The merlin hole is lacking proper protection, just a technicality, but it is lacking the Pinbits one and possibly the mantis as well, hard to see that one..I installed 10 Pinbits plastic protectors and Pinbits merlin hole protector, 6 cliffys and 4 mantis on my MMR. I agree lots of labor, but not sure you can recoup that. About $250 in protectors including inefficient shipping.
