Description
Introduction
For a very long time, I wanted a proper SKS bayonet lug Picatinny solution that actually matched the look and practicality I had in mind. I found nothing compatible with my needs. After spending countless hours searching for something that fit my idea and finding nothing, I finally decided to design my own version completely from scratch.
This adapter was created specifically for users who want a stable 20mm Picatinny mounting platform using existing front-end mounting geometry, but not the cleaning rod channel alignment. You can find other models on my profile.

Features
I offer three models: normal, long and very long
Main Features
- Designed around Tula SKS pattern geometry, suitable for compatible platforms
- Compatible dimensions for both real-steel patterned platforms and replica systems (i.e. airsoft)
Uses both
- the standard mounting point
- the cleaning rod channel for extra stability
Intended for
- modern stocks with cleaning rod support
- setups where the cleaning rod is intentionally removed (look at the photo)
- airsoft accurate replicas
Required Hardware
- M5 x 18 screw ( x1)
- matching M5 nut (x1)

Istructions
To install, the screw head MUST stay on the RIGHT side when looking at the assembly from the rear/shooter position. Installation in the opposite direction is possible but may reduce tightening efficiency and accessibility.
Recommended Materials
This model has NOT been tested under high dynamic stress when 3D printed (i.e. real firearm), but will be in the near future. For this reason, strong materials are strongly recommended.
For high-stress applications, CNC-machined aluminum is strongly recommended. If you are willing to use it for airsoft I think that you can use standard PLA, PETG or similar. I will update this post anyways.
I am a junior designer, so I am fully open to suggestions, improvements and future projects. If you like the project let me know in the comments and feel truly free to boost this project. If you are having issues with the item write a comment as well, I will surely try to help you.
