Cutting the LV10 Mainsprings...

[striker]

Alright, I've got my LV10 tuned and it's working great, but the impact force is still a bit high. I tried putting in the other mainsprings and turning up the velocity, and that worked, but the sear didn't reset quick enough, limiting my bps to about 5. So, I'm now entertaining the idea of cutting one of my LV 10 mainprings to make the impact softer, but not too strong of a mainspring so it slows down the bps. Any help?

I took my longest spring, which I couldn't get to fire reliably under 320fps or so, and cut it down so that the overall length is right in between the short and med springs. This worked well for me, and I have yet to use either of my other springs.

I really don't recommend cutting the springs because it weakens them. The best thing to do is use the short spring and a really loose carrier o-ring fit. The ideal fit is to be able to hold the bolt at the top of the PT and drop it and it should come down and hit the bumper under its own weight. Each o-ring is different, so it takes a bit of tweaking to get it right.

FWIW- I use the gold spring in all of my guns. As long as the feed system can keep up, you shouldn't have a problem. I use an 18V warp, so...

Black, is it normal for the springs to compress after use? I used just my short spring for the longest time, and I noticed a few months ago that the spring wasn't sticking much past the bolt anymore. That is when I decided to replace it with the cut spring. I never had any chopping problems with the gold spring, however. Oh, and that cut spring seems to be holding up pretty well.

Yes, the spring will shorten over time and with use. Just sitting in the gun it's compressed and using it adds to the wear of the spring. When it becomes shorter than the tip of the bolt, it's time for a replacement.
