Hello everyone, just wondering on the take down pins on the apc 9k. All the videos I’ve seen your able to take upper apart from lower, mine on the other hand isn’t able to. The take down pin in the front is fixed in place but the rear one opens, so for cleaning it you remove stock and basically it swings open upper still attached. So I’m guessing apc 9k like mine doesn’t take glock lowers which I don’t care for but I was under the assumption upper and lower would detach from each other?
