1. Stainless steel screw-up outer diameter 10mm, length 60mm, tube depth 13mm, can be concealed in standard 11mm and non-standard concave-convex tubes, and can also be concealed in all flames on the market without reaming. No spin-up design, most sights are easy to return to zero.
2. There are four sets of upspins. The four upspins have different friction textures and angles, and can adapt to launchers with different initial speeds, air volumes, and diameters.
The upper spin is still in the beta test modification stage, and I have not counted what kind of initial velocity, spring diameter, and gas volume the four upper spins are suitable for.
Therefore, we do not accept inquiries about which number of four spins can be adapted to your launcher, or which initial velocity, spring diameter, and volume of each spin are suitable for.
It is suggested that friends who want to purchase only one label of the upper spin can perfectly fit their own launcher. They can borrow a friend's trial and then directly purchase a specific label of the upper spin.
3. Turn the inner part of the tail through 9.6. The inner tube that is suitable for you can use the pipe cutter to gently press out two dents at the tail, and then insert the inner tube to adjust it slowly according to the tightness to achieve glue-free and harmless installation.
4. Public test products, and because of a set of four spin-ups, customers may purchase a label with a spin-up and return it repeatedly to find a spin-up suitable for their transmitter label, so this batch of beta products does not accept return for any reason, such as Do not buy if in doubt.
5. Friends participating in this public test, please kindly share the data of your launcher with the up-spin of the selected applicable label for other players' reference.
