Sorry if this has been discussed before, I am new to the forums. If so direct me to the thread.
I just watched a cinema of a multi-player game and saw this glitch. The guy would start out from a new spawn with an AK (normal), but when he would aim and fire it would have the M4 closed-circle reticle (glitch). As he held in the fire for an extended shot, the reticle does not expand (glitch). His boosters where glass jaw and treasure bearer.
