      Perfectly working, a good quality piece for overjoule gearboxes, this has a nice finish/coating.
      I used it on a 1.35j gearbox and made it 0.83j, next time I'll try a 95 or a 100 of the same series.

      I have used other brands springs before and there was a lot of variance that made it pretty much impossible to predict what any 1 spring was gonna do power wise, which was extremely annoying as it meant taking a replica apart lots of times to chrono different ones.
      These and consistent, the packaging is clear about the power level, and the price is good.

      Consistent Performance
      I’ve used this spring in various scenarios, and it has consistently delivered excellent performance.

      Put this in my Arcturus AT-AK12K-PE and it now shoot at exactly 350 fps ,1.14J with 0.2g bbs (EU field legal)

      Feels sturdy and shoots consistently. Never had any issues with it.

      (Remember to have the compressed coils in the rear.)

      Not much to say about this. Bought it so I would have a backup option in case I made my gun too powerful after messing with the gearbox following some upgrades.

      From my inspection, it feels sturdy enough and can't see anyone having issues with this brand.

      A good spring, good quality and works well. I got it paired with my UTR45 since it had a quick change spring mechanism. Handy thing to have if you want to play range in the morning and then maybe cqb in the afternoon.

      Overall a good product, would recommend it to just have as a spare in your toolbox or something incase you get the feeling that you want to go cqb.
