2G Hop Up Bucking
by KWA
This is an upgraded replacement rubber bucking for your hop-up. These are the same OEM buckings used in KWA's line of 2009 and up AEGs. Part#159-2G
The 2G bucking features "fingers" that apply more equal pressure to the BB and provide more control over the hop as opposed to the standard "hump" produced by most other bucking/nub combos.
KWA designed the 2G bucking to improve overall performance of the KWA 2G hop-up unit. When installed properly, it will enhance accuracy, distance, and consistency.
Does not include nub. Sold separately.
We DO NOT recommend using the 2G bucking with concave or H-style nubs.
