We have well over 10 years of tuning and customising experience of these guns, so can offer a wealth of advice to anyone who thinks they may need a little help with their new project. And remember, we are here to help, and the advice is always free!



We offer Custom Parts and Genuine Spares.

We offer a range of quality custom and standard parts that are made to enhance the look, feel, and function of your Crosman. Most of our custom parts are made from either anodised aluminium or stainless steel, to give your Crosman a modern and cutting edge look.


We also stock a range of genuine spares for these guns, so if you have lost or broken something, get in touch, we may just have it!







These guns are very popular and have great appeal because they are relatively inexpensive, basic, and easy to work on. And best of all, you’ll have just as much fun tinkering and customising them as you will shooting them. And generally whatever you change, or modify, ends up improving the gun. Many of the parts are common amongst the models too, so you can come up with a range of designs by simply interchanging the various parts.


The key to getting the most from the CO2 powered guns is understanding how CO2 actually works. There is a wealth of  information available on the internet, and you can check out our links page to get you started. So buy yourself a new Crosman, start customising, and have some fun!

As with any changes, disassembly and reassembly, modifications and/or alterations of an air gun or any of its parts, there is always the possibility of compromising the operation and safety of the air gun. It is important to make sure all parts have been fitted correctly and that the safe working of the gun has not been compromised in any way.

By accepting and using these custom parts, you and you alone accept any and all responsibility in the operation and safety of the gun or guns that these parts are being installed, and will hold no other person or persons responsible.
