5 of 5 6mm Arc 18” February 10, 2023
Reviewer: ChrisN from Az City Az  
I didn’t buy this exact kit however I have the barrel and adjustable gas block. This is my first Odin but have built around 30-40 Ar15s several different calibers and the 6mm Arc is my favorite. The gas system has a screw that covers the adjustment screw. Remove the outer screw and adjust the inner on with one round in the mag shoot the one round and continue this process until the bcg locks back with the empty mag. This is a great product and mine shoots under .5 moa and is still not broken in yet. 500 yards is way too easy with this package. 1000 yards soon. Be patient and this company and caliber will not disappoint you. Buy all the Ar15s you can before the radical left take them from us. Hope this helps.

3 of 5 Did not receive what was ordered. July 6, 2022
Reviewer: Myron McMillen from Helena Montana  
I had my local dealer order a complete 6mm arc upper but what I got was a barrel, forearm, adjustable gas block and gesture.  My dealer had a upper receiver and bcg in stocks so he completed the upper for me rather than reordering the upper.  When I completed the build on my lower and went to the range I found the gas tube would not allow the bcg to extract the fired case. I have taken it back to my dealer and they are going to replace the gas tube as the original one appears to be plugged and the adjustable gas block can't be adjusted to let any pressure into the tube.

Reviewer: Rick Daugherty from Van Buren, AR United States  
The upper came packaged very professionally. I took it to the range and during site in the upper produced one three shot group @ .53" and another @ .64". Very happy with the quality and performance of the upper.
