I've checked Noobie's M-trigger and it looks it's pretty much the same.
Even the internals look similar (someone posted a picture of it disassembled), the ratios of the levers are different though. However mine doesn't have magnetic return (just a spring), and only the piston sear and the spring guide pin are stainless, everything else is made out of delrin (POM), the sides are aluminum.
The stock does look bulky in the pictures, looks a bit smaller in reality. It's not that big either, the rear section is 11Ã—3,3 cm. It will be shortened and a foam butt plate still needs to be mounted. It's not really comfortable since the spring pull is 20 kg (44 pounds), but it should be better with foam.
Yeah the magazine is exactly where you rest your hand, but it isn't too bad is you put the magazine on your palm and wrap your fingers around. This one will stay as it is, as there would be too much modifying needed to change the magazine. When I build the next one, I will post the design here so you can all give me ideas on improvements.
The AEG bucking is way cheaper and VSR buckings are difficult to obtain here. Also with a proper design, an aeg bucking should perform pretty much the same. Also because of the barrel. Don't know if I can even get a vsr barrel here (not cheap for certain).
The ball is 25mm and I think it's the same as on the L96. It doesn't look that bad, does it?
I prefer the ball to a enlarged handle as on the vsr-10.
I still need to figure out a way to lower the fps (without too much modification), so it can be field legal. I'm guessing a longer air brake. I wonder how silent I can make it.
