HOP-UP Bucking Shims – Airsoftparts are designed for precise adjustment of the HOP-UP bucking position inside the chamber, helping to solve issues caused by dimensional differences between buckings from various manufacturers. A bucking neck that is too short can cause air leaks between the nozzle and bucking, while one that is too long may negatively affect BB feeding. With a thickness of 0.2 mm, these shims allow precise positioning of the bucking for maximum sealing and reliable system performance. Made from stainless steel without surface treatment, they feature an outer diameter of 9.85 mm, making them compatible with most standard HOP-UP chambers.
