Break-in for AR15

I just bought a Fulton Armory match AR15 and I expected it to come with break in instructions but it didn't. Can anyone suggest the best method for break in? It's a Stainless Steel heavy barrel with a 1:7 twist.

Any help would be appreciated.

  Below is a set of steps used to break in stainless match barrels. If your barrel is chrome lined I believe they just recommend you just shoot it and not clean it all that often.
  
  Remove any existing copper fouling from the barrel by using a high-quality copper-removing solvent like Hoppe's No. 9.
  
  Fire 11 single shots, each followed by about 20 strokes of a tight fitting patch bearing bore cleaner. Use a Parker Hale or other wrap-around style jag rather than a slotted jag. From 12 to 30 shots, clean after each 3 shots. From 31 to 50 shots, clean after each 5 shots. Clean thoroughly with a high quality bore cleaner every 10 shots until 100 shots. This time-consuming process will allow the barrel to smooth out without an accumulation of copper fouling in the pores of the steel. The barrel should thereafter be cleaned every 20 rounds for best match accuracy. Accuracy continues to improve for several hundred rounds.

  Thanks Boomer! I'm breaking her in tomorrow morning and I will use this method.
  
  I appreciate the feedback.
