OK Lets see the different and many mods that can be done to this great gun.

Actually, I’ve very happy with my plain looking Discovery, but realize I’ve been pharting around with it for several years and have had time to get the little kinks out of the system.
Looks pretty stock.
(http://i157.photobucket.com/albums/t50/ribbonstone/Disco/656a65a6-2b87-475a-8e3a-8fba19c86556.jpg)
1. 2 screw mod (tried the 3 screw mod and removed the 3rd screw)
2. Lighter weight striker (this one done by grinder/file rather than lathe):
(http://i157.photobucket.com/albums/t50/ribbonstone/HiPaC/54835852-a342-4dd0-b35e-0b6120423609.jpg)
3. 2nd barrel band inletted into the stock at the rear (Challenger PCP idea).

(http://i157.photobucket.com/albums/t50/ribbonstone/Disco/DSCF0010-2.jpg)
4. TKO
5. Simple power adjuster (spring guide and a headless screw in the supplied threaded hole in the end cap)
6. Slightly reduced transfer port
7. polished chamber throat/barrel transfer port (removing burrs)
8. 6-screw front barrel band (bottom 3 tight to the air tube, top 3 just barely slack to the barrel).
(http://i157.photobucket.com/albums/t50/ribbonstone/Disco/f23e4f17-3bcd-4a83-a9a5-a7668162173f.jpg)

Typical accuracy:
(http://i157.photobucket.com/albums/t50/ribbonstone/Disco/dce29edc-f813-4d13-9f9b-55832f6aec8d.jpg)
Shoots some pellets better, some worse, but this is about the average.

Got mine from a member back in 09, Bushnell scope, TKO trigger, LDC and power adjuster (http://i210.photobucket.com/albums/bb138/dk1677/Disco.jpg) (http://s210.photobucket.com/user/dk1677/media/Disco.jpg.html)

Oh my, where to start,
1. BNM Multi-shot Breech w/shroud
2. 3000 PSI Mod - High Tinsel Screws holding valve (10x32)
3. Power adjuster
4. Spring Guide
5. Regulated at 1800 PSI ) thanks to milo74 for the custom regulator.
6. Blaster Stalk
7. Reamed out Pressure Gauge Block for better/more air flow
8. opened Valve port and barrel port {more air flow)
9. 3 Screw Trigger Mod.
10. New sling swivel studs, on all my guns.
11. 3000 PSI Gauge.
12. 2nd Barrel Band
13. Almost forgot: Disco Double Tube Kit
I have over $1000 in this Disco with the 6x24x56mm Scope and rings. Please don't tell my Wife....
Full power she shoots 25 to 30 shots at an average of 920 FPS with 15.9 Grain JSBs, 3/8 to 1/2 inch groups at 50 yards consistently.
Everything except the regulator came from Norm at Discos R US http://discosrus.net/ (http://discosrus.net/)

And here is mine. LW barrel, 22ci air at 1500 psi, and replaced barrel guides for breech hold down and barrel alignment. Most of the internal modifications done, and shoots 18 gr .22 pellets at about 900 fps. New stock is a bit ugly, but is fitted for my use.

Lots of fun to build up to just what you need!

All my Disco needs is Air, Pellets and Love...
(http://imageshack.com/a/img633/6233/0AnAvm.jpg)
Mine is almost identical to Ribbonstone's setup:
Early (lightweight) Discovery Hammer Spring. (Not really a mod... this one came with it originally, but newer guns are better off with it, IMHO)
Three screw trigger mod (Ribbonstone is right, the third [sear] screw doesn't get you much).
Ron Saul's Trigger (Airgun BnA) - less flex than the stock trigger.
Dual Barrel bands; Front Band has Five Screw Modification.
TKO
Put a UTG 3x12x44AO (Fixed at 5x) with the highest rings I could find.
The Results:
(http://imageshack.com/a/img540/6913/iMt1HN.jpg)
Distance: 15 yards (measured) from the muzzle of gun.
The Top left group was the first group shot in the session with H&N FTs, the remainder were H&N FTTs (Top to bottom, left to right): Notice the groups tightening up as the barrel "seasons" from FTs to FTTs. Amazing what a difference pellet selection makes...
Given the intrinsic accuracy of this particular rifle, I may revisit "Optically Centering" the scope seriously...
I also have a MAC1-Tuned Disco in .177 which is nearly identically-configured (everything except the 5 screw Barrel band mod - it has the band, but not the screws) and it has a MAC1-supplied RVA.
The only outward difference between the two is the RVA, the Barrel Band mod and the color of the bolt handle (.22 is stainless, .177 is blued).

Here is my latest Build.

Benjamin Discovery .22 PCP Full BNM Setup. 10X40X60 ZOS Scope. Boyd's SS Stock. JDS Airman Bottle, Adapter & Regulator, 1600 psi filled to 3000 psi 60 + shots 1holer at 35-50 yds. Best with JSB Diabolo Exact Jumbo .22 Cal , 16.83 gr.

It's hardly a disco anymore. But have the tube, hammer and valve. And the BNM breech.
The rest is all custom stuff. On a good day it does 1/32" groups at 37yds

Ok guys, some of these are no longer discoveries, they are custom works of art..
And makes mine look like a tinker toy..
-
how much $$$ do you guys have in these??
-
Not including the gun, about a grand (including scope, new trigger, and stock) on mine I would say, plus a bunch of tinkering.
-
how much $$$ do you guys have in these??
More than they'll admit to their wives! Lol
-
wow, any one spend more than him? :o ;D ;D
-
How do you put a value on love and art? None of these things are about money: they are about the journey to achieve something.

