Description

High quality upgrade set from T-N.T., which simply replaces the original barrel with chamber without the need for further modifications.

The barrel is made of one piece of bronze and then electroplated with nickel. This makes its surface very hard and smooth, which is the basis for barrel durability and shooting accuracy.

The window for the bucking is much larger than in conventional barrels. It is thus possible to use a bucking with a large pressure area (up to 7 mm), thanks to which it is possible to use heavier BBs and obtain even better accuracy and stability of the BB. The barrel is compatible with both AEG and GBB type bucking. T-N.T.

The package also includes a H.L.R. Hop (Hyper Long Range) 60° bucking that was developed on the basis of T-HOP and TR-HOP. The BBs has a better positioning function and more accurate, which is more helpful to improve the stability of the ballistic and is designed for long range shooting. Even under the setting of low initial velocity, using with proper BBs, it can still have a very good shooting range.

CNC Hop-up chamber

The aluminium CNC chamber is made in one piece and thus has high strength and durability. There are screws in the front on the sides to secure the barrel so it won't wiggle and will stay firmly in the chamber. The pressure adjustment is very precise with a CNC adjustment wheel. The wide nub pushes perpendicular to the bucking, ensuring better pressure across the entire surface of the Hop-Up bucking.

Solar Eclipse (S+) barrel

In a conventional barrel, the BB is pushed to the underside of the barrel when passing through the hop-up bucking pressure. This increases friction and reduces the hop-up effect.

At the beginning of the S+ barrel, in the area of hop-up bucking, there is a micro hump on the underside of the barrel (height 0.04 mm) that lifts/centers the BB in the barrel and reduces its friction against the barrel in the initial phase of the shot. This allows you to use the hop-up more efficiently and get greater rotation with minimal energy loss.

Air-Cushion Effect

It is made possible by the double inner diameter of the barrel - 6,03 mm at the beginning and 6,35 mm with grooves (air channels) at the end. Thanks to them, the air flow behind the BB is directed and unwanted turbulence is reduced to a minimum.

Precision barrels (so called tight bore) have the advantage that there is less space around the BB and therefore there is not as much air leakage and reduction in performance as with standard barrels. Barrels with a large internal diameter (so-called wide bore) have a positive effect on the accuracy of the BB, because it does not bounce against the barrel walls to such an extent and is therefore more stable, but due to this "leakage" of air that they slightly reduce performance.

This range of barrels from T-N.T. combines the advantages of both. The barrel has a narrow 6.03 mm diameter for most of its length to achieve good tightness and performance, and a 6.35 mm diameter at the end when the BB has maximum energy and velocity for better stabilization.

is a taiwan based company established in 2004. In the beginning T-N.T. focused on custom modification of clients spring sniper rifles, AEGs, GBBs etc. After gaining many experience and answering to the need of the market, T-N.T. gradually transformed into the field of developing, designing, manufacturing upgrade parts for the most branded airsoft BB guns – such as unique Hop-Up bucking, inner barrels and CNC upgrade kits. All T-N.T. Studio's products are cutting edge, patented products designed with extreme precision.
