Airsoft Masterpiece Valve Knocker Springs
Lost your valve knocker spring or just purchased steel internal parts?
These are perfect replacements to ensure your capa is running at it's best.
The stock TM knocker spring tends to wear out due to slide cycling, this can lead to abnormal FPS and poor gas efficiency - pop one of these in and you're good to go!
*if you require any help with fitting these parts please get in touch - whether that be guidance or if you require them to be actually fitted.