Well...I guess I should get in on this---with a tac Disco:
(http://i1302.photobucket.com/albums/ag124/josephb1969/IMAG1637_zps9fc13b99.jpg)
Not as pretty as most, but very utilitarian.
TKO
Valve opened up courtesy of Mike @ TKO
Blueforks Design trigger
HPAsports Tippman stock adapter and RVA
Dual barrel bands
P-Rod gauge and block, foregrip
1/4 vinyl tube xfer port
Polished/lubed hammer (polished/lubed the tube where the hammer resides)
Stock hammer spring
Topped with a BSA Contender 4-16X40
It started as .177 and morphed into a .22.
I get my Pro Chrono tomorrow, so I will have shot strings, avg fps/fpe, and I will tune for accuracy. Right now, getting 40 shots from 1900/2k psi down to 1200 psi with RVA in 3.5-4 turns.
Oh, yeah---about 450.00 in it right now.
Joe

Mine?
I got in a trade, for a custom 2240 I built.
I probably have $3-400 in mine, but the original owner put over $1000 in it,
and it is nothing compared to some of the ones I see here..
(http://i59.tinypic.com/2wh16dh.jpg)
-
Not including the gun, about a grand (including scope, new trigger, and stock) on mine I would say, plus a bunch of tinkering.
I'm about the same but I don't include my scope. Prior converting my gun I did a lot of mods that brought up the cost of my build.
-
I didn't get a scope in the trade.
The $1000 was without glass.
This one is a 6-24 I got at a pawn shop for $30
-
Was wondering when someone would mention that most of these airguns are no longer Discos. They are all really nice. In fact, I'd trade my stock Disco for some of these custom jobs. TKO and swivel kit is the only thing added.
-
Depends on what you mean by "Disco"
In my book if it retains the soul and the drawbacks of the system, then I think it's a Disco.
If the action is from a disco (tube/valve) It's a disco. I would love a bigger hammer, better breech attachment, thicker barrel sleeve in the breech, etc etc.
But I have to work within what the Tube allows.
Now if you define a Disco by only modifying the stock, scope, and in general just modify what's originally on it, then certainly most of these guns are not discos anymore.
-
some real nice disco's heres one of mine (more bling than serious mods)
spec is gmac brass breech and tube cap
m-rod trigger
stace bands
chongman bolthandle
filler cover i made
brass ldc adapter
geordie walnut stock
also now has a john small brass m-rod trigger(not shown in pic )
the 2250 with the hipac will be modded to have a shortened disco tube and robert lane reg fitted when i get time and i've a pistol gripped straight stocked one with a reg in and a bnm breech on the go at present but have been too busy with work to do more testing

Mine retains the factory tube, gauge and block, barrel, front & rear sight,(not that I use them) trigger guard, and safety.
Beyond that, not much..
But when you read the side of the gun, it does still say Benjamin Discovery.
I wanted a repeater with lots of shots, and a shrouded barrel, so I got a Marauder.
For a lot less than I could have bought and modified a Discovery for.
I build custom crosman 22xx guns, so I understand the addiction to building and tinkering.
Could I have built the disco into what it is myself?
Yes, but it would have been cost prohibitive.
I can't see talking a $200 gun and changing every part on it spending over $1000 on it.
When I could get a factory designed gun that performs close to my intended purpose then do slight mods, for a lot less.
A friend worked for a audio company that was giving away a car with a full blown kicker audio system as a grand prize.
They bought a Renault LeCar.(this thing was so cheap, it only had 3 lug nuts on each wheel)
The stereo they installed was 3 times more expensive than the car was.
Yes you can take a cheap car, put a lot of money and time in it and make it into something really unique, that YOU love, but in the end, when the next owner is looking to buy it, it is still a cheap car..
-
I think some people, like myself, love the tinkering, the experimentation with a inexpensive platform.
If I was only in it to shot, I would just get a good gun and call it a day. But for me, coming to the range and competition and giving Raw, Daystates, FX, Mach1's a run for their money with a Disco...is just cool.
-
See tomg, there are very few other airgunners in our area that shoot publicly. (But thanks to GTA we have found about 4 in our area)
So I don't get to shoot with them too often.
I DO enjoy going toe to toe with the powder burners at the local range.
I will stand there and shoot any anything they do out to 100 yards .
And I do it with my disco, or my $140 Bam B50.
And sometimes with the 2240's I build.
At 50yards and less none of them will even try to shoot the small things I do, such as empty pistol hulls and shotgun shells at 50 yards, and empty .22 hulls at 25-30 yards.
Their rugers just can't keep up with the accuracy.
I was pumping my B50 one day after taking 40 shots (about 2 minutes and 40 pumps on a 1500psi fill)
One of the rimfire guys made a comment about my pumping as he was packing up his rifle.
I asked him why he was quitting, he said due to the .22 ammo shortage, he rations his ammo, and he had shot the .22 ammo he had brought to the range. (50 rounds)
I asked him why don't he reload his .22's
He said you know as well as I do you can't reload .22.
As I settled in behind the b50, and loaded another .22 pellet,
I looked at him and said..
I JUST DID!
The look on his face was priceless...
-
I feel Daniel, Dave & Tom have the best ones out there by far!
I'm not done just yet, I have a few things left to do to mine, I also have 2 others.
Cost as of today = $950, I forgot to add the JDS parts LOL so about $1200.00 includes ammo as well.
50 yds. 5 Shots under a dime! light wind left to right 3 - 5 mph. Got to love it!
