Top of the curve in quality
When my eyes first had contact with this flawless piece of fire breathing metal, I was to eager to make the connection to the lower part of the dragon . As it stands it only took a few shots to understand that accuracy was not going to be an issue before loading the second mag I was hitting center targets at 100 yards with five inch groups , then on the third mag hitting the same hole . W/ 3 inch groups

9 mm
All the parts of my 9mm were of excellent quality. Everything went together very well. Everything have a nice tight fit and it shoots flawlessly with 200 rounds fired. I recommend this build to anyone wanting to build a 9 mm AR.

The team at Juggernaut are fantastic. I needed help with my JT-9 build and they not only helped but followed afterwards to make my needs were met.
