AKS triangle side folder.... compliance ideas...

[Jeepers]

looking for detailed pics on the trunnion inside and out of the reciever with the stock in closed , open , and 1/2 way positions .....


thanks .....

Hey nice pic! One good lift deserves another, here's a side view of the trunnion:

pics from Google thanks to whoever took them ....

its looking promising but will take fabbing up a new part more then modding a orig ones

FYI, that last pic is of the commercial 5.5mm trunnion with the slot that is used in conjunction with the trigger block.

One thing you have to realize is that unlike the underfolder, where the locking mechanism stays pushed in until the stock is completely open or folded, the side folder release pops back out as soon as the stock is rotated.

do you know of anyplace that has pics or drawings of that and how they work, my idea is useing a pivoting blocker bar and a pin on the back of the stock that will disengage the safety with the stock locked open ...

Ooh that just gave me an idea for using a center support type sleeve between the ears of the trunnion and a long rivet to give something to pivot off.

As for pics of the internals I have only seen views of it all assembled and cannot for the life of me remember where it was. The link was somewhere in a thread on one of the AK forums. Hopefully somebody else has it.

i am thinking "sortof" the same , but with it pivoting left to right instead on up and down ....

How about a trigger blocking bar that could pivot around a vertical post on a modified pistol grip nut. A bar that pivots around the nut could be linked at the right side to an arm that goes out the rear of the trunnion on the right side. The bar could be torsionally spring loaded to rotate clockwise around the pivot point so that when the stock is unlatched the bar would rotate clockwise over the left trigger leg. Unfolding the stock would push the link into the receiver thus rotating the bar counterclockwise off the trigger leg.

i like that idea more then welding on a pivot point to the trunnion ...

the issue i am running into is how to "force" the operator to have to engage the safety to fold the stock..... thinking ...thinking ...... thinking ..............

The safety blocks the trigger at the right leg. the left leg is available and would allow opening the stock regardless of safety position. There can be a lot of friction in the safety lever so designing something that would generate the leverage to move it automatically could end up being too big.

I was just thinking that if you have something that extends out the back of the trunnion then the operator could push it and fire the weapon when the stock is folded. I'm beginning to understand why the Russian design is contained between the trunnion and receiver, back to the drawing board for me...

ok i need some pics of one complete with FCG installed and safety so i can sort of judge some things a lil better ... will be back at this later tonight gots to get some paying work to get done ... lol

[RustyMacHine]

Just let me know when you guys are done.

ok i think i have the "forced" safety figured out but need to know if this latch is solid and about how far it push's into the receiver before the stock is released

There can be a lot of friction in the safety lever so designing something that would generate the leverage to move it automatically could end up being too big.when i say "forced" safety i mean something that forces the operator of the weapon to put the gun on safe before the stock can be unlatched

I'm beginning to understand why the Russian design is contained between the trunnion and receiver, back to the drawing board for me...this is why i am adding some kind of pin/small block to the back of the stock to insert into the slot in the trunnion,that should prevent hand manipulation of the safety bar

That part is hollow but not the same diameter all the way through. The same part as used on the 5.5mm hinge pin trunnion is supposed to be solid but I have not seen one in person.

As for how far you push it in I'd say about 3/16".

ok guys i think i have it figured out to make it operate like the underfolder mod, thinking along the lines of shorting the spring in the catch adding a short collar around the catch so that the spring will now ride on the collar instead of the right side of the receiver, that will give the room i need on the catch needed to "force" the shooter to have to engage the safety before the catch can be pressed

but really cant go any further with having parts in hand...

damn you guys i dont have a 74 and now going to go have to look for a kit ....lol
