yugo fcg/safety issue

[shortround13]

test fitting fcg parts in my receiver, went with tapco trigger (used in other akm builds) but this is my first m70 build. are there compatibility issues?

when on safe, there is slight trigger play and if I keep playing with the trigger, I can actually get the disconnector *wrong terminology* the sear to slip off the hammer and release it, while in safe. it seems like the safety isn't long enough to sit just above the rear 'ears' of the trigger, thus allowing it to rock slightly while in safe mode.

are there better trigger options for an m70, or should I try a different safety lever?

EDIT: ok...after thinking about it for a minute, i realized that I was testing without the dust cover on, and by pressing hard enough on the trigger it rocked the safety up, releasing the hammer. that part answered, however the hammer hangs on the sear, so I will try to smooth that out, not taking material off just clean it up.

shortround13,
Is this a milled or sheet metal receiver? I got a ORF milled receiver that the axis holes for the hammer was to far forward and caused the same issue.
The Tapco FCG should be fine as its what 90% of builders use without issue.
Check your Axis hole dimensions.
Also with your Tapco did you install the sleeve that goes through the trigger and sear?

Put a weld on the safety and reshape it, probably the easiest and most guaranteed way to address this.

stamped, ak builder 1.5mm flat. I would assume the trigger/hammer holes are correct, but will take another look at it. I can see how too far forward would cause the safety to engage the trigger at a 'later' point in the trigger pull.
and yes, the sleeve/tube is in there holding the disconnector in place.

try the above or try a different safety.

The Yugo is a unique beast in many respects.
The safety is one of them.
As far as I know the Yugo is the only one with 3 selector notches in the side of the receiver due to the dimple in the safety being further back, and lower than a standard AKM safety.
If the safety is allowed to rotate too far upward it will allow the back tab of the safety to travel forward enough to let the back of the trigger come up releasing the hammer (what you are experiencing).

Should not be any issue using a Tapco trigger group in a Yugo (It's what I use in mine), and unless you filed material off the stock safety on the far right side you should not have to add any material back to it to make it function correctly.

I didn't file anything off the safety. I did notice, that the bottom tab of the safety is only 1 length. all my other safeties have a high spot on the right side (coinciding with the right side of receiver) is that standard yugo or did the demil process take a chunk out of my safety?

do you have a template you can share for selector notches on the yugo?

[nicoroshi]

If it's ( the selector) solid (no step) on the bottom, and it clears the disconnector yet still retains the back leg of the trigger from traveling far enough upward to release the hammer then run with it.
I doubt it was damaged during demill.
If the trigger releases the hammer when the safety is up into the notch of the top cover then you'll need to add material to it (unlikely IMHO if using one from a kit).

No template but I have pictures



The top notch should be .2" down from the top rail if memory serves.
The way I locate it specific to the build is to rotate the safety up with top cover installed (no recoil spring but top cover seated all the way down), and align the top of the safety selector with the cut out in the top cover.
Remove top cover, and measure down from the top of the safety to the top rail.
Now remove safety, and measure height from top of selector to center of dimple in selector.
Minus the first dimension from the second, and you have the distance down from the top rail to the center of the top selector notch.
Most I have done were within a couple thousands of .2" (IIRC).
