Your HiPac seems to b coming along nicely. Find some time and effort spent on the trigger is well spend (light guns are “twitchy”)…and getting the cheek up a bit has helped my holding/grouping quite a bit (probsalby also due to the light weight).
Think I really need another 2250. Keep farting around with them, turning them into other things, and I kind of miss the basic gun (in my case, would be a 12gr. co2 carbine).
Think I may have to put a WTB ad in…and hope I can just leave it alone and not convert it to something else.
That bulk fill adapter from JDS did you have to get a different valve for your 2250? I want to go that rute.
i have the jds drop tank adapter an my 2300.i like it better than the qb79 drop tank adapter because if you notice the tank block mouting holes are further away from the fill edge of the tube.if misjudge where you put the qb tank holes the gun can have castastrophic failure,it has been reported before the holes fatigue and the tank goes pop.with the jds adapter there is less of a chance of that happening
the other thing with the jds adapter it isnt necessary to cut the tube.what was told to me because the threads are wider than the tube there is less meat there and can wobble the adapter.iirc there is a .030 difference between the threaded part of the tube and the unthreaded part,most likely the reason the jds has a fat o-ring closest to the threads.i chose to cut the threads off so there is little to no wobble with the adapter,i now have a -016 90 duro o-ring there instead of the fat one because both o-rings are now in the tube.for extra security a third retention hole was added to the top of the jds adapter.heres the bad with the jds adapter there is no bump where you install the tank,the qb adapter has a bump in there that engages the air/co2 release pin.with the jds you have to remove that pin or get an inline on/off asa adapter.thats the route i chose didnt want to have to fill my tank while it was attached to the gun.
for the valve i went with a discovery valve no need to buy expensive boss valve parts that route.
all the machining was done by Lloyd s-s of airgunlab.com http://airgunlab.com/
it was a great experience working with Lloyd,his machining work is top notch.fast turn around at the time also.i really feel better about having him do the machining because i have seen the videos and read the blogs with him and his builds as the subject.he knows what he is doing and has the equipment to do it
take a look at my gun you can see where the adapter mounting holes are then look at the pic with the qb adapter.there is nothing wrong with the qb adapter if its used correctly go to the site they are sold there have been some cautions added
heres the pic see how far away from the end of the tube the mounting holes are now look at the qb adapter and where the holes are
the boss valve does come in a 12 gram cart version also taken from the bna website
BOSS Valve: The Boss valve, modified stem guide & 12 gram CO2.
The valve stem and valve spring are unmodified originals. For 2240, 2250B, 2260, 1760, 2300, 2400
you would probably do better to get the boss disco valve and use a 22xx valve face instead of the bulk face.then at least you have the 8-32 retention screw thats recommended and if you want to fill above 2000psi add the extra two retention holes.i guess you could get a regular dico valve and add the 22xx valve face too.someone on here was going to do that and report back,cant recall who that was though.
