QB79 Ninja - The $200 PCP

[wiffle32]

If you do go the Qb route you may want to tear it down and smooth everything out, lots of info online for the how to.

Outstanding.

It DOES appear, however, that AirgunDepot has a shortage of .22 cal QB79's

I am in the process of tuning one up for myself now though I will never get it even close to the qb79 I have that nervoustrigger tuned up.  My goal was to reach 20fpe with JSB 18.1's and with some small valve mods and a good deburring/polishing it seems I have made it.  I shot a full string over the chrony from 3000psi to about 1100psi with JSB 18.1's and got a low of 702 and a high of 714 for 58 shots.  I think with some tweaking I could get a few more shots but I'm happy for now. I love these regulated ninja tanks!
  The barrel already shows promise but it has some crud in it.  I am waiting for an order from brownells now so I can try to polish the bore.  Then it's on to mounting the scope and seeing how it ends up.

Bob is defiantly an enabler, I just got my first pcp "discovery .22" about 2 months ago. After reading about his qb79 ninja, I'm getting a 13ci ninja tank for Christmas and buying a qb79 soon!

You've just crossed over the point of no return.

Mine is here, and so is my Ninja tank. But I can't touch them 'til Christmas! 

That's ok, I'll just shoot and tinker with my other airguns for now! 

[indianarifleman92]

 it's so bad I just put a qb79 .22 on pre order from airgun depot

[WECSOG]

Ok, I mounted the tank yesterday and have it shooting. I only put about 1800 psi in the tank to start with, in case it leaks or has some other problem that would necessitate a teardown. Actual pressure on the gun is the same regardless, but I didn't want to waste all that effort and then have to start over.
Took ~100 strokes of my Hill pump to reach the 1100 psi setpoint, then another 50 strokes got me to 1800.
 
Shot a few rounds into my indoor backstop. Shoots fine, but way to the right with factory sights. Doesn't seem to have leaked at all.

Today the plan is to work on the sights and bring it up to a full fill.

I have two more .22 QB79's on order from AD.

After all my reading this little gun is a true firecracker. For me, mod1 and getting the velocity in the 740fps range with CPHP's is perfect for 30-35 yard starlings and the like, I would be very happy with that .

I have ordered some Discovery seals and ready to give it a go.

This is one of the very best postings on QB79 modifications that a lay person can understand that I have seen !

Great work Bob.

One of my favorite rifles is a 177 cal QB79 tuned by a forum member (nervoustrigger).  He set it up with a RVA,  cock on open, and lopped off a bit of the barrel to fix my accuracy problem.  Uses a standard 850 psi output Ninja tank to shoot  8.4gr pellets at 700fps.  Very pleasant to shoot,  and seems like it goes forever on a full tank.  Partial fills are great too and I use it to get the most out of my SCUBA tanks.

I just bought a AR2079 in .177 that I'm going to set up for accuracy, I have the 4x15x40mm Bushnell Trophy scope with AO already and have the mounts and rings. I will put a Umarex moderator on it to keep the noise down.

Don't think I'll do much playing with the velocity as I'm sure it shoots in the 750-800fps with 8 gr pellets ... way more than enough for my use, I want minute of fly accuracy at 15-20 yds ;-  ) I may try to de-tune it if the shot count and accuracy is not what I think it should be.

Wish the gun was here already !

I bet that is a sweet shooter. He knows his stuff.

Thanks Andy.  Thanks Jerry.  Just standing on the shoulders of giants

Yes I have seen his post and he really knows his stuff.

For me and my skill level many of the things the guys do is is beyond me, so I just sit back and marvel at what they can do.

My demands are not as great as many here and a 700+ish fps QB79 shooting CPHP's is pretty easily done without going crazy. Changing out the breech seal to a Disco, a new Venturi bolt, and opening up of the barrel port should be easy enough to give me the zip I want. If I decide to get more power hungry, I would change the valve.

Same here wll.

I want one as well and already have the regulator so one question does the Pro SHP regulator thread into the QB tube or does it have a adapter block to attach regulator to QB tube and is that block part of the QB 79 package so all I would need is the gun and tank.

Mike

[nervoustrigger]

Right, the QB79 has a tank block that accepts the Ninja regulator directly so all you need are the two things you mentioned.

For a QB78, you have to get a tank block and modify the air tube to accept it.

[Buldawg76]

Ok so the base model QB 79 without the tank for 105.95 on AGD and a 13CI tank is all it takes to be shooting since I have the regulator.

Correct.

[Buldawg76]

Cool, now the problem is no one sell just the tank without the regulator as its a ninja policy or DOT that a tank cannot be sold without a regulator so if anyone knows where just a tank can be bought  or has just a tank they would part with send me a PM as I am in need of just the tank since I have the regulator already so a tank and gun and I am on my way.
