Ok so I bought a matrix vsr-10 upgrade set that had a piston, spring guide, and spring. I also bought a new cylinder that said matrix vsr-10. Then I got the matrix snow wolf vsr-10 to put the parts into, the upgrade parts are to big. I don’t understand why they don’t fit. Anyways right know I have a m-150 spring, action army hopup chamber, action army 6.01 barrel and maple leaf. But I have the stock piston, spring guide and cylinder. I want to get a new and better one but don’t know which one will fit. Any suggestions that you know will fit in a vsr-10 snow wolf?
