Got a Kingman Spyder paintball gun with metric-threaded inputs? Need a new in line regulator, bottom-line hose, drop forward, gas-thru foregrip or expansion chamber? Be prepared! If you want to add aftermarket modifications, you'll most likely need this standard to metric adapter for your hosing. This allows you to use standard 1/8" NPT threaded hoses and fittings on your metric threaded paintball gun. Convert almost any metric marker's air line system to accept standard aftermarket modifications. Adapter has 1/8 NPT female fitting and M10 x 1.25 male metric fitting.
