Unlock the hidden performance potential of your pre-charged pneumatic airgun. These high-flow transfer ports are engineered to help shooters optimise for greater consistency, improved accuracy, and more efficient power delivery — depending on how you choose to tune your airgun.
Precision CNC-machined from high-grade, corrosion-resistant materials, each port is built to tight tolerances for repeatable results. Easy to install, and designed as a direct replacement for the factory port — no permanent modifications are required.
Note: Many factors influence performance — calibre, barrel length, ammo choice, and spring condition, among others. There is no universal “correct” port size or setup for every airgun, this is why we recommend you test a selection of ports in various sizes, measuring results with the use of a chronograph, before and after installation.

For direct replacement or experimental tuning (with pellets or slugs across various power levels)
Improve velocity and consistency for tighter groupings
Increase power potential
Maximise efficiency for better shot count
Simple, cost-effective upgrade for noticeable performance gains
Ideal for tuners, hunters, and precision shooters — looking for the utmost performance from their airgun
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.
We strongly recommend using a chronograph to measure muzzle velocity / muzzle energy before and after installing or tuning with these transfer ports. Small changes in airflow can noticeably alter output — always ensure you remain within your local legal power limits.
Need something custom?
We also design and CNC-machine bespoke airgun components.
If you need a specific size, flow profile, or new idea — we can build it.
