QB78 Deluxe .22 cal POWER TUNE BY UltimateAirguns

@ImprezaAlex my rifle has a custom machined valve body and valve stem that we make in house.. Also various other things like barrel & Bolt Probe porting, hammer spring adjustment etc..

@RM85RID3R well there’s a number of things we do to them.. From drilling out the bolt probe, barrel port, polishing the striker, and custom machined valve and valve stem..

@GTRaiDer Out of the box they have enough energy to take a rabbit.. After mods they can take rabbits at extended ranges.. My own QB puts out 40ft/lbs which is plenty of energy for taking rabbits, squirrels,crows humanely.

Got two QB’s a 78 Deluxe and a 78, Deluxe pulls 11.85ft-lbs and the 78 pulls 10.77ft-lbs both with 21.7g Bisley Magnum .22 pellets, 12ft-lbs is the legal limit here so no more tweaking for either, although there still is alot of room to do so.. .

Out of the box they’re powerfull enough to stop a rabbit, and yes out of the box = garden gun. Once tweaked I’d be inclined to disagree.

out of the box will this gun kill rabbits (i know the power varys)

@GWR4079 no! lol you don’t need steel pellets.. a lot of people are very misinformed with this stuff. You just shoot it like you normally would.. Also, it’s not a Co2 bottle, it’s HPA(high pressure air).. At full charge it will blow right through a 2×4 with 28gr eun jin pellets… I`ve taken squirrels at 75 yards with complete pass through..

@GWR4079 well I usually operate the rifle while it’s attatched to a bottle via remote line. Since the maintube of the rifle isn’t large, shot count suffers at these power levels.. this is why the bottle with remote line is a must.. For hunting you could charge the rifle from a bottle but you would probably get a few power shots before it falls off and needs charging.. There is a PCP tube available that’s longer and has more wall thickness.. That would give you more shots per charge.

@GWR4079 well I beg to differ with you about the QB being a garden gun.. lol In it’s current configuration it’s output power is around 40ft/lbs, it will shoot a 28 grain pellet at just over 780 fps.. that’s more than just a garden gun.

i can get a QB78 Deluxe 4 £95.00

Yer I too would like to know where I can get a pressure gauge cap … Plz tell us if u know .

@mrsuperterd co2 can reach pressures of over 1400psi depending on temperature.. The tube in these guns are engineered with a safety margin, they can handle over what they’re operated at.. We have NEVER had a problem at 1600psi.. We have tested our qb’s up to 2000psi and never once had a failure with the stock tube BUT I’m not suggesting you use that pressure.. 1600psi would be fine.. I’ve have not heard of or read of one failure that was under 2000psi.

@luisfitty Our co2 rifles will shoot 800fps on c02, mainly due to our custom made Magnum Valve.. 730fps on co2 is good but temperature at the time of testing is important..

@ganymedeIV4 Can it Gany! wat do yoou have against england?
