P RODUCT FEATURES
(1) Imported high-quality springs are more fatigue-resistant, aluminum alloy spring
seat snap ring assembly
(2) Adopt CNC machining center and other machine tools to refine the movement,
and the rebound value is guaranteed.
(3) Silicone bracket for soft hand protection, more comfortable rebound operation.
(4) Finely grind the spherical zero-setting screws to make the rebound firing smoother
and smoother.
(5) Improved pointer design, easy to adjust friction and more stable.
(6) Beautiful label and ruler are easy to read, and the hard oxidation treatment of the
parts is beautiful and durable.
(7) High-precision aluminum alloy flange is not easy to be damaged, and
high-precision hook is not easy to be elastically empty due to abrasion.
(8) Multiple original imported dust-proof components, cleaner movement and longermaintenance period
(9) Abrasion resistance of super-hard 6061 aluminum alloy casing, and the button is not easy to fall off by stretching process.
