5 of 5 Great upper! July 18, 2020
Reviewer: Brandon Ray from MARTIN, GA United States  
Shoots great as it should! I have ran 168gr and 147gr ammo through it and had 0 problems so far. Will use Picketts Mill on the next build for sure! Don't be a cheap ass and skip the V6G muzzle break either. You won't regret it I promise you!
