Ill be extra careful with the mech. If I have to remove the gyro and put it back so be it. Or I can run this contract with 3 and hope I get enough to replace the gyro I didn't have money for. Assuming gm will allow it.
Dons GM hatAllow what? This is between you and the CO. Everything you're doing is rules-legal. The CO cannot help you buy buying you spare parts, nor loaning technical support, nor simply giving you a unit so you can rip it apart. But the CO is allowed to
loan a unit to a Lance Leader, and while in possession of that unit, the Lance Leader can do what they want with it as long as it comes back in equal or better condition than they got it (or if it gets legitimately blown up during a combat operation; that's a known risk). So while the T-bolt is in your possession, you're completely within the rules to take the gyro out of it.
