Well first thing is don't use a thin profile barrel and the for me I like to give bout 2 minutes between each shot and bout 10 minutes break between each 5 round mag.
I also take a small desk top fan to the range and keep it blowing on the rifle at all times.
I speak from first hand knowledge on the thin profile have two 18 inch light weight jp barrels and if I rip throw a 5 round make quickly is hot and will effect groups on the next mag.
Hope this helps sir.
Forgot to add use a short handguard with lots of openings so the barrel can breath easyer.
