While I'd never try and do it myself, converting the AGA to .50 has its merits... To be honest I don't think it would be that hard, as 1/2" ID tubing is way more common than .68 compatible tubing, and since there are less obstructions/openings between the valve and the ball on an AGA it will most likely get better velocity and efficiency with .50 cal.
The only problem with grabbing the whole 357 off amazon is the seller might not ship to your particular state. I know most will not ship pellet guns to NJ as I believe they are somehow illegal here. Not sure on the particulars of other states/regions.
But of course I'm going to be the idiot who tries to go the opposite way on this one and convert it to .68 instead.
