sounds like you have overwritten stock GMF's with DSL ones (funny how they didnt have 2 different ones) so your clubs has 2 AP's rather then 1
Not bad, but it's really pointless to have a chassis shape like that if it's for adding a complex spinner on it.You also can directly attach the secondary spinning zteks to the first tribar, save 12kg, add 20cm extenders to the ends of the secondary tribars and double your weapon weight.
