This nice TM bucking is a great fit for most GBB's, GBBR's and VSR's.
It's easy to install and made of a solid material that will last a long time.
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 GBB 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 replicas.
GBB weight range As always, you get the best precision and range with a heavy BB. I recommend to use 0.28g BB or heavier with this bucking. The manufacturer rates it for up to 0.48 in GBB use, depending on your chamber.
In a stock TM Hi-Capa 5.1, this bucking lifts up to a 0.32. So it's a great simple upgrade for a budget gun. With additional hopup arm upgrades, heavier BB weights are possible.
For the TM MWS, this bucking can easily lift up to 0.48 without any other modifications or hopup arm changes.

Installation guidance Install like any other GBB bucking. Make sure it sits nice and straight and no section is pinched or overly squeezed when chamber is re-assembled. Depending on your particular hop-up chamber, you can use the included nub or not.
