I just recieved my Panzer Blackhawk Hellfire edition from rbavapors.com first and fore most the black pvd coating is amazing. The threads and inside of the mod are uncoated and the tube itself is high quality copper. I was on the fence as i dont care for copper however this thing is a beauty. The engravings are perfect no mistakes and custom. The button is silky smooth and it hits like a train. Another sweet feature is the drop down pin as we all know real panzers suck when using an 18650. This feature eliminated the need to drop the copper connector pin until it was almost loose now you barely have to unscrew it for the battery to not rattle which also means better voltage. The price was reasonable around 90 bucks and there are only 50 made right now. I reccomend and i will upload pictures later tonight.
