Picatinny Rear Sight Rail For AK Airsoft

This is a Picatinny rail that attaches to the rear sight, made for airsoft AK.
Existing products replacing AK rear sights require removal of the tangent sight itself.

I want to install a red dot sight when playing with others in airsoft and use an iron sight when playing alone at home, so I built a rail that I can mount over the tangent sight without removing it.

Installation was confirmed with E&L's (Arrow Dynamic) AK-74 and tested on a we-tech ak-74.
Compatibility with other companies.

For installation, use a pin vise to drill 2mm-diameter holes on each side of the rear part, referring to the image.
Insert screws through the holes to fix the rear part in place.
The holes should be drilled where the screws pass under the tangent sight.

The front side is fixed in a shape that hooks into a recess in the front of the sight.

I wanted to keep the rails as low as possible, so the middle section has very thin members.
Do not break the support material when removing or installing it.

The thin section in the middle is tightened by fastening the red dot sight to the rail from above it, which is then pressed against the rear sight body to secure it in place and ensure its strength.
