Purchased the 133 FPS spring and unfortunately darts do not always exit the barrel which causes frequent jams. Going to try the next step up to see if it’s a better compromise. The stock spring works perfectly but just hits so hard!!
This will be nice to lower the FPS for HvZ and other low power games.

Firstly the bk2s is a fantastic blaster, picky with well used darts but fires like a beast, the downgrade spring I ordered from out of darts works a treat bringing it down to the FPS cap of my locals and worked flawlessly. I 100% recommend both the spring and out of darts themselves. They shipped very fast and kept me up to date with my order. I will definitely order from them again.
