AR-15 Deep Clean Part 1 - Disassembly and Barrel Cleaning

In this video, I strip down my Huldra 5.56
I have shot over 2k rounds through it without a thorough cleaning and it is time to get it done. It did require some elbow grease and some patience.
Look and see how bad it was!

It can take a lot of cleaning after that amount of rounds . It looks pretty good now .

I am happy with it. That last bit of carbon got me though.

Gas port doesn't look like 2k rounds. You shooting light loads?

[@mattsreloadingbench]

Half of em factory loads, but last half were handloads with win748 powder

I’ve heard that you want some copper in there for accuracy? Does it even out the microscopic highs and lows inside the barrel ? Thought I heard that from competition shooters?

It totally depends on the application of that particular rifle. If you are doing benchreat or f class, you want that barrel squeaky clean. That is where you get the best precision. If you leave your barrel dirty, you can find more consistency with high volume shooting.
I have reached a mile target doing both methods. With a really clean barrel, my groups are much tighter at that distance. But once I hit about 50 rounds, it drops off.
With the dirty barrel, if set to shoot this way, I can hit the target more consistently but I my groups are much larger. I might not hit the target every single shot, but I am in the ballpark. Having done practice with the dirty barrel, you don't have a drop off point that is quite as noticeable.
Like I said, it all depends on the application and the results for which you want to achieve.
