I have a TKO LDC, three screw mod (but no new trigger), polished leade, recrowned, polished trigger parts, clipped factory spring w/ power adjuster (but could use a better looking screw and purpose-specific spring guide).
I just sold my first springer (*tear*) for $50...so that's what I have to spend. Here is my list, would you add/replace anything:
Extended bolt probe ($12 from Mellon Air)
2nd Barrel band ($7)
Debounce Device (could make one for $1 from Lowe's)
Brass Trigger ($22)
Power Adjuster ($25 from Discos R Us)
Or I could put that money toward a Chrony ($100+)
Thoughts...?

Function trumps fashion.
I vote save it and commit to add $5 or $10 per week.
In a month you might have different desires and better supporting funds.

Do the Disco's benefit from a longer bolt probe? I thought they already had a longer probe than most of the other Crosman/Benji guns. $50 is a good chunk of a chrony! I got one on sale in December for somewhere around $65 I think. Keep your eye on the bargain gate would be my advice. Especially for a CO2 or HPA gun a chrony seems like a really good investment.

All good starts. I would go for the Chrony, first. That way you can tune what you got. The Debounce Device is a waste IMO. I never have any problems with hammer bounce and my Disco is set up to shoot hard (40fpe), and others on this fourm have Discos that are just beasts. 2nd barrel band will be good. I use a stock bolt with no issues. The Mellonaire RVA (pwr adj.) is nice. I have one and worth the cash. You can always buy more hammer springs to experiment with. I have very heavy springs, stock springs, even 13XX springs. I use them in the lengths they come in and cut some down to experiment with.
Word to the wise, and tri-5-ron will agree---gets real expensive, real fast.
Welcome to our hobby, passion, addiction, 2nd spouse, mental release, etc.

Save for the Chrony. :D Then you can determine which other mods will do the most good. ;D
-
Not getting stuff is not as much fun, but I'd save a little more and get a Chronograph. Won't need a fancy one, just a basic version and a pen/paper.

chrony or m-rod trigger group
peace

Making changes to your gun aren't advantageous, unless you can see if they are an actual improvement.

is that extend? it looks longer than oem.
-
If money is tight you can make a power adjustor for a few dollars...and save for a chronny. I got parts from McMaster-Carr (knurled bolt, screw, made spring guide) but You can do even cheaper if you want.
-

Yeah it's longer, or do like mooseslayer said, just make one. You will need a #10-32x1" socket cap screw for the adjuster and a #8-32x3/4" socket cap screw for the spring guide. I would also polish and lube the hammer and the part of the tube where it slides. I use non detergent motor oil. Silicone grease is to thick.

The extended bolt probes *do* help, especially when the probe is turned to a diameter of .060".
I always make sure my probe seats the pellet or slug right at the forward edge of the transfer port hole in the barrel.
If you have your barreled breech off the gun you can close the bolt, mark the probe at the forward edge of the barrels transfer port hole then add the skirt depth to that mark and you have a perfect probe length. A JSB Kings skirt in .25 caliber is roughly .140" deep.
The probe length will be shorter in .22 or .177 as the transfer ports are smaller in diameter.
My .25 caliber probes using a 3/16" transfer port are .250" long (coincidence) x .060" in diameter.
Slugs will seat .140" deeper than a pellet (again, in .25 caliber) so your leade may need some work too so it can be chambered properly.
The advantage to doing this is twofold: accuracy & power.
By having the pellet *just* forward of the transfer port all of your air gets behind the pellet without any waste (power) and the pressure will not deform the bottom edge of the skirt (accuracy).
The other side of this is the bolt will not leave as much room in the loading port due to the longer probe.
I remove about 1/8" (at the most!) from the rear of the bolt to give that much more on the loading port side. Remove too much and there's not enough bolt to push the hammer pin back far enough to cock the gun...its a balancing act.
If you're shooting a .22 caliber its not as bad since the pellets are shorter in length anyway.
This is why I've gone to side cockers so I don't need the hammer pin/bolt to cock the gun. I mill the bolt handle slot longer and that allows me to load a slug up to .650" long since the bolt recesses fully into the breech when opened.
Long answer to a simple question but at least you know *why* you eventually want an extended probe bolt...just be aware of the other factors involved.
After saying all this I am with the other guys - you will benefit the most from a chronograph.

