▍Important information before purchase
The muzzle end of this product has a shape similar to an extension barrel, but this is for securing the cap; it does not provide a large-bore extension function.

▍Product development
Developed and manufactured in Japan

▍About TN barrels
KM's flagship product, the TN barrel, is made from carefully selected brass and finished with our proprietary TN coating. Our unique manufacturing process uses electroplating to control the coating thickness inside the barrel, achieving exceptionally high dimensional accuracy based on a 6.04 mm inner diameter.

▍History of TN barrels
Since its launch in 1989, the TN barrel has remained a long-selling series. Its high quality and dimensional accuracy, ensured by fully integrated domestic production, have earned it the support of many airsoft users.

▍HOP groove machining
HOP grooves require extremely precise machining.
Most standard HOP grooves are machined using an end mill on a lathe or similar equipment.
Although our process takes more time and costs more,
we machine each HOP groove individually using a submersible EDM machine.
*Some products, such as those with HOP grooves in the form of holes, are machined using an end mill.

▍TN coating
TN coating is a special Teflon coating made with a Teflon base blended with several types of additives. It provides excellent friction resistance and smoothness, and is more durable than conventional electroplated coatings.

It also resists dirt buildup and is easy to maintain. Its performance can be readily preserved with regular cleaning alone.

▍Firing performance
TN coating's excellent smoothness and the high-precision 6.04 mm inner diameter help reduce resistance as BBs pass through, delivering a stable muzzle velocity and excellent shot grouping.

In addition, precise control of the inner diameter and a uniform interior finish reduce lateral BB movement and improve trajectory straightness. As a standard TN barrel—not a large-bore model—with a 6.04 mm inner diameter throughout its 229 mm length, it delivers high accuracy and consistent shooting performance.
