DYTAC MWS Complete Hop Up Chamber Adjuster Set CNC Aluminum w/ 65 Degree FKM Hop Up Bucking for Marui TM MWS GBB

FKM material (Hop Up Bucking) is a type of rubber used in airsoft guns for the hop-up system. It is made from FKM (Fluoroelastomer) material, which offers excellent sealing performance, durability, and chemical resistance.

The hop-up system is an essential component in airsoft guns that allows for better accuracy and range. The FKM material used in the hop-up bucking provides a good airtight seal between the BB and the barrel, ensuring that the BB travels straight and true to the target. It also reduces friction between the BB and barrel, allowing for improved accuracy and consistency.

In addition, FKM material (Hop Up Bucking) offers excellent resistance to silicone oil, which is commonly used in gas-powered airsoft guns. This resistance to silicone oil helps to prevent the hop-up bucking from swelling or deteriorating over time, ensuring that it maintains its performance and durability.

FKM material (Hop Up Bucking) is known for its excellent durability and chemical stability. The FKM material is also resistant to ozone, weathering, and aging, which helps to extend the lifespan of the hop-up bucking.
