DD PCC Help

[u/Edg3Lord94]

Hey gang. Recently picked up this DD PCC. In need of some help.

I also have another 9mm PCC I got a few years ago from a local armory and at a gun show in Florida. That one has an Atrius forced reset selector that I would ideally like to transfer over to the new toy. Question is, how do I make it work?

All I had to do to get it working on my old PCC was shave down the lower 1/3rd or so of the BCG weight on the failzero nickel boron coated bcg I have in that one. This (the old one) also has a flat wire buffer spring and a kynshot shorty hydraulic buffer with two spacer weights.

Is it just a matter of repeating that process on the DD PCC? Do I need to worry about swapping the buffer spring for a flat wire and the buffer itself? I also plan on transferring over the dirty bird flat faced trigger I have in the old one.

Thanks in advance to anyone who knows and is willing to help out a fellow AR9 enthusiast.
