The B&T CA MP5 receiver uses a new hop up mech that's better than the stock TM model. Unfortunately it's not compatible with TM plastic or CA first gen MP5 receivers. The hopup unit is adjusted through the bullet empty chamber (not sure what it's called, where the bullet casing is suppose to be ejected), kinda like with the G36C.
I picked up a CA rev2 hopup unit for my friend's TM MP5 without knowing this compatibility issue, he couldn't use it so I sold it to aZn_triXta07. Tlak about good timing.
