USGreat Quality as always from NBS!!
Barrel fit my mil spec upper nice & tight & after cleaning showed strong bright rifling throughout! Currently shooting moa @ 100 yards unsuppressed w/ Barnes vortex supersonic ammo. Haven’t tried her yet w/ a suppressor but will be able to soon. I’m sure the groups will tighten even more!

Update Review
This is an update to the review that I posted last May 2020. After about 800 rounds now, this barrel is way more that just awesome. I have settled on 125 gr ammo and this thing just spits'um out. Don't get me wrong it will eat anything, but I just prefer supersonic. With a red dot, I can hit 15 clays with 15 shots at 100 yards what I'll call "off-hand", meaning cheek on brace and not shouldered. So just buy it. As for AR15 Discounts, they are at the top of the list because of their extraordinary customer service and they will pull out all the stops to make sure that their customers are happy. I am a permanent customer and you will be too.
