We are waiting on a reply from our last response. I need to know where it sits when you add both spacers so we know what length to make the new spacers that we're gonna send you. The spacers are cut on a lathe in a single operation so they should be perfectly square.
Here are the images of the measurements that we based the spacer size on. We measured several Ak's here at the shop and added some length for it to sit off the front sight. I need to know the length of your threads in order to send you the correct spacers.

Below are the measurements I sent in and posted, they should be fairly accurate. I did take new pictures of what you requested with both spacers.
First Picture is with ONE spacer installed, completely bottoms out on FSB
Second picture is BOTH spacers installed
Third picture shows both spacers next to threading
Fourth picture shows MD, spacers, next to threading.
The measurements from my Draco is 15mm, Factory WASR (not parts kit) 14mm , slant back VEPR 15mm.
I measured the spacer at 5mm, I attempted to measure the internal threading of the muzzle device and think I came to 20mm. If that is correct then it has 15mm of threading which explains why the devices are hitting the FSP. I'm not an engineer by any means (computer science major) but possibly a 7-8mm spacer could work and be universal? I'm unsure of PSA barrel thread length but that would have to be taken into account as well since they move allot of volume. Could anyone with a PSA rifle measure the length of their threading?
Please see my pictures here where I did the measurements with my calipers.
