Havent posted on here in awhile. Figured Id share my latest boredom. I wanted to ditch the tank as I favor tube guns. So I adapted a aea 600cc tank, external reg and plenum. Adapter is 7075 aluminum. You have to bore some flow holes in the body and plug a couple things. It also has a tensioned tj .25 barrel, custom hammer and spring stop guide ( not shown). I’ll post finished results once everything is back from annodize. Its also got a custom valve and is ported. 165 bar quick test showed jsb 34gr at 1080fps. Im going to tune it for 880fps for a high shot count. Barrel is 27.5”. Lets hope its accurate!

Thanks! Its not for everyone, but I like how it turned out. Accuracy with jsb 34gr has been great. Havent really done much bench shooting but Ive been hammering walnuts off the trees out past 90 yards with ease. Its a feild gun so good enough!

@vmaxpro How is the weight distribution when shooting offhand? Overall is it slightly heavier now? Mine loves the 34 grainers too. Did you build the custom valve? Nice porting work. 1080 fps is humming those pellets!! Which reg are you running? What is it set at? The way that the gun is constructed it shouldn’t affect your existing reg.

I dropped the reg down to 140 bar. Its an aea external reg. The factory huma isnt being used. The power is coming from the new plenum and 27.5” barrel. Its certainly heavier! But it does balance well. Im 6’5” 245lbs I better be able to handle it lol. Its easily capable of 100ftlbs but I really wanted a pellet shooter Ive got enough slug guns.

@vmaxpro NOW you’ve really piqued my interest. Are you using a choked barrel? Do you plan on doing other mods?

No choke Tj .25 I think 1:22”? Its been sitting on the shelf for a long time I forget lol. I know I ordered it for pellets. Turning down the tp adjuster for hades at around 42ftlbs is almost perfect. The shot count is insane and superb accuracy inside 50 yards.
