AR-15 barrel install question
Im installing a new AR barrel on new Receiver. My book says to torque barrel nut to 30 ft lbs and install red loctite around barrel were it mates with the receiver. Then it says to install anti seize on the threads. Is it necessary to use the red loctite? I've never heard of that on the other installs i've seen on forums and online. It says it's for a stronger mating between the receiver and barrel.
