Before measuring, it’s important to note that J is only measuring with heavy bb’s, not with 0.2. This means that adjusting the hop-up for the best flight path is crucial for accurate measurements. It’s essential to ensure that the bb’s are able to travel with the proper trajectory for precise results. Therefore, take the time to calibrate the hop-up accordingly before conducting any measurements.
We recommend for you to use lithium grease or any thick grease on spring and spring guide.
If the Rapax sniper spring shoots too hot for your field, you can cut some of the coils without damaging the spring integrity as long as it is done properly. Instructions how to cut a spring are in video section here https://rapaxsprings.com/how-to-cut-airsoft-spring/
