S+ Air-cushion inner barrel - 554mm
T-N.T. inner barrel series is common platform, has been pre-completed with the side cut groove of AEG, GBB, and VSR, suitable the almost HOP-UP bucking on the market.
●For major brands AEG, GBB. VSR
●Length can be customized.
(There may be a few brands of guns that have special specifications and need to be modified by the customer.)
1. Raise the BB standby initial position and place BB projectile in the center of the inner barrel (coaxial with the nozzle), make the T-HOP bucking's curved pressing block and BB form a more complete force area, so the HOP-UP effect more stable.
2. Because raise the BB standby initial position, the contact area with the inner barrel becomes smaller, effectively reduce the friction at the bottom of the BB when shooting, so that can reduce the amount of HOP required, relatively make the HOP effect more certain, effectively increase the friction above the BB projectile, and the range of available BB weight is wider.
3. Because the resistance at the bottom of the BB is reduced, when shooting BB , the jump curve after the HOP-UP effect in the inner barrel is more moderate, let the HOP-UP effect and the BB projectile are accelerated more stably in the inner barrel.
4. The required HOP-UP reduction is reduced → Reduced gas loss (increased effective exhaust) → Muzzle kinetic energy increased slightly.
5. When BB in standby initial position, it's easier to be pressed back to nozzle by HOP-UP bucking's friction block, make BB more closer to nozzle.
6. Locktime shortened (time from piston release to BB leaving inner barrel).
7. Reduced sensitivity to dust and reduce BB drop off the wax powder situation.
