JTE AR-15 Complete Upper

OUTSTANDING upper receiver and customer service! I have built numerous AR's with different "Name Brand" uppers, but this one performs above and beyond the rest. I will be buying JTE uppers for any future builds.

JTE AR-15 Upper

Ordering process was easy, and I received my new upper in a timely manner. The upper is of the highest quality that I have come to expect from Juggernaut. I have taken it to the range to shoot several times and have had no issues. Super satisfied with the upper.

JTE firearms

Between the wife & I, we own multiple JTE firearms ranging from PCC’s, AR15’s & AR-10’s. I can speak for the both of us that we have enjoyed the customer service as much as the range time. We own 3 private ranges from 10yds to 1480yds and have never been disappointed with our expectations from any caliber platform. Performance is top notch and the custom cerakote applications are just lagniappe…..GOD BLESS
