This nice AEG bucking is a great fit for most AEG's. It'll lift heavy BB's, but it's not a crazy wide or long patch design that only works with heavy bb's.
The square backspin patch is also made with nice edge support, and won't flay over time as seen on some other brands. Innerbarrels can have different size cuts on the barrelwindow; some are narrower than others. For the 4UAD Friction Pro bucking, this is not an issue. The medium sized backspin patch gives a good grip while staying around from tilting on any edges. With good performance and good parts compatibility, this bucking is easy to recommend for a broad range of airsoft AEG's.
AEG weight range Within normal 1-1.5Joule AEG's, this bucking is optimal for .32G BB, with a function rating from 0.25 to 0.40g BB.

Installation guidance Install like any other AEG bucking; put bucking onto the barrel and gently guide it into position in the chamber. There should be some resistance, but the bucking must not stretch. Install the C-clip and push a BB through the front lips; there should be no or only a light force required to move the BB. Use the included concave nub for optimal performance, or use a normal roll nub with lower weight BB's (0.20-0.28g BB's).
