We have received many questions from players asking: Why is T-N.T.'s rubber not interchangeable?
Each model has a different hop-up nozzle length. To achieve the best BB feeding position and ensure the BB is accurately positioned under the contact point, we aim for a more stable and extended trajectory.
Standardizing the rubber would make our production process simpler and easier. However, the hop-up chamber we developed is an upgrade kit designed to enhance stock performance, enabling your model to achieve better performance. The "BB feeding position" is a critical factor in this. Therefore, the length of each rubber is custom-made based on the hop-up nozzle length of each model.
Additionally, we offer various types of rubbers for different BB weights. Please pay attention when choosing rubber, indicate the gun type to achieve optimal performance. If you have any questions, please contact our distributors or private message us.
Many players have questions, why is there no universal design for T-N.T. HOP-UP bucking?
Each nozzle are not the same length. In order to make the T-N.T. upgrade kit have the best performance, make the BB accurately into the correct HOP-UP pressure point position, and pursue a more stable extended trajectory. After precise calculation and design, we develop located directional rubber corresponding to various brands GBB.
Therefore, T-N.T. HOP-UP chamber needs to be matched with our specified rubber. Each rubber is slightly different in size and design. Please pay attention when choosing rubber, indicate the gun type to achieve optimal performance. If you have any questions, please contact our distributors or private message us.
T-HOP Bucking ●Standard universal type, suitable for GBBP, SMG and Rifles etc. Most our kits are included this type. ●The initial velocity configuration is low to medium, and it is recommended to use 0.25g ~ 0.4g up bbs. ●It can almost correspond to most of the stock HOP nub or narrow type HOP arm.
TR-HOP Bucking ●Specialized sniper type, suitable for sniper rifles, with a wider HOP-UP contact surface. Most our sniper kits are included this type. ●The muzzle velocity configuration is medium to high, and it is recommended to use 0.36g or more. ●It is recommended to use with a wider HOP nub or HOP arm.
H.L.R. Bucking ● Combined with the first two and improved, GBBP, Rifles, SMG, Sniper rifles can be used, but still need to consider the initial velocity setting and the configuration of the used ammunition. (The kits of some gun models do not support H.L.R. bucking due to the design of the HOP nub) ●It is recommended to use 0.4g or more heavier bbs. ●It is recommended to use with wider HOP nub or HOP arm.
FLAT-HOP Bucking ●The AEG bucking specification, has no internal pressure zone design. ● It can be used freely with various styles of HOP nub on the market. (Please first confirm whether the HOP window size of the inner tube is suitable for the pressing block)
TL-HOP Bucking ●It is recommended to use 0.12g~0.32g bbs. ●Based on H.L.R. rubber,followed the design of the arcuate pressure zone "from front to back, from left to right", which eases the angle of stress and release. It is suitable for low muzzle velocity pistols or competition short guns. ※The above are all basic principles of use. Players can still change various configurations and fine-tuning according to your usage habits. ※
【Which degrees of HOP-UP bucking should I choose? 】
Rubber material: ●50 degrees: generally recommended for low temperature and cold areas. ●️60 degrees: Under normal conditions, it is recommended to use 60 degrees.
Silicone material: ●60 degrees: Under normal conditions, it is recommended to use 60 degrees. ●️70 degrees: 70 degrees can be selected for high initial speed setting. ※The above are all basic principles of use. Players can still change various configurations and fine-tuning according to their usage habits. ※
【Which material of HOP-UP bucking should I choose? 】
Rubber material: ●Range performance and ballistic stability are good, more wear-resistant, longer service life. ●It is more easily affected by temperature, which is the we called "cold gun effect".
Silicone material: ●The friction force is large and the range is very long, but the ballistic stability is slightly worse than that of the rubber material. ●It is less sensitive to temperature and less prone to the so-called "cold gun effect".
