poprocks4s mp5a4. made a lot more realistic than before

 and than pop rocks. so to start off ill name some improvements :
longer laser,  less chance of jamming or exploding, fires less with one trigger pull ( still works best in automater), always working magazine catch ( sometimes the mag doesnt fall out because the push rod gets stuck), and more weight in the bullets. 
they are improved features from my old version. still has the moving stock and similar insides.
so how to use :
i left a mag loaded so you dont have to play around with it . to fire just pull the trigger or press enter, if it goes to far pressing enter then it breaks

 so when theres an empty magazine cock the gun again with the charging handle and pull the magazine catch. once its dropped out put the fresh one in. and pull the trigger. has some stopping power but not an over good trajectory. rate and comment took lots of time to build and perfect

 stil not 100% perfect yet though

 rate and comment please
 edit :
 edit :  when you insert the second magazine press numpad 2
