An on/off adapter and an hpa bottle tank was all I used.  It makes a very good gun into a great gun.

what bottle are you using, Johnny?  I'm trying to piece together exactly how much it'll cost me.  I'm considering it way too seriously haha

If pressure is kept below 1100 psi no changes are needed......

I couldn't find The exact same adapter I used.  This one does the exact same thing.  Hope that helps.

One of the things to remember is that you will have to take your barrel off to put the tank on the first time.  Then you will just fill your tank without taking it off.

OK Jonnyboy.....say I order the ninja tank and on/off.
What do I need in order to hook up to the ninja to fill it?
(I don't have a pump, but do have a N2 tank) so do you know of a prebuilt hose/fitting assy.?

Post by: jonnnyboy on November 29, 2012, 08:52:07 PM
Paul, you will need a "fill whip" that has three fittings.  On one end there needs to be the fitting that fits your n2 tank.  On the other end will be the female fitting that fits the bottle inlet on the rifle.  Finally, somewhere in the middle there needs to be a bleed adaptor that bleeds the line after filling so the fittings can be removed from the gun without being under pressure.

I would recommend you private message Tim Macmurray (spelling) of Mac1 Airguns here on the forum as I believe he makes up the "fill whips" for different applications.  I'm not sure on price but I believe I paid about $160 for a whip to attach to my scba tanks but I did not buy it from Tim.  I didn't know about him then but I highly recommend him now.  He's one of our recognized airgun merchants in the GTA mall and is highly thought of by many on the forum.  He's a great help to lots of us. 

Hope that helps,
joe

The on off valve is optional if you simply screw on the tank it will work with the integral pin valve just like a bulk CO2 tank.  If your using a hand pump with female foster fitting then you don't need any other whip or accessory.  Just connect to the bottle's foster fitting and start pumping.  Ninja bottles can be adjusted for different pressures, the standard is 850 roughly the same as CO2 at moderate temperature.  They also have a SHP regulator, it ships at 1100psi and has an additional ring allowing you to adjust the final location the gage and fill nipple point when tight in the fitting.

Just following up, I've ordered this tank and will be installing it in the next couple days. First observation, the tank is LESS than 2", which is good. Also, the tank is smaller and lighter than a 9oz CO2 tank, which is also good.

I'll confirm how well everything works or doesn't once installed but so far, this looks like the shizz! :)

Confirming, it works very well...

I ordered this tank http://www.ebay.com/itm/Ninja-Aluminum-HPA-Tank-Nitro-Air-13-3000-GS-Series-SHP-Reg-1100-PSI-/170945977925?pt=LH_DefaultDomain_0&hash=item27cd2c9e45 (http://www.ebay.com/itm/Ninja-Aluminum-HPA-Tank-Nitro-Air-13-3000-GS-Series-SHP-Reg-1100-PSI-/170945977925?pt=LH_DefaultDomain_0&hash=item27cd2c9e45)

Wicked Sports is nice to deal with. Evidently, they sell a lot of these tanks to people like us. Number is 813-933-5630 if you want a warm body to talk to.

This tank is regulated to 1100psi (adjustable down) and comes with an adjustment ring to keep your fill nipple and gauge readable. (DO NOT do this with a full tank!) It's also much lighter than 9oz CO2.

I followed these instructions: http://www.network54.com/Forum/113813/thread/1320616282/HPA+QB79+and+78+tanker+conversions (http://www.network54.com/Forum/113813/thread/1320616282/HPA+QB79+and+78+tanker+conversions)

It does require taking off the tank and the barrel. Do so carefully so you don't cut the O-rings (if Mike tuned it, you probably don't need to worry about the rings). Then spin the tank on, loosen the adjustment ring and spin your fill nipple to where you want it then tighten down with the allen wrench.

Slide the barrel back into place and tighten the band screw and the retaining screw.

Then pump it up.

I did, to 3000 PSI. I saw no evidence of leaking. So I took it to the range.

First of all I shot 6o shots. Initially my scope was way off. After sighting in, the RWS HP's were doing 2/10" groups. and the RWS Domes were doing 3/10" groups. I note that after 60 shots I was still at 1800psi (confirmed on the pump). I had figured on only getting 50 shots so this is a pleasant surprise. I think 75 good shots is doable.

I don't have a chrony but my best guess is that the guns is shooting RWS domes at 800fps, maybe a tad more (probably less than 900 fps no matter what). That's plenty of power as far as I can tell (~22 ft/lbs).

I'm pleased, to say the least.

Mebits i would be super interested in actual numbers on your gun. i assume its a MM, have you done anything else to it?
Josh
Title: Re: Somewhere I saw a post about QB79 HPA.....
Post by: Mebits on February 04, 2013, 06:27:56 PM
Josh, it was shooting RWS domes at 799 (corrected--should be 699!) according to MM on CO2. I added air at 1100 psi vs. 850 psi CO2. That's it. I'll be shooting over a chrony soon and I'll be sure to let you know what I'm hitting. I'm super pleased with the shot count and accuracy. I'll be checking how well it holds air but I'm thinking it'll be fine.

