No, these are not built to the WOF templates. I sat out on the deck one sunny saturday last summer and scaled my own drawing from a bunch of photos. Even so it is close to the WOF measurements. The biggest difference is in the diameter of the barrel and the flash suppressor. Mine are about 20% less than WOF in those areas. The barrel is slightly longer ,also. I believe it looks less bulky that way. The major difference will be in the finish. The MR's look highly polished, these will not be, as befitting a military weapon.
