簡易辨別日蝕管的方法: 將BB彈放在內管入口處,從窗口處使用手指壓住BB彈,接著使用手電筒或是光源由出口處向內管照射。若呈現一個如同「日蝕」的狀態,那就是日蝕管。 How to identify S+inner barrel: The correct way to identify S+inner barrel is to place the BB at the entrance of the inner barrel, press the BB with your fingers from the window, and use a flashlight or light source to illuminate the inner barrel from the exit. If it presents a state like a "solar eclipse", it is S+inner barrel.
【Introduction of T-N.T. inner barrel Series】 The precision inner barrel series of T-N.T. are all designed as a universal platform, only need to replace different types of bucking according to the gun type, which can be installed on AEG, GBB or VSR sniper rifles. Most of the existing sizes are complete, and custom sizes can also be cut on your need
【Types of T-N.T. Inner barrel Series】 1.Standard type - Precision double inner diameter air-cushion inner barrel (outer diameter 8.5mm, inner diameter 6.03~6.35mm) It is the so-called "air-cushion barrel", a patented product of T-N.T. two different inner diameters were made in the same barrel, and the larger inner diameter at the outlet end was used to create a gas-coated BB to cause an "air-cushion effect". Because it is the same inner barrel, the coaxiality is better.
2.S+ Precision double inner diameter ECLIPSE air-cushion inner barrel (outer diameter 8.5mm, inner diameter 6.03~6.35mm) Based on the standard air-cushion barrel, a boss is designed at the bottom of the inner wall of the inlet end of the inner barrel, which can place the starting position of the BB before the launch in the middle of the inner barrel and try to be coaxial with the nozzle, and can reduce the distance between the BB and the nozzle. The contact area of the inner barrel, reducing the down pressure requirement for the HOP-UP (conversely, heavier BBs can be used), slowing down the beating amplitude of the BB after rushing through the friction point of the HOP-UP in the inner barrel, etc. . Simply put, it is an upgraded air-cushion barrel that improves ballistic stability.
3.H+ Precision double inner diameter Heavy Air-cushion inner barrel (outer diameter 9.95mm, inner diameter 6.03~6.35mm) Based on the standard air-cushion barrel, the thicker barrel diameter means better anti-resonance performance, which can effectively reduce the impact of the resonance of the inner barrel on the ballistics during firing, thereby improving the ballistic stability. The original design is for various types of hand-pulled sniper rifles, but as long as the inner diameter of the outer barrel is large enough, even AEG or GBB can be installed and used.
4.HS+ Precision double inner diameter ECLIPSE air-cushion heavy barrel (outer diameter 9.95mm, inner diameter 6.03~6.35mm) Based on H+ air-cushion barrel, combined with the characteristics of S+ barrel, it has the highest-grade inner barrel type that combines the performance of the above two inner barrels.
【How to choose a precision inner barrel?】 There are many refit brands on the market, each of which has its own characteristic performance, so how to choose the inner barrel? As we all know, the inner barrel is a channel for the BB to travel, and it is also one of the core components of the soul of every airsoft BB gun. For a good precision barrel product, the most intuitive is the straightness of the inner barrel and the smoothness of the inner wall, which are the most basic and most important.
●The flatness of the inner wall? It is suggested that you can pick up the precision barrel in your hand and face it against a brighter light-colored background, and use the refraction of light and shadow to observe whether there are subtle "wave patterns" in the barrel with the naked eye. The more wavy lines, the more uneven the inner wall, which means that the car is running on an uneven road. And all kinds of ditching, grooving, opening, etc., just like potholes on asphalt roads after heavy rain, may also cause varying degrees of impact. ●The true straightness of the inner barrel? Some people will judge straightness by rolling the inner barrel, which is sometimes not very accurate. It is suggested that you can pick up the precision barrel in your hand and face it against a brighter light-colored background. Using the refraction of light and shadow, you will see several "halo" in the barrel with the naked eye. If these halo appear as "concentric circles" , the higher the true straightness of the inner barrel. (Of course, in very rare cases, it may happen that the inner diameter is straight but the outer diameter is crooked, which may be a defective product with some problems in processing...) ● Coaxiality of the inner barrel? The better the coaxiality, the straighter the channel for the BB to travel. In any case where the inner barrel are connected to each other, 100% coaxiality may not be guaranteed, and it may also cause varying degrees of influence.
※Air cushion length:40-50MM ※Shorter barrel have no Air-cushion design (Shorter than 220mm) ※短內管無氣墊槽設計※ ※Shorter barrel have no Air-cushion design (Shorter than 220mm)※
因為內管太短氣墊效應不明顯,所以220mm以下的精密管無氣墊槽設計。 Because the inner barrel is too short and the air cushion effect is not obvious, inner barrels below 220mm have no air cushion groove design.
※精密管材質:青銅,表面電鍍化學鎳。 ※Inner barrel material: bronze&electroplated chemical nickel.
