LOL HW97 broken spring!!!

Kinda shocked you didnt hear or feel that let go. Im guessing the lower power from the break was causing the accuracy improvement?

I'd put this in it. They work very well used his stuff for years.

I’ve never heard any crack or odd sound when a spring breaks. The give away that sometimes is amiss is loss of power or odd noises when the gun is cocked.

I have the ARH kit in my hw97k and have been very pleased with how it shoots. Mine is at about 12.5fpe.

When the spring broke in my R7, accuracy left the building. Suddenly I noticed "clicking" sounds when I cocked it. Then the light came on. After AZ "stroked" it a bit, it was driving tacks again.

How often do they break? Can I do anything to avoid?

Broken springs are pretty rare. I’ve put between 80,000-100,000 shots through my hw97k, pro sport and R7s and have only had two broken springs. Once in an R7 with a Vortek kit that boosted power to about 7.5fpe and once in the pro sport with another Vortek SHO kit. But each of those kits gave me more than 15,000 shots so I can’t really complain. After putting 12fpe kits (ARH in the hw97k and Vortek in the pro sport) into my hw97k and pro sport I have yet to see a broken spring after 20,000+ shots. On an absolute basis, spring longevity is excellent and springs are cheap (i.e., $15-20) and easy to replace when necessary.

Best way to avoid a broken spring is to never dry fire the gun (i.e., shoot it without a pellet in breech). Keeping the power down probably helps a bit too, although if you want more power you’re still likely to get 10,000 shots or more.

Or another alternative to ARH is a Vortek kit.

The Vortek kit has a sleeve that keeps the spring on the straight and narrow along with a small thimble of tar and a piston seal.

The spring guide fits tight and the entire package just about kills all vibration and spring twang.
