High-performance hammer weights & pre-loaded spring guides
Improve power, consistency, and tuning control — with a simple drop-in upgrade.
Take your airgun to the next level with our precision CNC-machined hammer guides. Designed and manufactured in the UK, these components let you fine-tune your hammer system for smoother operation, tighter groups, and improved shot stability — whether you shoot pellets or slugs.
Stronger, smoother hammer strike for more consistent velocities
Improved shot-to-shot consistency (tighter groups at all ranges)
Better tuning control for slugs and heavier ammo
Faster lock time for reduced shooter error
No permanent modifications — quick, simple drop-in installation
CNC-machined in the UK from strong, corrosion-resistant materials
These guides can be installed in two ways, depending on the result you want:
For shooters who want more momentum behind the hammer.
Adds mass for a stronger, smoother hammer strike
Holds the valve open slightly longer for increased airflow
Helps maintain consistent power with heavier ammo
Best for: slug shooters, hunting, or anyone wanting more punch.
For shooters who want crisp, repeatable performance.
Adds tension for faster lock time
Improves shot-to-shot consistency
Helps tune your gun to a specific pellet or slug
Best for: precision shooting, competition, or maximising consistency.
Drop-in fit — no cutting, drilling, or permanent changes
Takes only a few minutes
Works with all airgun calibres (.177–.30)
Compatible with standard hammer springs
Simply install at the front (weight) or rear (pre-load) depending on your tuning goals.
We’ve kept prices as low as possible, but with material and tooling costs continuing to rise, we will eventually need to increase prices on future batches. So it’s worth grabbing one now while they’re still at the lower price.

There’s no universal “best” guide — every airgun is slightly different.
Most shooters pick 2–3 sizes to find the perfect setup for their pellet/slug and tune.
For best results, measure your velocity before and after using a chronograph.
We also design and CNC-machine bespoke airgun components.
If you need a specific size, weight, or new idea — we can build it.
