Double Bell Kar98k Ejection Cartridge 30 pcs

Double Bell Kar98k Ejection Type Live Cartridge 3D Printed Item

Concept
I want to use live cartridge airsoft guns in airsoft games.
I don't want to use a cartridge catcher because it ruins the atmosphere.
The genuine aluminum cartridges also wear down the rim with use, causing ejection failures.
The trajectory varies depending on the quality of the O-ring used for retention.
Losing them is painful because they cost 600 yen each.

To solve these problems, I made this using a 3D printer and PLA.

- This model uses an ejection system. When you push the cartridge into the chamber with the bolt, the BB is ejected from the cartridge by the nozzle, resulting in less variation in trajectory and muzzle velocity due to the O-ring's grip.
- Since it does not use O-rings and is made of PLA, it is low-cost and gentle on your mind, environment, and wallet in case of loss. PLA is the same material as so-called biodegradable BBs.
- With a weight of about 5g, the ejection is good. If the main unit is properly adjusted, they can fly several meters.

Disadvantages
- Because it is lightweight, it may sometimes fly out when you rack the cartridge from the magazine with the bolt. This was improved by adjusting the magazine's leaf spring to be weaker.
- The rim can be torn off due to the pulling force along the layer lines.
Some break on the first use, while others last for dozens of uses, so it's a matter of luck. Please forgive this due to the low price.

Notes
- The first time you load and eject a BB, it will be a bit stiff.
It will become easier to load after 2 or 3 uses.
- These are consumables. They are not toys that will last forever. It's better to have these for airsoft games than to lose 600 yen.

Have fun scattering brass-colored cartridges in airsoft games!!! If they break, just throw them away! They're cheap!
Please use them with this kind of casual mindset.
