Rattling charging handles...lol.
A whiney complaint from those that don't have a clue. Only the latch rattles, and that's entirely due to the way it's constructed.
G charging handles have the latch as a separate piece that has a curved tang which rides in a slot in the left side "ear". The relative geometry between the tang and the slot changes as they move, and can't be made to too close a fit, or they would bind.
All of these, from last year through to new, as well as all of my unpictured CH from years ago, rattle at the latch when not installed in their respective rifles.
I've seen a bunch of people on FB comparing it to the Radian. The Radian has the latch as an integral part of the left "ear", so it is not a separate piece which has to have room to move within the "ear".
Radian makes a great charging handle. So does Geissele. They are designed to different principles of mechanical action to do the same task. But the small rattling of the Geissele latch is a really foolish thing to bitch about, and even more foolish to claim is something that only just came up on the newly made ones.
