So, I have a question. Do you find that your Disco is accurate with the barrel band, more accurate with 2 barrel bands, or have you gone barrel bandless and find not having a barrel band to be accurate? And does anyone have an aftermarket barrel band that is head and shoulders above the stock band?
Anyone and everyone, please chime in.

tko mods a band that works really well. I added it to my discos, on both .177 and .22. helped with poi changes.

Thanks for the input. I will give them a look.

Mine is a double-tube so I use two barrel bands provided by discosrus. JMO but I think the barrel is too thin to float well.

Thanks jimmie lee. But I need better proof. So just send your Disco (and Talon P) to me for extensive high altitude testing. Will have results back to you in a year from when I receive the AG's. You should by then have either forgotten about them or have them replaced.
Hahaha... :)

Don't think I missed any trials.
No band
One band
One band "tromboned" up and down the air tube.
two bands
two band tromboned up and down the air tube X2.
Three bands
Band just ahead of the breech (needs some stock inletting) and one to trombone up and down the barrel.
NONE of them really changed accuracy. Did change WHERE the pellets landed day-by day.
So the barrel band seems more for consitant point of impact than it does for group size. Free floating made nice groups, but I couldn't count on those groups forming whree I epected them to be form day to day.
If I had to recommend one, would recomend ONE BAND and the "6 screw" mod. Besides the top and bottom screw, add 4 other screws. two angling up to the barrel and two angling doen to the air tube. TIGHT to the air tube, just short of tight to the barrel.

Thanks Ribbonstone for the input. Gives me something else to consider.

Is there a preferred place for the band on the disco? I have mine in the middle of the barrel to equally support it's weight on both ends.

Great question. Hopefully one of experts will chime in on this.

This has been my experience, my POI would drift with only one barrel band. It would shoot a nice group, just not in the same place every time. Since I have added the second barrel band, my POI has stopped drifting around. It use to be that every time I took the gun out I had to readjust the scope to get it back on target. It always would shoot a small group, just not in the same place from time to time. Now with two (2) barrel bands it stays on target when i pull it out every time.

I use the 2 barrel bands mostly to keep the barrel in the same position when it gets knocked around while I'm bumping through the woods. I prevent poi changes by filling to 1750 and stopping at 1200.

I was considering 2 bands, but at the time (when my rifle was still .177) I had no problems. Now I seem to have POI issues. But I shot last night and was in the same hole, even though off to right. It may be scope issues, too.

I have noticed a sweet spot at 1800 and I have been stopping at 1200. I am going to get the B&A Max Flow and Dave @ addicted2airguns.com will install it for me (I can do, but he is going to tune the Duck at the same time). I will really be watching my POI compared to my POA, and I hope to get 15-20 good shots, and 10 GREAT shots when hunting with pwr adj fully engaged.

Mine is where it was when I took it out of the box. It shoots so well I'm not going to change anything. ;D

I prefer my 2 "stock" as in factory bands, one where it was from factory and one about 1.75 inches back from end of air tube, May even add a third :o :o :o. Will report back with results of 3.

Thanks Matt. Please let me (us) know if you do go with a third.

MAy not be for you, but this is my most stable/accurate Discovery barrel band set up.
(http://i157.photobucket.com/albums/t50/ribbonstone/Disco/DSCF0013-2.jpg)
One at the rear (requiring inletting of the stock) to keep the arse end of the barrel/breech stable and one at the far end of the air tube ot keep the barrel from wandering around.

I've seen your Disco before and I thought that was ingenious. I don't have the wood stock anymore, I went with a tactical look. Did you have to do any machining to the band to get it to fit around the barrel sleave?

Cut the sight base, band fits in between the two parts.

I was more worried about bumping the barrel and changing my POI. With two bands it all feels much more solid and I have no fear of moving the barrel. It hasn't moved since I locked the second barrel band down. I'm sure using one band is fine, but that one time you bump it during a hunting session.......a second band is good insurance :)

I went with the TKO fix and it works great. Mike T did it for me when he had my Disco in for upgrades.

I went with two barrel bands! Cut the stock away from the air reservoir to "float' the reservoir (air tank),added two set screws to the bottom band to stop movement,and shimmed the barrel in the top of the band,to let it move (the band) without affecting the barrel and POI!

Sweet group. How large is the hole, 3/8" or so? Looks much smaller than dime size if that's the 2" target I'm thinking it is instead of the 3" version.

It's a little under 3/8 inch. That is a 2 inch bull. The Disco's will shoot,with some mods,and the right pellet. This one seems to prefer the lighter pellets best. Ron

Cool beans, Ron. Thanks for sharing. (Welcome to AAA --- Air Addiction Anonymous...LOL!)
