Is finally shooting good. After months and months of working on this gun, seems like it's finally shooting really, really good. I bought this gun used and I ended up buying someone else's problems. The first headache I got with this gun, is probably the reason he sold it, the gun was leaking air out of the regulator vent hole. Upon inspecting the air tube, the previous owner(s) some how put a scratch in the tube right where one of the oring on the reg sits. Not sure if you see in to the tube but the threads were also cross-threaded by the previous owner.
The only fix was a new air tube from FX. After the installing the new tube, the "puck" under the air gauge was leaking. FX sent me several upgraded rubber donuts but they kept blowing out and leaking out all the air. Stupid design by FX
The only option I had was to teflon tape the gauge in but this caused me find out a way to plug up the vent hole under the gauge. I had to tap the hole and JB weld a screw to seal the hole. It should be fine using this method because the screw is holding most of the pressure and on top of that JB weld says it could up to 5000 psi. So far its been holding pressure for two weeks and I've shot thousands of pellets:
I installed a Huma regulator and the power plenum:
Drilling a vent hole was nerve wracking but I was able to get it done:
After everything was done, I started to shoot the gun over the chronograph but on my first string, I blow out the pellet probe oring. I looked up oring sizes for all my guns and made a big order and after waiting three days, I was able to install the correct sizes oring (1.5mm X 5.5mm 70 NBR). On my first string, the oring blow out again so installed another oring but again that oring blow out. I install a slightly larger CS oring (1.78mm X 5.28mm 70 NBR) and this solved the problem. I've put hundreds of pellets over the chronograph and these are my numbers:
H&N Baracuda 31 grain. Reg 120 bar. Filled to 235 bar. I could've gotten more shots if I filled to 250 bar but was low on air on my tank.
43 shots at 51 fit-lbs
Hi - 865
Lo - 856
Av - 860
ES - 9
SD - 1
30 and 40 yard groups were hole in hole so I'm not going to show a picture of a hole in the paper but here are the gun's 50 and 75 yard groups
In conclusion this gun had to have been my most problematic gun I've owned but in the end it was worth it. It's definitely a shooter.
