Cutting ang modifying a sniper spring.

[Cyclops]

SD97 sniper gun and placed a new spring set up. Currently chronoes at 557 to 566 fps average was 563 (20 shots). I was thinking of starting to cut 1 coil at a time to see if I can get it to 540 to 545 range. After cutting it, heating it up to place it closer to the next coil and was thinking about using sodder to bond them together (thinking it might make it stronger). Good idea? Option of buying a different spring is out of the question. Just looking for ways to drop it about 20 fps so I have some wiggle room on the fps. Thoughts, concerns?

Fragmented sodder chunks a flying, you a crying?

Cutting the wires will reduce spring length and may cause issues. Just replace the spring.

Don't do it!

Leave it compressed a couple of weeks. If that doesn't work file a small groove in the oring to make it leak.

I finally heard the best reason not to cut or heat springs ever. It is because they specially made and when you modify them with heat or by cutting they lose their integrity.

I'm never in favor of intentionally causing FPS loss through compression seal loss. Couldn't the force cause more loss of compression as it gets used more and more? (o-ring tearing, blowout). Can't really control how much fps you loss. same with spring compressing.

I also wouldn't leave the spring compressed as it puts stress on your trigger sear and honestly in those china boxes they aren't always the tightest tolerances.

I'm a conservative. I say just replace the spring. You know how to tear into the rifle already and the money for a spring isn't the issue for you. Just replace it. That new spring was designed specifically to perform at a lower fps.

IMO.

but what phiz offered is certainly an alternative.

I'm afraid to disagree with Phizs' massive brain, think he'll pull a scanners, and make my nose bleed.

But a spring is only like $15? That's way cheaper than any of the work you'd have to do if shit went bad.

The problem is the spring is a ASR spring which is smaller then most springs Finding the right size as in diameter is hard to find and fit in the piston. Also local stores don't carry just the spring of that diameter. That's why I'm tying to modify this set up so I can use it this weekend. Hopefully....

It is very difficult to find the smaller diameter spring rifle springs. They also usually go in 50-100 FPS increments, not the 20 that he wants to lose.

If leaving it compressed is outside your comfort range, I'd recommend shooting it like 200 times.
