Thanks for the tips. I am actually not sure if I watched your videos or not, what is the link to your channel?
Im from Sweden, so yes, not in the US

I have tested the gun since the post above and the magazines work with my old magwell, even if the mag latch engages the new magazines a bit to much after firing.
Ill probably get a new latch and adjust it and the old magazines to make it all work a bit smoother. Dont want to have issues with reloading.
The trigger pull is fantastic and I am happy with the profile I have on the hammer now.
It is depressed just past the disconnector and I have eliminated just about all the unnecessary movement and friction.
Ill see if I can get a good picture of it in its current state.
My only remaining problem is getting this gun to reload with 28 and possibly 24 gram loads.
I have now tried with original springs and a lightened front spring as well as a bunch of different gas pucks.
Still cannot make the 27-28 gram loads cycle. Not even close with original springs and almost makes it with the lightened spring.
I have even lighter springs that I can make fit and that will reload the gun, but they are so light I will instead have failures to feed from a fully loaded magazine.
Im starting to suspect the issue is a combination of the current gas block and the modifications I had to do to it to make it fit.
One of the issues with this gun is that the gas ports are offset a little bit from center, probably to much vodka that morning on the production line.
This caused most of them to be partially blocked by the original gas block.
So after removing it a few years a ago I increased the size of them from just under 2 mm diameter to 2.2 mm each just to be sure I could get this thing to run. (I have 5 ports)
However, I opted to install a gas block produced by LAC (Leykom Armory Customs in Russia) to remove the front sight post and enable me to change gas pucks and clean the gas system from the front.
The block is produced for the VEPR 12, however, as I found out, measurements are a bit off. After pressing it onto the gun I realize both pin holes do not line up with the cut outs in my barrel.
The instructions from LAC says to just drill new holes. Im not willing to do that, so I fit it as best as I could with the first pin that actually lined up pretty well.
I had to remove about 1 mm of material to fit the gas tube, but apart from that it was mostly in place. Thats when I realized the cut out in the gas block for the gas ports was not even close.
It was about 1 cm off and completely covered all gas ports. And no, the block is not on backwards, its impossible to mount in the wrong direction due to gas tube lenght and the fact that the threaded plug goes forward
Thus I had to remove a lot of metal from the inside of the already larger block to uncover the gas ports. The original block has a very small internal volume, this block is bored straight through and even with the threaded plug in place it has a substantially larger volume.
I suspect that this volume is large enough to reduce the force of the gas impulse.
Alternatively this setup has reduced gas puck travel, but if that is the case I think it is very minor since I measured it and it seemed to be similar to the original gas block.
My current thoughts are to either construct my own gas block or to just brute force my way through this and increase the port size even further.
I have not decided what path to take yet, but increasing port size is probably way cheaper and easier, with the possible downside of going to far.
