You can build an EXCELLENT 20 FPE .177 cal around this platform.... Using the 10.3 gr. JSB Exact Heavies at right around 900 fps it was extremely accurate and delivered a ton of shots.... enough for an entire FT course with sighting in.... from a 13 CI tank.... Most FT guys find the accuracy is best with those pellets between 880-900 fps....Bob
Yeah, For me the "tinkering/tuning part" is very satisfying, that's why US afflicted tend to go from project to project . With of course, a short break in between. Once you're satisfied the gun is finished, all frustration (if any) experienced throughout the project, seems to vanish.I just need to work on drilling more precise holes with my drill press
Hey Birdmove,1) Yes, Gun, Tank, Fill & Pellets.2) Yes, Single set-screw on top of breach needs to be loosened or removed to pull out barrel.3) Once barrel removed, put small amount of Super-Lube on Ninja Tank seal and screw in.4) You may need to replace the 3 barrel o-rings depending condition, use Super-Lube again.5) Keep tank on gun when filling. I rarely remove the tank .6) Fill tank to 200 bar with hand pump or large tank. I only occasional bleed the tank. To do so, I just back out the 1.8K bust disk slightly - be careful this disk can become a projectile.7) I don't know about the other models, but the barrel needs to be turned and twisted as the three o-rings hold it in place. This is pretty easy. Also, remove rear sight and loosen barrel band.Good Luck
FYI, there is no need for the bonnet to be fully bottomed out against the tank block. Back it off a fraction of a turn until the fill nipple and gauge are in a good position and then pressurize it. Once pressurized, the load on the threads keeps it from rotating. You can put in some shim stock if it makes you feel better but it is no more safe either way.
Jason, I was not trying to infer that the bottle and reg not being fully tight was unsafe...
