Here's what I did.
Step 1: spray PAM (non stick cooking spray) down the barrel, make sure you do this from the chamber to keep it out of the action
Step 2: run a bore snake through the bore 4 times
Step 3: crunch up some cheetohs and pack them into the flash hider as tightly as you can
Step 5: fire one round into the dirt but make sure its at least 10 feet away but no more than 12 feet away
Step 6: repeat steps 1-5 until you have used up an entire bottle of PAM and/or a bag of cheetohs
This is the break in procedure I recommend. Redneck, you had better try this on your next AR or you run the risk of ruining it like your last AR. Don't bother telling the gun shop guy about this trick, its super secret and I doubt he has ever even heard of it but it works.
