Quoted from DakotaMike:Not sure, haven't seen a mantis protector in person. But the metal protectors / spacers that CGC is using are very thin, much thinner than the plastic spacers that Stern is using.
Here are a couple of pics of the Mantis leg protectors I ordered recently. They look significantly thicker then the ones from the factory. Waiting on my LE
to see if they do the trick. Hopefully by then CGC will have the leg issue straightend out!! ...
