5KG OOD Longshot Spring

Great spring. Hits harder than stock but not so hard that it hits too hard to use. Fast shipping! Great product. A++++++++

After installing the spring there’s about a 1/8in overlap between mags and the dart chamber. Did anyone else run into this

After reinforcing the stock extension, this spring weight is perfect for keeping the bolt action prime on my longshot. I also didn't need to change the catch or its spring. With a 24.8 CM short dart barrel, I'm getting well over 130 FPS (testing w/ chronobarrel and accounting for dart length.)

I had no idea the fps you can get with this spring and brass!
