Airsoft Hop Up Bucking & Hop Up Chamber

Full Line of Airsoft Hop Up Buckings, Hop Up Chambers, and Hop Up related parts and upgrades. Hop Up Buckings are where the BB's rest before being fired. Hop Up buckings commonly rip and need to be replaced especially during BB jams. This is easy process of removing hop up chamber, pulling out barrel and slipping over barrel. Some Hop Up Buckings and Hop Up Chambers also claim higher and more consistent spin for tigher grouping. Hop Up Chambers can sometimes can crack, especially plastic ones, which then can be replaced with metal hop up chambers. Different Hop Up Chambers also claim to have differnt properties to apply Hop Up in an effective manner.
