Modern rifles, obviously from the Call of Duty series...
First rifle is not an M16, but an Arma-Lite with a hunting scope on top of it.
Second is the infamous AK47, made in good old Russia by Mikhail Kalashnikov.
Third is the G36e, standard issue rifle of the German Army, made by Heckler and Koch.
Fourth is the "Enfield" rifle, or the L85, standard issue rifle of the British Army.
Fifth is the AUG rifle, standard issue rifle of the Austrian Army.
The last, but not least, is the French FAMAS, which stands for "Fusil d'Assaut de la Manufacture d'Armes de Saint-Étienne" or "Assault rifle of the Saint-Étienne weapon factory".
This drawing is my response to Blackknife12, [link]
who miserably draws guns and I almost puked at his crap that he throws around all the time. Learn to draw better, kiddo.
Update 01/30: Okay I'll admit it, I found a lot of mistakes around the guns so this art is real shit ;[ However, I'm sure the next page will be much better than this!!!
