icant fir my hopper in my gun

[martix_agent]

what hopper do you have? is it too big or small? what marker and feedneck do you have?

[Dark.angel]

Try sanding down the feedneck of your hopper, if that doesn't work I guess buy a new feedneck. This is also the wrong thread bro, the hopper thread is where this goes.
