Have been watching KVAR for their left-side folding stock trunnion with the forward hinge mechanism for the AK-74/AK-100 series of rifles, but they have been out of stock for months now.  I would like to pick up 2-3  Russian or Bulgarian made sets, but open to any make as long as they are Mil-Spec and not soft metal, airsoft guns part.

Is there anybody else stocking them at this point??  

Thanks for looking!!

AK Builder has a side folding triangle kit with the latch mechanism.  It's not Russian, but it's good stuff.  I have one on my ak-74.

Hopefully I don't get slapped for linking another forum, but this may be of interest to you OP.

Are you asking about the Bulgarian pattern or the true AK-100 pattern?
