I like the barrel, very well made, but honestly I haven't shot it a ton. It appears to be reasonably accurate, but I have been tinkering with hand loads in it, and haven't found anything that it really likes yet.
Looks great. I think I am going to make the leap into the suppressor world too I can't decide on a .300 blackout or 6.8 to put it on though. Getting ready for another build, but I can't do both right now.
