Welcome aboard KEWLSNIPER. It is considered polite if you fill your location in your profile .
Re the 24, from what I can recall. I dont think you will need any special mounts - just buy a good quality set with allen key fastening NOT the slotted screw type or if you can afford a one piece mount.
If your concerned over its power, or lack of it, have it tested at your local friendly gun shop.
If the rifle is in good working order generally the only upgrade I can think of is to p/x it against something more to your liking. I seem to remember the model 24 was imported by Webley a few years ago as the Air Wolf. Strange how companies keep re-using the same names. (e.g. Scorpion )
If Im wrong with any of the above Im sure someone will be along soon to help out.
