I got this QB79 action on the board and have been planning on making a stock but just couldn't seem to get around to it. So I posted and Rob Roberts sent me his extra one for free. Great guy! But it was the old style and a bit short of LOP for me so I ordered up one of Stephen Archer's blemished stocks for $19. Trouble was he didn't have any 79 stocks only 78s. So I got around to it this afternoon and with a saw and a dremel here's the result. I think it looks pretty good but of course isn't passing as a Rapid but for about $65 it is pretty cool. Tomorrow I"m going to sand and bedliner the bottle and stock. Next up is a tune as it is only shooting 650 fps. I tuned up a 78 with notes from CDT's website and got it up to 730's. I'll post pics of it in bedliner but being realistic if I say I'm doing it tomorrow you might see it in few weeks ;-)
P.S. The cheesy Gamo scope is going!

Hey Andy,
Could you post some pictures of the inletting you had to do on the stock for the gas block and how it looks without the bottle? This is a project I have been thinking about and wondering if it is within my skills. Your stock looks nice and even around the bottle; just what I'm hoping to be able to do.
Thanks, Joe

Fantastic!!!! I'm going to need a whole lot more pics of that baby.

I used a pull saw to cut the stock and then used a belt sander to give it a curved in look. I did the rest using a Dremel. While I started out with a bit I quickly realized the wood was so soft that the large sanding drum that comes with the Dremel kit made quick work of the wood. It also gave a smoother finish than using the bit. If I would have used the sanding drum, the inletting would have looked better. You don't see it anyway.
Here's some top and front views.

Here's some top and front views. The groove at the bottom of the inletting is a channel to provide clearance for the burst disk on the bottle.
The last picture is of the modified QB78 stock versus an OEM QB79 stock.

Oh, here's the last of the pictures. You can see the measurements in relation to the stock hold down bolt hole. It is 3.25 inches back. The other dimensions as shown in the picture.

Nice. I like the QB78 I just bought and someday plan to 'hop it up.'

Ronbeaux,
Stayed up a bit later last night to get three coats of bedliner on the stock and bottles. Boy that stuff dries fast!
So here it is and I like the way it turned out. The bedliner is easy to shoot and since it dries fast you can get a nice good durable coating. I reinstalled the LDC and was up and in business. Shoots CPHs the best and the tune is next.
I think the next project is HPAing one of these.
Oh, so I'm in the garage and hear a ruckus out in front of the house. I came up the hill to see a police car with lights flashing and some people standing on my driveway pointing. My two dogs were barking up a storm. So what do I see but a sick racoon wandering around in the street. This poor guy was obviously on his last legs at 8AM. He wandered for 30 minutes back and forth, stumbling and looking like he was about to die. Several times he arched his back, looked up to the sky and raised his right paw as if to say take me now. It ended when the police couldn't wait any longer for animal control and took him on my front lawn with a bolt action .22. It took three shots to put him out of his "misery." The police were waiting for the "right shot" on the grass. I offered some subsonic primer only .22 shells but they had to use "police issue ammo." Geez official issue .22?
I was going to offer up one of my .22 pellet rifles including the Career but thought better than to draw attention to the aresenal in the basement! I was dying to take care of this myself but my long term benefit of remaining unkown to the police prevailed. Damn what a conumdrum!
Anyway here's the pics...

I really like the way that turned out!!! What size of bottle is that? Is all you have to do is buy the adapter and then get a larger bottle? If there isn't a paintball place near, will a welding supply place re-fill it??
Sorry for all the questions, But I am mostly a spring gun fanatic, at least until I got the QB!!
I've been down the PCP road...........

That's a nice looking project gun, Andy :)
**Edit** - What brand of bedliner did you use? I like the texture.
-
I think you are on to something. This simple conversion looks WAY better than the standard QB79. The extended front (done as well as you did) makes all the difference. Nice work.

andy,....my compliments on a genuinely sinister looking transformation !! i also wanted to take a moment to thank you once again for all the time you spent pm'ing me regarding my qb inquiries. although ive yet to pull the trigger on the qb79, rest assured your latest creation will be the motivation to do so..!!
-
Picked it up at Murray's / O'Reilly's autosupply. I put three coats on the stock and two bottles and it feels like there's still 2/3 left in the can. Guess I'll have to pick up another rifle destined for bedliner! It worked better than I thought it would and looks to be a very durable finish. Great for a field gun!

