My buddy Tim and I joined the Polarstar club, and it was a completly custom build.
I present our Polarstar Type 97's
the trigger pull was shortened quite a lot, the fire selector is now a micro switch just in front of the trigger and i installed an ambi mag release so i can remove mags with my left hand now.
The work was done by a local tech named Mitchell Fleury, the guy did an amazing job, this thing is nuts!
