Download the STEP file for the TNA-303X aiming tool using the link at the bottom of this page.
This STEP file is compatible with most 3D printers.
Once you print out the aiming tube tool (show in black below), you simply attach it with an M5 screw and remove once aiming is complete.
There are now three versions of aiming tools available:
- Version 1: the first is pictured below and is limited to being mounted on the left.
- Version 2: this version can be mounted on either side of the TNA-303X (but will not work for the AK-300 since it's too short).
- Version 3: this version is taller and works with the AK-300.
