Hello all, I am looking for input on potential home made heat sink designs for AR barrels.
I am beginning building a upper that will get abused with high round count / heavy firing schedule and have been toying with the idea of barrel heat sinks.
I am aware of the JP enterprise heat sink and am a fan of the design and also aware of its shortcomings; for this upper build accuracy is not paramount, cooling is prioritized.
Unfortunately I am going to be using a heavy chrome lined barrel that has a diameter of larger than .750 near the throat so the JP will not work. So I have turned to custom design.
Does anyone have any ideas that they have dreamed up?
I am going to be using a 1" diameter barrel and up to a 1.8" inside diameter hand guard.
I have considered scraping the whole idea and just using cheap chrome lined barrels that are disposable but figured i would pick the minds of some fellow gun nerds first.
Here's a couple links to potential ideas
^wrap around coil style heat sink (lacks barrel adhesion, and can't find in aluminum)
^ solid heat sink (would need to be lathed out to fit 1" barrel profile, along with some sort of clamping design)
