.308 / 7.62x51mm - With tooth modification required by user
Couplers sold as Scratch & Dent are due to the overall tight fit of the coupler itself. Our couplers use a series of teeth on both sides of the coupler to hold the coupler tight to the magazine body and during pre-production runs we may get units back from the molder that are just to tight to fit to the magazine body without modifications. Couplers sold as Scratch & dent will need to be modified by filing down the teeth of the coupler. They can and will fit with modification.
