As the saying goes : "A good start is half the success".
TAIWAN T-N.T. STUDIO has been pursuing a breakthrough in performance, and the pace of research and development has never stopped.
We have developed T-HOP series bucking, double I/D inner precision air-cushion inner barrel series, etc. Effectively increase the stabilizing friction required for BB, also created more far-reaching effective flight distance.
Now, introduce you T-N.T. new patented design of inner barrel :
【Solar Eclipse inner barrel】!!
(We refer to this product as【S+ barrel】)
The【Solar Eclipse barrel】has the following features, below we will make simple explanation with photos, please refer the article :
【BB & Inner barrel - Schematic】Normal vs. S+ barrel
(inner barrel I/D 6.03mm , BBs O/D 5.95mm)
●GREEN area - inside of HOP bucking / pressure area.
●BLUE area - S+ positioning area / 0.04mm
(the photo is that we use light and shadow and adjust the photo slightly to facilitate the seeing.)
●RED area - BB contact with the inner barrel's area.
↓↓↓ Normal barrel ↓↓↓ ↓↓↓ S+ barrel ↓↓↓
 
【Normal barrel】because the BB's outer diameter must smaller than barrel's inner diameter, so the BB is slightly below the standby position (as shown), and because of the close curvature of the two, so the contact area (RED area) is wider and the friction is larger.
 
【S+ barrel】keeps the BB in center at the standby position (as shown) and remains coaxial with the nozzle, effectively reducing the friction between the lower edge of the BB and the barrel inner wall. (BLUE area).
 
【Sectional view of the inner barrel】
1. Raise the BB standby initial position (BLUE area) and place BB projectile in the center of the inner barrel (coaxial with the nozzle), make the T-HOP bucking's curved pressing block (GREEN area) and BB form a more complete force area, so the HOP-UP effect more stable.
(The blue area in the photo is to explain the principle and does not represent the actual situation.)
There is a "micro hump" design with a rib directly below the entrance of the inner barrel. The BB is more stable on the support zone surface, and the inner barrel is integrally formed.
(The micro hump is just 0.04mm, all photos is that we use light and shadow and adjust the photo slightly to facilitate the seeing, the micro hump is really hard to see it by eyes, suggest you can put a BB into the barrel entry, then use finger to simulate HOP, then you can see it.)
 
2. Because raise the BB standby initial position (BLUE area), the contact area with the inner barrel becomes smaller, effectively reduce the friction at the bottom of the BB when shooting (RED area), so that can reduce the amount of HOP required and relatively make the HOP effect more certain (GREEN area), effectively increase the friction above the BB projectile, and the range of available BB weight is wider.
(The micro hump is just 0.04mm, all photos is that we use light and shadow and adjust the photo slightly to facilitate the seeing, the micro hump is really hard to see it by eyes, suggest you can put a BB into the barrel entry, then use finger to simulate HOP, then you can see it.)
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.
8. The S+ barrel is ONE PIECE designed , more higher precision!!

●All products are recommended to have DIY ability to make fine adjustments and modifications.
●Before the modify, recommended to check and exclude the original issues to achieve the best results, or commissioned by the store to modified.
●Replacement of kits does not mean that can solve all the original parts of the issues, sometimes still have to modify the other components to achieve the best performance.
