What does the box say? The model should be written on the box along with the serial number. That鈥檚 either one of those Cabala/Bass pro shop models or something else.

The PCC model I have came from the Sig Pro Shop like this:

There are actually only GEN 1 & GEN 2 & apparently other up date iterations post GEN 2's that are called GEN 3. EASIEST way to differentiate between both are the different shape slots (cooling) on the FORE GRIPS. U can find more on a SHORT Video from SIG RIFLES SITE. I'VE watched, very informative.

This is even more confusing :) it seem like there LE model without Timney trigger?

Built in August 2021 it seems odd that you don't have the Timney trigger. Note - I am not an authority on MPX though my Copperhead K 4.5 from a much earlier build date has the Timney trigger.

W鈥 means LE version so stock trigger.

The upper is a Gen 3 upper.

Basically, it looks like a PCC without the Timney tigger. Maybe they ran out of Timney triggers and made this.

Now go out and shoot it and quit worrying about it.

The Gen 2 has 4 cooling slots, Gen 3 has 2. The shapes are the same.
Gen 2 has block extractor like in George 16s picture. Gen 3 has smaller extractor
internally the BCG is very different between 2 and 3

The second pic posted is not posted by the OP it鈥檚 George16s gun. Which is a gen 2. The OPs is a Gen 3
When I originally replied I made the same mistake. I had to go back and edit my post to reflect who posted what. Also I commented on that in post #8.

This is after mods and I am getting Timney too. A bit heavy and I will take irons out, plus not sure about 3x.

Wow, that didn鈥檛 take long. You might find that the vertical grip may be totally un-needed. that long barrel and light recoil keeps the PCC very controllable.

Interesting you put on a magnifier. What distance are you planning on shooting?

I like vertical grips on mine carbines, same with magnifier on mine Scorpion 16". even if you are shooting 25-50 yards it is nice to see where is holes are. Also you could shift it out. But this setup is bit heavy and I might reconsider magnifier an irons.
