The nice thing about MVP's is their ability to take common mags, the .223 takes AR-15 mags...

Apparently they patented their mag catch, which is why ruger and everyone else has had to go a different route. I have half the mind to scrap my rifle and try to bed the bottom metal (plastic)into a kimber hunter in place of the kimbers detachable mag system... just need kimber to make a hunter in .223
