Original Zastava M70 grenade launcher sight / Yugo AK gas block / Mechanically flawless, but bluing mostly worn off

Demilitarized component in very good condition. Bluing retained at more than 98%.Component is very cleanly machined.The gas port is hardened and designed for 7.62x39.Inner diameter (for the barrel) is 16mm instead of the usual 15mm for AKM.Unfortunately, the plate eyelet for lateral insertion is missing - however, this component is primitive and can be comparatively easily reproduced. Technically relevant would be this plate eyelet to allow the grenade launcher sight to stop at the correct position when opened. If the component is missing, one must open it with care to allow the sight to click into the correct position. However, this component is not technically relevant regarding the core function (shooting). Notes:If you have any questions, please do not hesitate to contact me!Shipping within the EU is possible unless the possession of this component is not allowed or heavily regulated in your country (e.g., in Romania or Belgium).
