5 of 5 10.5 300AAC February 7, 2019
Reviewer: Scott Minter from Vancouver, WA  
Building AR's can be addictive.  I had built a 300 blackout rifle a few years ago using a 16" barrel and a polymer lower.  This pistol I used an 80% lower (my first) fitted to this upper.  I was not sure how the gun would run.  I ran just fine.  It also did not take time to sight in.  I've put roughly 120 rounds through it thus far.  No complaints.  Radical is now my go to upper.
