Nice, I might have to try a couple of those.

bige64, Your more than welcome to use my press and jig to bend them

I'm still not doing well in the health dept. but you are more than welcome to use my tools.

Not that you or I would know anything about gun building !!!

Cephus I've used brake line on a couple builds ... ground a flat on one side for bolt clearance and fit it to the receiver as you mentioned. When the center support was in and riveted I put one good spot weld on the center support attaching it to the rivet to prevent it from turning.

Seemed to work alright.

Cephus I have run in to that problem too.I bought some 4mm washers from ace hardware and use a 6-32 bolt for fitting the center support. measure the out side of the receiver at the top rail, tighten down the bolt and remeasure.
that difference is what is needed to make the support longer.
disassemble measure the support length, and measure the support with the washer added. then just remove the extra from the support not the washer. and Walla!!!!! the right length center support.

Ok did a AMD-65 pistol build on one of these new flats yesterday. Only ran into one major problem, the left side lower rail "ejector rail" was WAY to low using the pre-drilled hole in the rail for alignment. I'd never run into that problem before with the old style flats so it had me stumped for awhile on what to do. So I decided to cut off the lower part of the rail with the predrilled hole and use the trunnion for proper spacing and spot welded the rail that way. It was harder to hold the rail in place until the weld but it worked out fine. I didn't run into this problem with the right side rail.

I used a DPHarms flat bending jig and all the predrilled trunnion holes in the flat matched up 100% perfectly with the AMD trunnion, zero egging out of holes required! The top cover fit almost to good, had to use a rubber mallet to help pop it on. The receiver top rails still required some trimming but alot less than the flats without prebent top rails.

I give the product a thumbs up

and the pistol functioned flawlessly when test fired

Can you post a picture of the area around the ejector rail you are describing?

Tom I've found that to be almost the only flaw on those flats. What I do is space them with a drill bit and spot weld them in. Then I drill through the center support hole.

It has been a long time since I started this thread and I have read of a new problem. I hear since the top rails are prebent that when you bend them up they are still up too high and people were having problems with them. So if I ever try them out I think I will just take a long piece of steel and put over them and hammer them down into the jig to make sure they are correct. Have you guys had that experience yet? Is there any pictures floating around out there of a completed build on one of these newer flats?

Bulletboy · 08-11-2007, 11:28 AM

I've built 3 or 4 on them now. Love em!

Wolverine · 08-11-2007, 12:37 PM

Thats great Bulletboy, so no problems with what I mentioned about the upper rails being too high? Also I think I may have mentioned this before but where there is a big gap where you stick the bolt down into the receiver, is there any problems with the carrier popping off or anything?

Bulletboy · 08-11-2007, 12:48 PM

Havent had any issues with the uppers being too high. Actually they mate up with the trunion and the holes are almost dead on, so it doesn't seem like they are out of spec. One of the great things is that those top rails are already the correct width, so no trimming is necessary. I had wondered about that bolt carrier drop in slot at first too. Thought I might need to stick a recoil buffer in there to keep it from popping out, but nope, stays in just fine. The ones I've built on these flats have fired flawlessly right from the start. I think the latest one I did was the one I put that synthetic dragunov style stock on. Here it is;

My personal feeling on this concern is .. it's impossible for the bolt carrier to come out of an AK-47 with the bolt spring properly in place while firing the rifle.

IMHO until I see proof otherwise.

Wolverine · 08-14-2007, 11:32 AM

That makes sense to me. I guess I meant for the top cover to pop off from it in the post you quoted above, I wasn't thinking clearly. Ya know that Kaboomed AK that we are seeing pictures of. There is a guy on another forum saying that the front locking lugs on the trunnions of other AK's need to be inspected on all AK's so this don't happen. Supposedly if there is any wear on them, if they are curved or anything there is problems? I am still trying to learn more on this myself.
