very good info video BricePOI. the 2240 runs around 450- 470 , those numbers refect what barrel length gives you, I just dropped blocked a 2400kt using hpa bottle but with a standared paintball 900psi valve and it moved the stock fps from 557 to about 630 , you will find a lot of these parts can be swapped out, your 2260 is capable of being made hpa for pretty cheap
Thanks BYD, yes, lots of things can be done. I'm doing the valve right now as we speak, and there will be a surprise coming with this one. This could be the last one sold by Crosman, they found a few of them in their warehouse that they didn't know existed from 2021. Bought it in February, then they listed as no longer available. All alterations will be easily reversible.
A steel breech is a must. Buy a spare screw (the tiny ass one under the bolt i bought the flat head instead of hex, glad i did) then a grav mag ( 3d printed magazine available online )
