It appears that Magpul has decided to make a designated 300BLK mag. The popular round has generated enough demand for it I assume. I wondered if anyone would grab the wrong mag and load a 300BLK into a 556 chamber not paying attention and have a bad day. Well the texture of the mag and top lip design I think is different so you don't have to worry so much about it now. With a MSRP of $15.95 will see what they sell for in stores.
