My Cyma Airsoft Gun

my cyma airsoft gun doesnt work and im returning it for a new one. does it matter if i painted the mag of my airsoft gun from orange to black. the picture of the gun on the box has a black mag so will it matter.

thats iffy........ usually when returning things, the store wants it returned as is or as it was sold. usually any modifications or anything else will void your return policy

What's wrong with it exactly? Why did you paint the mag if the gun was broken? The store might use that as an excuse not to allow you to return and exchange it.
