Everyone here that has read my spiel about "ignorant" versus "stupid" knows that I agree using the correct word is important to accurately express thoughts and idea's.
That being said, If the manufacturers themselves use the words interchangeably (at least as far back as the M-1 carbine's "Banana clip" )
It seems to me that the makers should know what their parts are called.
Which renders this whole debate, where otherwise knowledgeable people are arguing over clip or magazine, a ridiculous time waster.
Besides, you're all wrong any way, the box is a clip that inserts into a "well" type magazine. Same idea as the Garand.
