I removed this drop block, regulator and tank from my Notos. I was filling to 3200 psi and getting 60 shots before dropping off the regulator. The aluminum tank is rated for 450bar so going to 250bar, Notos max pressure. The tank is 0.25L or 12.81 ci. The take has a 11/23 date. I had to file the edge of the tank to not hit gauge when screwing regulator in tank. Regulator is 1800psi out put. Drop block was purchased on eBay. I decided to go back to the regular setup as l found the tank setup just didn't work for me. I REALLY miss the shot count, as filling every 27 shots is a pain but l prefer the ergonomics without the tank. I will take 110.00 shipped to lower 48. PayPal, you pay fees or a USPS money order. Thanks Don
