At the heart of the AR10 rifle, is it’s magazines. Without quality magazines, any center fire semi-automatic weapon is just a single shot weapon.
These new manufacture steel constructed mags ensure that your AR10 style rifle will perform when and how it was intended.
Unlike the AR15, AR style rifles chambered in .308 do not quite share the parts interchangeability of the AR-15 chambered in 5.56. You have a couple of manufacturers that build to one platform, and yet others that build to another platform. It is important that you decide which “platform” will be the best option for you.
