The anti-rotational barrel nut for our SWITCH™ rail system for the DPMS high profile 308 platform. Having an extra barrel nut allows you to remove our Switch rail from one upper to another in a matter of seconds. Many have found this to be extremely useful. The barrel nut has anti-rotational cutouts and come with shims to time correctly. While most have found that our clamping force on our standard barrel nuts are so tight that this anti-rotational nut isn't needed. You can get this for added protection against rail twist/turn.
