One other thing I'd like to show you is the fill system I have.... I bought the parts from China on eBay for just $16.00, it will allow me to fill the gun from any paintball tank with a 1500 psi regulated output.... It consists of a fill station valve with 3000 psi gauge, an 8" braided hose, and a slide check which came c/w a female Foster fitting.... I bought the three parts separately and the vendor combined the shipping for $9.00.... and I received it in just a week....

Lots of great lore and sharing here - being a retired engineer stuck on my back for a month or two now, and fairly new to the airgun hobby/addiction; this is such a good crash course, I've started to lust after my first pcp.If someone wouldn't mind a simple question, what are the exact O.D. (14mm?) and length of the XS60c PCP .22 barrel? I'm thinking I want a 24" match barrel, since it has to be pulled for the repeater mod anyway. If I use a tank I'd rather use a turnaround block and maybe a longer plenum (why not make an .083" 4130 tube?) and use the slightly longer (22ci)regulated tank? Not knowing dimensions I'm not sure if that's feasible. Maybe someone wouldn't mind shooting a pic of one of these guns against a yardstick or something?Thanks-Rod
The barrel on an FD-PCP is 14.5 mm diameter (15 will clear the tube no problem) but the part inserted into the breech is about 1/2" (and a poor fit).... It is about 21" long.... If you get an LW 15mm barrel (23.8" LOA) you can turn it to fit the breech.... I developed the reverse tank blocks, and despite having tried to give away the design a couple of time, no enterprising machinist is producing them.... For a .22 cal shooting, say 35-40 FPE you can get a large enough plenum with a 13 CI tank.... If the back of the tank was at the front of the receiver, the plenums would be about 43 cc with a 13 CI tank, 57 cc with a 17 CI, and 80cc with a 22CI.... Unless you want the larger tank for a ton of shots, I would use a 13 CI for .177 or 22 cal, a 17 CI for .25 cal, and a 22 CI tank for anything bigger.... A 4130 CrMoly tube that is 7/8" OD x 0065" wall is plenty for 3000 psi working pressure, no need to go thicker.... although it would increase the strength of the threaded area (if you still use the threads)....Bob
If it leaks you can fix it.If this idiot can, so can you. If you could disassemble the gen 2 and get some photos that would be great. I can't be the only one wondering exactly what changed inside.
