i have been looking at adapting the A5 hopper... but i thought i would ask people before i went mad and started breaking my A5 loader
Don't do it!
That was a still from the b movie horror 'paintball', and is a fake item. They had various standard and cyclone hoppers stuck to the wrong guns with masking tape
For an a5 low profile hopper I'd assume you have the x7 low profile, as the true a5 hopper is fat and chunky
To make the wide feedneck go down to a standard feed would mean some form of funnel and would defeat the object of low profile
If you want reasonably normal size but low profile then self mod option you could have is to take a standard hopper and shave away at the centre
All that being said, I believe that i have seen photos of a mystery standard feedneck version of the x7 low profile - for the tippmann 98. Whether any realy got made I don't know
