Alright the base of your gun is good, but it defininatly needs details.This is a decent blocko model, Note how it uses octagons and such.Get rid of the black box at the end and add an octagon or hexagon. Also look at real guns and throw in details on them if you want to, its just really bland.
o_O?Where did that thing come from? Ive never even seen it.
Change the shell br0, it looks like absolute stuff.Change the bullet, it's just a cylinder with a rounded top, last time I checked, bullets had a pointed top and were rather short.
