I saw that M92 bump fire video that was going around a while ago and decided it looked fun.  I picked up an M92 for $460 after transfer paperwork, sent off the SBR paperwork and got to work.

It is nowhere near done and needs a lot of polish and paint (duracoat).  The rail for the pistol grip is still a work in progress.  When it is finished I hope to have most of the rail, if not all of it, hidden inside the grip.

I didn't like any of the rail options out for the M92 so I picked up an Aim Sport Saiga quad rail to modify.  It was around $60.



I had to cut, file, and grind on the rail to get it to fit properly.  







I also had to file some parts down on the gun itself.  


















I know the rail looks ugly right now but this is nowhere near what it will look like when finished.  It needs to be reshaped and I will probably hollow out a spot inside grip to hide the rails.  





I also added an AKRBZ adaptor to correct the angle of the stock.  I had to shave a good portion of the AKRBZ adaptor to get it to lay flush on the rear of the receiver.  I drilled and tapped the rear of the receiver for 4 counter sunk screws to secure the stock.  I then added a M4 Stock Folding Mechanism.  It locks up well and there is no play or give.  It has a pistol tube attached until the SBR paperwork comes back.

Looks like an interesting build. What's the deal with the springs in the stock in the first pic?

If it's to aid in the bump fire, OP best delete the pictures and hide his dog.  You can't use springs to aid in bumpfiring.

Dampin recoil

If you already SBR'd the pistol why not just buy the Slidefire stock already made for the AK platform?

I wanted a folding stock, and a new DIY project.

The stock springs are not a good idea legally. Invest in a good trigger.

Yeah I would ditch the stock springs unless you like huge fines and a nice prison sentence...

Looks like a dandy Bigun!!!.....I really like the fact that you can get the most out of what little space there is on the barrel, meaning the full length of rails.

Other firearms have springs in stock, like the tacticool version of Hi-Point carbine:



Graco Cracoil buttplate you can add to many stocks:

Updated pictures of the folding stock mechanism and the modified receiver block.  





I made my own dust cover rail with a 12" rail off amazon for $12.  I cut it, shaped it to fit, and drilled and tapped  4 screws to hold it in place.  I then used devcon in between the rail and top of the dust cover, the threads of the screws, and the screw heads to keep every thing in place.  The bolt carrier doesn't contact the screws.











I'm going to hit the gun with another few coats of mate black duracoat in the next week or so.

Looking good Bigun, coming along nicely.  Thanks for the info & update on yer project.

It's pretty well established that the springs are a no-go.  But yea, whatever, we're all wrong.

I like it! well done!

fixing to start whittling on mine...........yeeeeeeeeeeeeeeeeeeeeeehaaaaaaaaaaaaaaaaaaaaaaaw!!!!!!!!!!!!!!!!!!!!!!!

Excellent work there. Hoping to build mine in a similar fashion one day.
