RE: javpcp I have a seperator on order, but the bleed off works surprisingly well. I've used it twice, from 160 to 280 Bar around 10 minutes... It slows down around 3000-3500 PSI
I got the butt hook and the mono pod on eBay-UK. The Bag rider is aluminum gear shift handle I bought on Amazon and fit with hardware from Ace (through the large hole on the lower part of the RTI butt plate. The bipod is a UTG Recon that I took apart and added washers to keep it from swiveling. I got the angled picatinny extension for the bipod on Amazon.
