Took a few tries, works now July 26, 2017
Reviewer: Craig from Beaverton , OR United States  
Had a few issues initially, but after warranty work and different bolt parts, its working now.  It didn't like my RRA bolt with Tubbs extractor/ejector spring upgrade.  It works with a stock PSA bolt/m16 carrier and H buffer.

Above and Beyond Service May 3, 2017
Reviewer: don arndt from west bloomfield, MI United States  
Just wanted to stop by and say thanks to James and everyone there. I had ordered this upper to use with my RFA 300 Blk Out to be able to practice with cheaper ammo. I made an error in ordering and everyone was great. No hassle, just made it right for me. My fault they did not have to. The quality and look can only be described as unbelievable. Then add the price point and cant be beat. One thing that you don't get in sub $1000 guns is a quality tight quality fit. Well with Radical you do. Everyone at the range comments on how well it fits together. No rattles! This upper snapped right in and just as tight as the original.

Excellent quality and finish, super fast shipping. I was actually very surprised at the quality upon opening the well packed box considering the low cost. Highly recommended!
