Description: Please note that I have not increased my prices as others have, but I will have to soon as the cost of materials has doubled in recent months, grab them while they are still cheap. By controlling the speed of your airgun's slug or pellet as it exits the barrel, users can obtain greater levels of accuracy, power output, shot count and consistency (depending on what the shooter wants regarding their airgun's performance).

Installation: Disassemble the airgun and remove the valveopen the valve and take note of the arrangement of internal parts within the valveReplace the check valve and reassemble Package contents: 1x Check Valve Frequently Asked Question 1: How do I know what "Preload" I need? Answer: The only way to know what size preload you need is to test the results before and after installation with the use of a chronograph. Some people want maximum power, some want a higher shot count, some want the best consistency.The lower the "preload" the less tension on the valve spring = more powerThe less "preload" the less space taken up inside the valve = more powerThese parts are made available in different sizes for those wanting to experiment or tune their airgunIf you just want a replacement part for what's already in your airgun, please take it apart and check the size before ordering. The old Crosman Medalist 1377 pistol we have here featured a 4mm mid section. Measurements for the preload are taken from the mid section of the component.
