Hi, I'm looking for a little assistance. I've been trying to figure out if I should buy a laylax spring for my type 96. Are the springs 7 or 9mm? And should I get the 150sp or the 190sp? I have the asgi upgraded trigger box, but I'm not sure how much it is able to take. I will also be upgrading the spring guide and piston at the same time. I have about 100 dollars to spend on these items. I been doing some research, but I was wondering if someone who is experienced with laylax could help me. Id rather not learn the hard way. I've already wasted money on barrels.
