Dear Magpul,
Can you tell me what kind of sorcery is required to get these things to snap together? I just purchased six boxes of FDE panels, and I can't get any of them to lock in place. I've tried them on Centurion Arms, LaRue, Daniel Defense, Seekins, and .gov contract P&S rails, as well as some Magpul brand rail sections (polymer & aluminum). I've hit them with my biggest purse, all my friend's purses, and the purse of a random stranger without luck. Seriously, I have tried to squeeze them together with a large slip-joint plier and they won't lock before the plier jaws mangle the panel itself.
I have a bunch of the old non-enhanced panels and they'll attach to everything with ease. This is the first time I've ever had any issue with Magpul stuff. I have fussed with them for about an hour, and I'm rather frustrated and disappointed at this point.
