Custom Tokyo Marui Glock 17 Short Recoil Cancel Kit

This is a custom-made short recoil cancellation kit for the Tokyo Marui AAP01. Since commercially available options (specifically, the older compensator-style Accu-Imp) are scarce and expensive, I decided to make a simple one myself.
I experimented by creating a few prototypes using the filament I had on hand and am now selling the ones I won't be using.
The material is PETG with 100% infill.
The first photo shows the product, while the second and third photos show the same printed part installed on my own Glock.
Installation involves removing the genuine outer barrel and attaching this kit. After assembling the main body, insert the muzzle device through the outer barrel and secure it with screws. You can achieve a firm fit by wrapping the outer barrel with aluminum tape or a similar material.
I have performed an assembly test and confirmed that there are no issues with its operation. (There may be minor scratches from the operation test.)
By securing the outer barrel at the muzzle, it suppresses muzzle climb during blowback, and by fixing the outer barrel to the chamber block, it cancels short recoil.
The tip of the outer barrel has a 14mm counter-clockwise thread, allowing for the attachment of lightweight tracers or suppressors.
The design is tight, so some fitting or modification may be necessary depending on the specific firearm. To achieve full effectiveness, you will need to fill the gap between the outer barrel and the muzzle device with aluminum tape or similar material.
Also, prioritizing functionality over aesthetics, the appearance is not perfect... there are layer lines, support marks, and minor printing defects that do not affect operation.
As part of the operation test, I confirmed short-term functionality even in full-auto at 18 rounds per second, but I cannot guarantee durability for extended use, so it is not recommended.
This was made partly as a hobby, and while some might argue that it's better to fine-tune an AAP01 for similar results, feel free to give this a try if you're interested.