I'm about 500-600 foot above sea level here in the Ohio Valley.

My guess is that in real conditions shooting real ammo, the QB is only slightly less powerful than the Disco, advertised numbers notwithstanding. More expert opinions may differ and I defer to them. :)

The weather not worthy right now so I'm probably not going to head out to my paintball supplier for a couple days and he's the one who will chrony for me.

Bubba Z is about to do similar, I think. So are a couple others. I just have to say that this is really, really nice on a lot of fronts. Price, fit and finish, power, accuracy, trigger, fun factor, shot count.

I have a MM tuned qb79 on hpa 1100psi.  shoots jsb's the best in this order.  gets about 90 shots??alot
jsb 14.3  758 fps  18.24 fpe
jsb 15.9  736 fps  19.12 fpe
jsb 18.1  705 fps  19.98 fpe
predator  728 fps  18.83 fpe
kodiak     672 fps  21.16 fpe
for comparison my disco shoots 14.3 cphp the best at 825 fps 21.61 fpe.
My ninja 13cc tank just screwed on the end of the 79.  before tune, on hpa it shot about 11 fpe on hpa.

So often the Kodiak comes up as a good pellet. That's a rounding error away from the best pellet in the Disco. I'm calling this near equivalency, what do you guys think?

Personally I know I need to snag some Kodiaks to test.

Interesting and Thanks for the info.
My MM 79 just got the standard tune NOT the power tune.
Ninja tank standard reg ~850 psi
35 shot string CPHP 14.3 Gr.
Temp. 48 F Humidity 33%
HI 667 fps 14.13 fpe
LOW 650 fps 13.42 fpe
Avg. 659 fps 13.79 fpe
Ex. Spread 17 fps
SD 3 fps

When I ordered it I ask Mike for ~625 fps with a 14.3 gr. He missed to the good  ;D

In retrospect I should have got the full power tune and lowered the Reg. psi to achieve the fps I wanted.
I wanted to keep the 16 mile trip to the dive shop for $6.50 scuba refills down.
Afterwards I found out I could get free refills for a 3 mile trip to the fire station.
Now I am looking into getting a 1100 psi bottle or ordering shims and washers to adjust the Reg. in the bottle I have.
I am learning though. I will get the FULL power tune and back the pressure off if need be from now on. It increases versatility.

fng54  I would definantly send it to Mike and tell him what you want from it.  I dont know what all he did but it is now a tack driver. and will kill squirrels out to 45 yrds with body shots.
jsb's are 1/16 to 1/4 ctc.  at 22yrds (in order i listed above)
Kodiaks although hit hard, shoot about 1/2 inch at 22yrds.
1100 psi shoots a lot faster than the 850 psi.  my ninja is adjastable.  I only shoot 1100psi.

Post by: Mebits on February 05, 2013, 07:52:46 AM
jrinehart,

It looks like the JSB's are going to have to get tried! If you want a bit more knockdown without loosing too much accuracy the RWS Super Hpoints have promise. I suspect that I'll be able to put them in the same hole at 15 yds with a bit of practice and fiddling (I'm thinking I have a tiny parallax problem as well as a rest problem). As much as I like those, I know that they're going to open up at distance.

I'm also wondering if I'm shooting as hot as I'm guessing I am, after looking at your numbers. OTOH, I'm not sure I care. Happy is happy. It's not a willy measuring contest with Disco owners! :)

I am at about the point of suggesting MM put an emblem on these guns after he tunes them. That, or sign them. :)

Mike provided me with the power I asked for and informed me of other options.
The accuracy is as good or better as I am. :D This is the only .22 I have that is operational so it ain't going anywhere.  ;D
I have a 78 I got from C-List that is waiting on parts from Mike. A multi-pump and springer has been ordered. Dang that is 1 AG a month since I joined the board! When does this end?

Did you get the power tune? With the tuned valve and probed bolt?

i dont know if mike did a full power tune or not.  it was more accurate and powerful when it came back from mike.  it does shoot a lot faster on 1100 psi vs 850.  it does have a bolt probe.  i wish i knew how to post pics.  i have some 22yrd groups to show accuracy with different pellets.  jsb's all the way.  fng54 i think you will get what i am shooting simply by going to 1100 psi.

Post by: jrinehart on February 09, 2013, 10:00:07 PM
paperpunch1  sorry if i stole your post.  if you have a qb79 all you need to do to convert to hpa is get a ninja bottle.  I have a ninja pro shp regulator from 1100 to 950 psi.  ( The Bottle comes complete)  paint ball shop helped me out.  this bottle does not require me to remove barrell to put it on. just screw it in. in my opinion hpa  is far superior to co2.
