RPK 47 gas tube lever lock

You can get a new virgin lever with the pin after you install it you peen the end like a mag catch pin I'll find where I saw them (might have been r guns) I believe they had yugo ones but might be able to use any designed for a milled ak rear sight base.

If the milled rear sights from other countries rear sights are wider than an akm's just like a yugo (which I believe they are) then you could get a brand new unissued milled receiver east german lever from kvar, also I am pretty sure german ak stuff is blued like a yugo as opposed to black oxided

Could send him an email to check the dimensions. AK Gas Tube Lock for AK47 & AK74, RTG Gun Parts
