High Pressure Piston
The polyurethane seal cap is an industrial standard for high pressure systems. It provides better seal than standard O-rings and is oil and acid resistant. The Piston also comes with a teflon glide ring for extra smooth piston travel.
To keep the Piston leightweight the shaft is made from anodized alloy. The base, where all the force of the sears is applied, is out of stainless steel. This material combination makes the piston durable but still lightweight.
The springs are made from Silicon Chrome Steel. This material allows light compression but fast return.
The springs also get compressed for a week before they get shipped, to provide the best fps consistency possible.
I prefer the Strong Spring (550 fps 0,2g BBs) but you can choose your desired fps in the spring selection.
The Springguide is highly polished to reduce the friction between the Springguide and the spring. It has an extended length for maximum guide. The base perfectly fits into the High Pressure Piston, this prevents the system from slamfiring.
Unlike other brands springguides this one is made from one solid piece of stainless steel.
The Cylinder’s outer surface is highly polished to reduce friction while compressing the spring. The inner surface is polished to a mirror finish which supports the seal of the High Pressure Piston. It also reduces the friction of the Piston travel.
The back of the Cylinder is threaded into the stainless steel shaft and secured with 3 pins. This makes the Cylinder extremely durable.
The double O-rings provide a perfect seal, even at the high air pressure produced by the 650 fps spring.
The lengh of the polished stainless steel nozzle is optimized for constant BB backspin.
6.01 Precision Barrel
This barrel is the most unique part of the Tuningkit. It gets polished by hand for several hours to achieve this kind of perfection. A real mirror finish reduces the friction between BB and barrel to a level that the velocity of the airsoft BB gets boosted up to 20 fps. (The gained fps are already included in the spring selection)
Unlike any other precision barrel on the Airsoft market, it gets straightened in a complex process and checked with a sensitive measurement device to ensure that the barrel is perfectly straight.The material used is a durable and oxidation resistant High Speed Brass.
The outer diameter is extended to 9,6mm to reduce the vibrations created by the release of the Piston.
The barrel has an excact inner diameter of 6.01 mm and at the last few centimeters it widens up to 6.02 to improve the accuracy performance of this barrel even more.
The Hopup window is optimized for R-Hop installation and standard hopup design.
This 6.01 precision barrel brings accuracy in Airsoft to a whole new level and is the major reason for the laser shots you’ve seen in my videos.
The Leakstopper Ring will boost up your rifle to +20 fps.
With this thin stainless steel ring installed you will have a perfect seal between the hopup bucking and the Precision Barrel.
The gained 20 fps are already added to the fps in the spring selection.
Spring Guide Stopper
The Spring Guide Stopper has an extended length to prevent the Spring Guide from jamming.
It’s made of tempered 4403 tool steel. With it’s extreme hardness, it can easily handle springs up to 800 fps.
The 90° sear is milled out of one solid piece of tempered 4403 tool steel. Due to it’s extreme hardness it will not wear down, no matter which spring you will install into your gun.
