Upgrade Spring

This spring works great, really increased velocity without being overly hard to rack the slide and relatively easy to swap it out.

Great spring (a little strong)

This spring is great and powerful I am 15 and if I have the slightest bit of moisture on my hand it is hard to prime. I can do it but it is hard. I would recommend a 3D printed T pull for the Kronos with this upgrade spring in the gun. Otherwise great product.

More than offered

120-125. Nope I’m getting 140 using the same Chronograph. It pops. Prime is stronger but not bad with grip tape. The fun of the shot is incredible!
