AMMS (cutoff) underfolder locking lug easy fix

light load · 12-10-2007, 03:23 PM

Guys, I got a really sweet brand new AMMS UF kit from copes for a good price. There was a catch however as I am sure some of you are aware of. The locking lug was demilled by accident on these kits so Roger reduced the price to reflect this. So not wanting to try and locate a spare locking lug. I repaired mine.
I drilled thru the lug shaft end that was cut off with a 5/32" bit. Then got a small washer ,took a spare standard AK build rivit, put the rivit thru the washer, then thru the lug then into the drilled shaft. Then flipped it upside down, on the rivit head and took a drift pin straight down thru the hole in the shaft and peened the end of the rivit till it swelled up but not too much as you want the shaft to turn. At this point if you have access to a welder you can weld over the peened end if you feel it needs to be stronger.Also it is tight quarters so you will need some skill. Mine is holding up fine with just the peened rivit so far.
I enclosed a shot of what it looks like. I think it looks as good as factory. Well maybe not, but good enough for me

Good going Lightload - pretty ingenious!

I was waiting for someone to find a way around this prob, either a new found source of the parts or a fix. Good job!

VALMET_M76 · 12-10-2007, 09:26 PM

Excellent repair. Looks factory.

Thanks guys, That is one thing that is a constant here. A great group of guys

Koyotejager · 12-10-2007, 09:36 PM

Good job. I had to read your fix before I could figure out what it was that needed to be fixed, otherwise I would have missed it.

I didn't see the "before" picture, before!

I added a before shot in the post. That is how it came in the kit. Apparently they de milled a bunch like that. Too bad because the rifle I got was unfired!
I know there is probably one Hungarian in the unemployment line

Not to worry........he works at Century now

Their loss and your gain. That fix is definitely elegant. Like the others said I wouldn't have known what you did by just looking at the picture without reading your post.

Nice job, I had suggested that in the last thread of this problem. I didn't know how it would work out though. Great fix.

I'm almost 99.9% sure that all of the AMMS guns got imported & demilled by TGW

Notime, I just found a small washer that the rivit would go thru in my washer can. If I couldnt find one I was going to go to the hardware store and buy one.
The best bet from what I can see is to silver solder or weld the rivit end in the shaft once its set to give it extra strength. Although mine is working fine , SO FAR. The one thing you have to absolutely watch out for whether pressing the rivit or welding is , Dont weld it fast, it has to spin, or watch when pressing down the rivit , it also tightens up so stop before it gets too solid. If you look on your UF stock assys, those external locking lugs all spin on the shaft. It is necessary for the lining up of the pins.

Just checked out the other posting you guys were talking about. I missed that one some how. When was that posted?

I started that post back on 11/ 12/07. Thank you! For the info.

What kind of receiver are you putting on it? I got some AMMS flats & two NDS-1P. I'm not sure yet what I want to do.

I use AK Builder flats exclusively.

The ones I have are AK Builder flats. Are you still working on yours if not email or post a pic if you will? Thank you for all of the help & info!

I am waiting for my step rail upgrade parts before I do anymore flats

Oh boy oh boy, new stuff for Christmas for me me me

Guess you can tell where I have evolved to on the maturity scale.

Wonder why I have a hard time staying married

notime · 12-12-2007, 12:32 PM

Beats the bars! Both kind! step rail upgrade parts?

light load · 12-12-2007, 12:47 PM

The new pieces for the jig that make the upper rails stepped instead of just flat. Also suppose to make the bottom of the receiver really flat

Would this fix be ok for a nodak reciever?
