Feedneck thread type for B2K4??

[psychoballer93]

Ok, i just got a B2K4 PDS in a trade. Iwas wondering what type of feedneck threads(besides ICD) are possible on this gun. I realy want a Function neck.:)

[Vague312]

you can try angel. They seem to work the on promasters well

ICD is what they're supposed to have, but Impulse threaded feednecks also work, not all the time though.

80% of impulse feednecks fit

All impy feednecks work, but you dont really want to take the feedneck out once you put it in.

The Impulse threads are just a hair smaller than the ICD ones. The threading on the ICDs is a fractional inch (don't remember it off hand), and the Impulse is a rounded decimal inch that just slightly differs. The Angel is a metric sized diameter, but has roughly the same thread count. I've known some people to be able to force an Angel feedneck into well-worn threads before on Imps and Bushys.
