Tuning Best upgrades for 2240XL?

My first upgrade would probly be the trigger. Next to changing the whole trigger frame out for a Prod or 1701 frame the SuperSear is the next best thing.

Then the power adjuster to see if you really want the larger volume valve. Then if so, go for it, but combining a power valve with such a short barrel is going to waste allot of Co2. A longer barrel might be a better deal.

You can never go too far with these things and once the addiction takes over the money pit is always near so be careful.
