Need help picking upgrades

[B.A.M.]

I'm going to be getting the Rt ule and i was wondering which upgrades i should get. I have 3. One is the intellaf frame, a ule mainbody, and the ule on/off drop. Do i not need one of these or do i need some aftermarket parts to such as a barrel or barrel pack .

nice choice man, that's all you really need, maybe an aftermarket barrel .There is the option to get the ult kit which reduces the bounce and weight of the trigger.
