CLASSIC ARMY – M24 Tuning Kit


This Tuningkit for the old Classic Army M24 (not compatible with M24 LTR) is manufactured by the same tech-team who also makes the Tuningkit for my VSR-10 sniper rifle.

I installed the VSR-10 Tuningkit into my airsoft sniper 8 years ago and it shot about 60.000 BBs through the barrel. It has never failed or disappointed me so far. All Novritsch Tuningkits are made to the same technical requirements, so they all provide the same power and accuracy.

The parts are handcrafted, tested and shipped from South East Asia to every country around the world in 2 weeks. The tech team knows what they are doing, putting in a lot of research and effort into the Novritsch Tuningkits to provide the best quality spring sniper upgrade kits available on the airsoft market.

The Tuningkit includes everything required to achieve the same power and accuracy you see from my videos.

6.01 Precision Barrel, Barrel spacer, Cylinder, Cylinder Head, 7mm Spring Guide, High Pressure Piston, 90° Piston Sear, Spring Guide Stopper, Spring Guide Stopper Screw + Nut

Gun is not included in the Tuningkit!

If you want a gun that shoots as powerful and accurate as mine, just get a Classic Army M24 Civilian or Military version and install this Kit into your rifle.

If you are not experienced with working on airsoft sniper rifles this product is not for you.

Upgrading an airsoft sniper rifle can be difficult. If you have never done it before, I recommend getting a Novritsch SSG24 instead since it’s a out of the box solution which shoots as good as a gun upgraded with a Tuningkit – no modificatons needed.

By purchasing one of these Tuning Kits you are not just upgrading your gun to the highest possible performance level in airsoft. You are also supporting me, so I can continue to create videos on my youtube channel.

Spring selection

The only thing you have to select is the spring power. Everything else is already included in the kit.



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. 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. Also there are 3 bolt handle stopper pins in the back of the Cylinder to prevent the bolthandle from getting damaged.

Cylinder head

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.

Barrel Spacer

The Derlin Barrel spacer keeps the Precisionbarrel centered in the outer barrel.
Two orings on the outside and one oring on the inside secure the barrel in place.

Spring Guide Stopper

The Spring Guide Stopper is of tempered 4403 tool steel and redesigned for better durability. A reeinforced screw is included which supports the spring guide stopper. With this parts installed the trigger can handle spring which are even stonger than the 650 fps spring.

Piston sear

The 90° piston sear is milled out of one solid piece of tempered 4403 tool steel. It is redesigned to handle even greater forces.
