Dan Pistol Cometic Upgrade + Longer Rails

Here are the cosmetic changes:
 

Front Cover: Just make it look a lil bit cooler in my opinion

Front Slider: Increase the length of grip area and delete the holes in the middle of the model

Back Slider: Redesign to look like a more realistic gun and block the view of the insides of the blaster

Back Cover: Deleted the pull tab and wrap around the back slider, also have a space for the dart ram to move
 

Picatinny Rail: Extend it to place the red dot a little bit further back
