This set includes both the Stainless Steel Piston and Aluminium Spring Guide. After consideration it didn’t make sense selling them separately so they are sold as a kit.
These are made right here in the UK!. Quality British Engineering!
The piston is heavier than the standard part which can aid with the use of heavier BB’s. It will also last forever. As long as we have them in stock. If you manage to break one we will always replace it free of charge but honestly you would need to be doing something very wrong to damage it at all. It will be the strongest part in the rifle.
