Image 3 of the original 2.

Added some extra gear to it.

1.) sight (forgot the terms for certain ones, forget if this qualifies as a holo sight or a reddot.)
2.) Suppressor
3.) Magazine that holds +5 more rounds than the previous's magazine.
4.) LED flashlight, i suck at making flashlights.

This was a fun enough 'upgrade' of sorts I think I like it more like this. =P I had to tweak the end of the barrel to look like it could recieve a suppressor. Was a simple stretch and add on a rim and thicken up the rim.

Where the original magazine held 25 to 30 rounds this now adds 5 extra rounds to that. So you get actually 30 rounds or 35 rounds. 5 rounds make all the difference.
