these are my opinons ok there is no need to do it unless you think this would help you
the smg's (or mac 10 i think) model looks abit weird (at least to me?) i think you should make that slant abit more straight or push it backwards abit. also that top needs to be higher
neat ar15 but i think you should make the magazine's size a bit bigger and push the handle backwards too
sniper's sights look a bit weird, because there is no rear and front sight but its fine if you dont want to change it
you should add blackness inside the barrels and holes
edit:
now went in game and, for the sniper i dont really think scoping is a good mechanic but as stated eariler "these are my opinons ok there is no need to do it unless you think this would help you"
the lmg's firing sound doesnt really sync with the rate of fire
other than all of these the animations and effects are neat
visual drugs stuff
edit2: all melee weapons and the sniper doesnt work on bots
edit3: this addon's revolver conflicts with jack noir's complex pack s&w revolver
