Product Description
This TN inner barrel with an integrated large-bore rectifier is compatible with Tokyo Marui next-generation electric guns: H&K MP5A4 / MP5A5 / MP5SD6 and EVOLT M4A1 Carbine / FPR-Mk4.

The front section is a high-precision TN barrel with a 6.04 mm inner diameter, integrated with a 60 mm-long, 7.5 mm inner-diameter large-bore extension at the muzzle end. This high-performance model combines the accuracy of a TN barrel with the airflow-straightening effect of the large bore.

▍About TN Barrels

KM's flagship product, the TN barrel, is made from carefully selected brass and treated with our proprietary TN coating. Using our unique process, the coating thickness is electro-deposition-adjusted inside the hollow barrel, producing a barrel with a standard 6.04 mm inner diameter and extremely tight dimensional tolerances.


▍History of TN Barrels

Since its launch in 1989, the TN barrel has remained a long-selling series. Its high quality and dimensional precision, achieved through fully integrated domestic production, have made it a favorite among airsoft users for many years.


▍Hop Groove Machining

Hop grooves require extremely precise machining.
Most standard hop grooves are machined using an end mill on a lathe or similar machine.
Although our process takes more time and costs more,
we machine each hop groove individually using a plunge-type electrical discharge machining system.
*Some products with holes or other features in the hop groove are machined using an end mill.


▍TN Coating

TN coating is a specialized Teflon coating made by combining a Teflon base with several types of additives.
It offers excellent abrasion resistance and smoothness, and is more durable than conventional electroplating.
TN coating resists dirt and is easy to maintain, so it does not require especially meticulous care. Periodically clean the inner barrel with a maintenance rod to keep it performing well.


▍Large-Bore Rectifier System

A 60 mm-long, 7.5 mm inner-diameter large-bore extension is integrated at the muzzle end.
After gaining ample spin and acceleration in the high-precision TN barrel with its 6.04 mm inner diameter, the BB passes into the 7.5 mm large-bore section without making contact with it.
By smoothing the flow of compressed air that follows the BB through the large-bore section, the system suppresses turbulence as air exits the muzzle. This structure is designed to reduce unwanted lateral forces on the BB and improve trajectory stability through its rectifying effect.

▍Firing Performance

The TN coating's smooth surface and the balanced 6.04 mm inner diameter reduce resistance and ensure stable firing. The 6.04 mm design offers an excellent balance of muzzle velocity, shot grouping, and reliable operation, making it easy to use.
In addition, the 60 mm large-bore rectifier section at the muzzle end smooths airflow immediately before the BB is fired. Along with the TN barrel's inherent accuracy and straight trajectory, achieved through precise control of the inner diameter and a uniform interior finish, this model is designed to improve trajectory stability at medium to long range.
