Its going to be magazine fed so I don't think loading will be an issue.

BTW i just opened up my Mcmaster 1/4 inch QEV, and it is a diaphram. Its extremely sturdy, held up to multiple 400 PSI shots....

and the penetration i got with .177 BB's was AMAZING. im pretty sure your airsoft gun is going to need "power down"........ lol.

On the ones with flexible pistons, could one perhaps reinforce it?
