Show off your Disco

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

[Ribbonstone]

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.



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):

3. 2nd barrel band inletted into the stock at the rear (Challenger PCP idea).



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).



Shot count:



Typical accuracy:


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

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/

Argh, jake37 beat me to the disco double photo.
Max flow valve, and enlarged transfer port,
rear velocity adjuster,
Custom trigger,
mellon bolt and probe,
disco double tube, and stock from norm at discos r us,
TKO,
Tasco 6-24 mildot.

~900FPS for over 40 shots. 2000 psi fill
Functional accuracy: less than 1 inch at 25 yards for over 40 shots with 14.3 gr cphp from the tins.
JSB is better.

[AK73]

Here's mine. Fairly stock; TKO LDC, sling mounts, and TKO tuned. I've shot 1/4" groups at 25 and sub 1/2" at 40.

[ezman604]

LOL
If you got it, flaunt it? HeeHee
Got 3 Disco's at the moment. All dressed differently.
.177 dressed in Michael Chavka furniture, BMN breech and home brewed and baffled shroud.



.22 dressed in Steve Corcoran furniture. Breech made by Gene as well as the baffled shroud.



.25 Disco Double in customized Katana stock, MRod trigger group, BMN breech and baffled shroud.



Now I have to decide and buy another Disco for the up and coming Teryx stock setup. LOL

SAFE & Happy Shooting!!!!

Tom

[ezman604]

...and forgot to all...
All of mine have custom power adjusters, valve work, 3 screw trigger work or replaced with MRod group and hammer/spring work.

[Axelr]

Here's mine:

[rloftus]

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...



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:



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.   

[Tomg]

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

[45Bravo]

Ok guys, some of these are no longer discoveries, they are custom works of art..


And makes mine look like a tinker toy..

[Chako]

how much $$$ do you guys have in these??
