I have received an MLM/MLE buttplate and, yes they are easily converted for use on the LMC/LEC carbines. The basic profile is identical. The heel extension or tang on the MLM/MLE BP has to be cut off, thinned from the underside and re-shaped to the carbine profile. Once that is done, it is a good fit. The screws should be brass. The steel ones in the photo are temporary until I can find brass replacements.
