First
"The detachable magazine is often controversially referred to as a clip."

Second
I wasn't able to try out the clips before I bought them as I live in Regina and we are very limited for airsoft dedicated stores.
And what I mean by inconsistent is that only say 1/10 cycles of the gun firing would actually contain a BB. Unless I detached the "magazine" and reattached it.
Thanks for all the input so far.
