S+ Air-cushion Inner barrel 6,03 mm - 554mm

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.