Ronbeaux,
I picked up 4 9 oz Brass Eagle Flame bottles for about $26 shipped on a really awesome deal. At the time I had no use for them but now I know what I'm using them for! The fit perfectly on the gun without any adapters. Just screw them in. It is a tight fit but they don't rub the barrel.
IIRC it is $0.25/oz or $2.25 for the fill. I can shoot forever with a tank. I'm guessing around 400-500 shots.
I'm thinking of doing another QB79!
-
Nice Job. Stock looks a lot nicer than the issue stumpy one and it's nice to have some place to put your left hand besides bare-cold metal.
For whatever reason, the pcitures just started working for me....had looked through out the postings, but until just now, got nothing.

Today was the QB day and I shot the QB78D tuned by MM and the QB78 tuned by me. The MM rifle in .22 shoots 720 fps! My .177 shoots about the same. What black magic does that man do to these rifles?
I think that the stock QBs are too short of LOP and too barrel light. Putting a RFM shroud on the MM rifle helped and if you look at the picture of the one I tuned you can see I put an RWS brake (slightly modified by me ;-) ) and a spare AR2078 barrel weight. I think doing that on both helped the balance. But the QB79 with the 9oz tank is even better. I think it makes for a very well balanced rifle. I'm digging it so much I think another is on my short list.
Hope you enjoyed the thread as much as I enjoyed doing this project!

Okay I just bought a Tippmann collapsible stock on eBay for $12 shipped. I couldn' resist a deal.
My idea is to see how I can fabricate a pistol grip and collapsible stock. Of course it will be in bedliner black since I have the rest of the can of Duplicolor. I'm trying to think of a way to make an "AR" looking stock with a top carry handle. Might be too much fabrication but I'm going to think about it for a few weeks.

OK, call me stupid. But I see a brass looking fitting between the bottle and the reservor. If I unscrew the cap on my 78 and screw on a bottle I can't think of a way that the c02 would get in there. There must be a replacement cap for the original that will allow the bottle to empty into the chamber.
Please forgive me. Spring guns I know. These I don't.

Ronbeaux,
You must have a QB78 which is either carts or bulkfill. This is a QB79 which is made for bottle. I does not have the gas tube like the 78 but instead it has a gas block. That is the squareish looking thing on the end. The 79s are thus much shorter in forestock than the 78s.
Yes the brass part is the valve on the bottle. I should have painted it too. Maybe later. So on mine I have to screw the bottle in and then place the action in the stock because there is no room for the burst disk to spin. That is why in the pictures you can see I grooved out the bottom of the forestock for burst disk clearance. Luckily removing the action from the stock is very simple on the QBs. Even simpler if you disable the safety, which I don't.
BTW the other two in my last picture are QB78s on bulk fill. I can either charge and go (about 20-30 good power shots) or use a paintball remote with a separate bottle for many more shots. I just don't like having the coiled hose and bottle strapped in a fanny pack. The hose tends to make holding aim harder.
Hope that helps.
Andy

Had to use a Talon SS, but it’s definately ARish.

That is crazy cool. Okay now I'm convinced I need to do something like this. So what is in the mag? Is it just for looks and how did you attach it?
Thanks for sharing. At least it confirms I'm not the only one 'out' there!

Mag stayed on for about 10 min....decided that having my neighbor call the police and getting shot by a SWAT team wasn't going to be real productive. I'd advise you of the same thing: make them look real enough and you're likely to be treated as if they are....not healthy.
Mag is a plastic dummy mag from my nephew's air soft, held on by an interna; screw (using one of the Talons existing screws) and a hidden "tab" locked in place by the fore arm.
-
Hmm, good point. Unless I want to paint the tip orange I should stay away from making it too realistic. Okay just going to go with a pistol grip and the adjustable stock. Got some ideas brewing in my head. Just have to look for a donor action.
