Hello,
I just picked up my new WBP Jack Classic yesterday. It looks awesome. I did notice it has a different FCG installed (LBE) and the Polish FCG is bagged in the box.
Was this done in lieu of changing to a US piston? The FCG is nice but I was planning on a US piston and swapping the FCG myself as I want to run whatever mags I choose (922r).
Looking at the piston and carrier it is so nicely finished I can't even tell where the rivet is. Is it possible I have a US piston and US FCG? What US piston should I install?
Thanks!
