Any US importers carrying this gun?

[USAFANG6799]

l likely be offering them (among other parts) in a within stock configuration for those interested in extended shot counts and or increased power over the dismally small factory part.

I would be interested in one for increased power.

Hey guys. thought i would add some details about working on these guns.

it has been mentioned before: dont drill to 3/16 to the power wheel. if you did already, expect failure and dont get hit when it blows

do not over tighten the stock screw infront of the handgard. doing so can bulge-in the receiver where the valve sits, will damage rear valve oring and leak during shot cycle.

the solution is to shorten the screw.
since this is a safety concern i thought the infor needs to be shared out here so people will know.

Bill I must say that's a heck of a nice plenum set up you've made there

[darkcharisma]

Wayne, i watched that m10 also but its 60fpe for a few shots vs liberty 40fpe for more shots. you went with a good choice especially at 1/3 the price hehe

Good tip on the screw, going to address that today. Finally getting a decent day here in Missouri and the pellets will fly!  How much of a difference did your valve work make? Can the stock valve be improved by cleaning up the ports and angling them a littlle? Dremel type stuff, or not worth the effort?

Our friend Duy took pity on me and let me buy one of his valves and he know about my problems with tremors..  So instead of just sending me just the valve he had me send him my receiver.. He installed the valve and assembled it in the receiver  WOW !! What a friend to have... I attempted to open the barrel port... Then he said after he makes up a power adjuster that is safely enlarged it will up the speed more !!
  I assembled the rifle last night and was surprised.. JSB 13.65 monsters went from 890 up to 999 fps !! 15.5 NSA went from the mid 700's to 900 fps !! This is also at the factory regulator setting !!
      He also extended to me, to do some more work on it as far as enlarging the passages..
                               Very great asset to the our forum !!
                                       Thanks again Duy !!
                 Now I wonder what a larger plenum would do....

[darkcharisma]

Hey Ray glad to see that result here. i was going to open your receiver ports to .217 to match that exhast port but misplaced the reamer, saw the power gain and stopped there. my offer to open it up is still good as long as you still have that liberty. will send that power wheel Monday for sure.

i reversed everything back to oem except for hammer shims. i tested 14.3 grains at 1109fps with wheel and barrel port at .217 but receiver port at 3/16. i estimated the power loss due to .177 port for nsa 15.5g to be at around 950fps. ts not that hard to get closer to that Ray.

my valve will not improve the .22 in my limited testing. but if you have a bigger plenum, that will change. the 3/16 port and stock valve is good for .22. the oem valve can be improved by using dremel, its very easy to work with. try it

Does this apply to wood and synthetic stocks?

[darkcharisma]

i have synthetic. check yours, if the screw hits bottom but the stock have movement, means you need to shorten it.

Very nice work Stephen!

Really a beauty Steve !!

I too have a 177 would like to shoot the nsa 15.5g slugs I’m currently overseas will be home April 8 bought the Liberty back in December and haven’t shot it yet. Want to shoot slugs as I already have ordered the slugs. What do I need to do to get to shoot 950? Thanks

barrel port .150x.188. power wheel port .188. exhaust port enlarged. look at oem valve...ignore the cross trench, the exhaust channel is occuppied most by the valve pin. needs work. angle it and everything.

oem valve will not give much duration compared to the one i made. so you need to up the pressure of the reg and shim the hammer spring. or make a heavy hammer.

get on Billys list. that will be one of must items for power

[SoCalZac]

Put me on the list for a plenum.

Billy’s list? What drill size?

[darkcharisma]

I’m down for one😎

i think you would be second on Billy Rohm's list for plenum if hes keeping one. its 3/16

Billy my friend dont let me beat you to it brother lol. i have a piece of 1144 already profiled. just needs to decide oem metric or 1/2-20
