Query: Fun while it lasts

My 13 year old son had a terrible time trying to assemble this, but now that he's got it together he loves it! It's really fun to play with. Unfortunately the plastic inside (where you pull back the lever) is already 'crackling' after just one day of use so I'm not sure how long this will hold up. It doesn't look like there would be any way to replace it so once that rips or tears you'd have to buy another air gun.
