Popular mods for field target discos

Will you be starting in Hunter division? You will need a scope that can range well and has reticle for hold over points.

I've started with maximum, added regulator, accuracy was great from sticks, but standing was challenge. You most likely will need better fit stock to address balance and fit. You will also need better trigger, because that means better accuracy.

I have Aztec scope too and love it, good choice!
I've mentioned that you would want to get another stock (boyds) and marauder trigger group, but you don't have to at the start. Start shooting matches and you will see.

Do not over look making the rifle fit you. Cut/chop/hack/bondo, custom carve a stock/other.

Esp. it FT it needs to fit.

You have already been to myour local FT club where folks have scopes you can look through , maybe purchase ... right?

A regulator won't do any good unless you modify the valve screws for increased fill pressure. Order a transfer port from crosman CH2009‐026 and spare seal 130‐036. This is the transfer port for a challenger, the opening will measure about .050. Drill it out to about .08" and install it in your rifle. After that you can install a commercially available power adjuster to tune or start clipping you hammer spring one coil at a time and shooting shot strings over a chrony until you get a good usable bell curve. Your stock transfer port is .125 and too big for the power you need. I had a regulator in my rifle and had it tuned for 12 ft lbs with a shot count of over 60 with 2500 fill. Then the reg went out and I threw it in the back of the closet and went to shooting springers instead. At 17 or 18 ft lbs you should be able to get 40 shots or so. There is a brass trigger kit available that will lighten the pull quite a bit.

Another option to help accuracy and shot count is to make or purchase an SSG for your disco. I won't post any links to other forums, but if you do a google search " Benjamin Discovery SSG " you can study up on the subject.

I made one for my sons .22 cal. disco and the results were fantastic.

Here is a 20 shot string when purchased new. This is with the recommended 2000psi fill. No modifications to rifle. It was pretty sad.



Below is a 30 shot string after adding an RVA (power adjuster) from Ebay. 2100psi fill. Better, but not great.



Fashioned an SSG using the RVA I bought off Ebay and a spring from Menards. Filled to 1900psi. A 40 shot string resulted in over 18fpe and a 20ES. Effeciency looks pretty good also. 



If filled to 2050psi a decent string of 50 shots was achieved. Effeciency dropped a bit and the ES jumped to 42. 



On a 2200psi fill(which is max I will go with the factory valve screws) the rifle eked out 60 shots at 18.23 fpe with ES of 58. 



Total cost of the SSG mod is less than 20.00USD
Another benefit is the rifle is much quieter.

You will also need a plan to deal with the wandering point of impact. If you use double barrel bands, the poi will change with the pressure in the tank. If you free float it, the thin Crosman barrel will be pointing a new direction every time you take it out of the case.
