Product Summary

Our Hammer Weights and Spring Guides are the perfect upgrade for any shooter looking to improve their shot-to-shot consistency and accuracy. Designed and CNC made in the UK, this high-quality accessory is made from brass, selected for its weight and corrosion resistance.


Approximate Weights (in grams)

  • 1mm Preload 4.20
  • 2mm Preload 4.40
  • 3mm Preload 4.64
  • 4mm Preload 4.83
  • 5mm Preload 4.98



This item is to be installed either at the front or rear of the hammer spring. Depending on which configuration you choose, will alter the type of performance you can expect.

  • Hammer weights "add weight" to the front of the hammer spring. This additional weight will effect the amount of time the valve stays open (these guides are made in brass for the extra weight the material provides).
  • Preloaded spring guides that are installed at the rear of the spring "add additional tension" to the hammer spring itself. By installing the guide this way, users can expect a faster lock time (time between pulling the trigger and the pellet leaving the muzzle) as well as an increase in power output. The higher the preload, the more tension on the hammer spring = more power.
  • This item is to replace the original "removable" plastic guide that comes fitted as standard

It's important to note that the higher the preload, the more tension on the hammer spring and therefore, the more power you'll get. Be sure to check your results with a chronograph to ensure you're within your country's power limits.
