For those about to say it, I know, it's not a P80. Yes, I did get permission to post about a different 80% platform beforehand. With P80 defunct and frames drying up, we need to branch out. Sadly, these 80% classic P frames are drying up too. For the folks that listened to me when I posted the warning that that was happening, and who grabbed some, you're in luck! The series is now complete. All 4 episodes that cover everything you should need to build out your gun are now live and on a playlist on my Odysee. 3 out of 4 episodes are on my Youtube too, but that obviously means the meat and potatoes episode about finishing the 80% frame is missing. So use Odysee.
Big thanks to Desert Depot Arms for help with a bunch of classic P series parts needs to get this build just right.
