TNT TR-Hop Bucking / Rubber 60° for GBB models, pack of 2
Other interesting articles:
This bucking is specially designed for barrels with a long HopUp window. (e.g. TNT, SLONG)
Due to the long contact surface inside, even heavy BBs can be hopped with little pressure without any problems.
T-Hop or TR-Hop?
We offer our customers both HopUp systems from TNT.
The T-Hop Bucking offers a 6.2mm long contact surface which is very suitable for slightly lighter BBs (up to 0.36g).
If you would like to use heavier BBs (up to 0.50g) or play with a lot of energy, please use the TR Bucking.
With this, the contact area is a little wider than with the T-Hop.
TR-Hop is not suitable for light BBs, as it can quickly lead to over-hopping.
Features:
- Rounded contact surface
- More contact surface on the HopUp Bucking
- BB is centered better in the barrel
- More stable trajectory
- also suitable for heavy BBs
- Suitable for GBB weapons
- Hardness: 60 °
- The set includes two buckings with identical hardness
We recommend the combination with TNT S+ tuning barrels.
This bucking can also be used (without a nose) in the TNT Terminator SRS / HTI HopUp Unit.
Recommended accessories:
- TNT S+ Tuningbarrel AEG/GBB and VSR Models
