I know chit chat is to be kept at a minimum, but I want to give this tip out.
I noticed a few guys running Dmags with Phenoms. If that mag release button is getting annoying by being flush with the magwell, I've got a trick that has probably already been told.
Remember that standard magwell that came with your conversion kit for the old style magazines? That mag release button is a perfect fit for the Dmag magwell and is taller so it sticks out a bit. No more dealing with a flush release. And the best part, its probably a free mod for you.
