives a serious FPS bump, but the pull is heavy. Quality feels top-notch, typical Guarder reliability. Only grab this if you know what you're doing and have upgraded internals.
