Dimensions: 18mm x 35mm
Length: 1400mm
Strength: 0.35mm

Please note these springs are packed undersized to allow you to easily fit them to the barrel.
Due to the thickness of the plastic box and the mainspring being small, we will send the spring without the box to significantly lower the postage costs
