Here is an informative video on AR-15 barrel profiles, length and fluting. There are likely some things in here you didn’t know, as was the case with me. Even if you’re a gunsmith. To some degree this is “gilding the lily.” Most AR-15 barrels are just fine for civilian applications, even in situations of duress like 3-gun competitions. Also, the military has made some bad decisions before on this subject. Imagine that. But there are some bad decisions you can make, and it pays to know what he teaches you.
Nathanial from Faxon Firearms delves into barrel profiles, barrel lengths, fluting and finalize some thoughts on nitride.
Next up Brownells On carbine buffers.
Finally, as a bonus for the avid AR-15 lover like me, this is yet another good video on the operation of the gun in semi-auto and fully automatic mode.