Agreed. Chronograph. you already have a pretty sweet setup from what it sounds.

I bought a 10 year old chrony that had just been sitting for $25. It works good. 8) 8)

-1 for delayed gratification...haha
Thanks for the input. I like tinkering, but you all are right, no point tinkering if you can't measure it...

CHRONY !!!!!

The trigger upgrade is real improvement. The plastic trigger has such a vague feel that its very hard to determine when its going to fire. When I installed my trigger (brass) my groups immediately tightened up.
I would get the trigger and save the rest for a chrony. The hammer spring mod will be pointless without the chrony.
-
Be patient and wait for a chrony. They are always up for cheap here and on yellow.

Either get a chrony, or more pellets, you can never have enough pellets. :)

True...so very true.

I just received my (really heavy) package from PA with enough pellets to make my wife mad...so more pellets would be...well...bad for my marriage...

I just did the same thing $170 on pellets. Easier to ask for forgiveness than permission. That is what I did when I bought a brand new Harley.

You should have seen the smile on my face when I pulled in the driveway, and my daughter fell in love with it and wanted a ride right then. :)

I can tell this forum is going to get me in trouble with my half! But man, I can't imagine trying to break into this hobby/obsession without this forum.

Well I just got a Chrony for $75 bucks, which was nice because CraigsList got me another $50...
So NOW I'm thinking brass trigger with the remaining $25.

I took my advice and got 14 tins of JSB 8.44 pellets & 4 tins of H&N FTT 14.66 5.66 head. Granted I spent a little bit more than $50. LOL

Buy a marauder and a chrony. Learn to love Ramen :)

What chrony did you end up finding? I've been dying to set mine up, but at 4 degrees out I can wait.

Just went on sale for $70...

Its says to use the app from a phone can it be hooked up to either a tablet or laptop?
Any one here on GTA used them?Thoughts?
Considering getting one...
Thanks for the link!

Nice, that's the one I got. But havent set it up like I said. There is a member on here that had gotten one and posted about it, which is what turned me on to it. Same software usually runs both, so as long as you were able to load the app for it you would be fine.

Got the app loaded on my iPad and Android phone. Worked well.
The chrony gave me a few errors, but I was shooting with blowing snow all around me...
Once I moved to where I was shielded from the wind, the errors calmed way down. A few here and there, but not when shooting, only between shots. I'm guessing a snow flake passed through.
-
Well since you already picked up the Chrony that was going to be my first recommendation, as it is a needed piece to tune these guns. I have used 22 lr shell casings for different spring guides in the past. Just double checked, and it did fit in the hammer spring. I can drop you one off for free when we meet up. Oh, and the Mellon PA's are very nice, as you can change the hammer spring without removing the adjuster from the gun, just the adjuster screw.

Thanks Casey,
I found a perfectly sized pop rivet for the spring guide, so I thing I'm good there. But I will look into the Mellon PA. After one day of shooting over the chrony, I can see how changing spring without disassembling is a nice feature.
-
Well, I sold another item on Craigslist and was able to get everything mentioned in this post.
Chrony
TKO LDC
Power Adjuster
Extended bolt probe
2nd Barrel band
Brass Trigger
Three screw trigger mod (Happy with it, so thinking no need for mrod trigger)
Polished leade and lapped barrel
So I'm sort of sitting here thinking, "What's next for my Disco?" Add onto this that squirrels are now extinct from my neighborhood, I'm getting a little bored...
Is it time to get another gun and start the tinkering all over again?
-
You might call your local game warden and see if he knows of any farms/groves that are looking for someone to shoot squirrels, birds, rabbits, ground squirrels, etc. Those guys work a ton and may not have time to shoot their own pests
