Missing receiver cover nut on Zastava Underfolder. SOLVED IT

[iakobos]

I noticed that the machine screw seen in photo 1 is missing the nut on the opposite side seen in photo 2. 
 
This is part of the release mechanism for the receiver cover on a Zastava M70 AB2.

Here's the rest of the story.  Century Arms had me call APEX which informed me the only way to get the missing nut was to buy a de-milled Rear Trunnion Assembly W/Trigger Guard for $89.00.  I decided it was time to go slightly redneck and dug through my stash of machine screws where I found the acorn nut you see in the picture.  Looks like a natural.  I added some Lock-tight for security and I'm good to go.

Was this new or did it just fall off after some years of use?

Fell off after years of use.  I bought it used.  It was sold new in 2008.

Thanks for the link.  If/when my fix doesn't work I'll buy one of these.

Got ya, I'll have to check mine for tightness

The nut on originals is staked at the bolt shank & nut to prevent the nut from loosening. If staking a CNC unit be careful of the nut as they are kind of brittle and can shatter while staking.
