I purchased this as an assembled upper years ago. no markings on barel. Seller claimed this was a YHM assembly. I cannot say one way or the other. I do know it shoots very well.
lightly used heavy barrel would estimate no more than 1000 rounds which i would have put through it.
AR-15 20" Heavy Barrel 5.56 1:9 twist rifel length gas system M4 feed ramps
Shoots really well using a 50 and 55 grain Zmax hand loads. My typical range is 200yards and less. But, I have shot Prarie dogs at 500 yards with it so it is very accurate.
I like it but wanting to get a lighter barrel, as this one weighs 3.5 lbs
