So after a two month wait the results are in. My 6.5 Grendel made its way back out to the range with her primary day optic a Vortex AMG 6 X 24. My reason for sending the rifle back to Larue was because of jamming issues. I created the problem by removing the brake and attaching a direct thread suppressor, an OMEGA. I should have trusted my instincts, don't tinker with the cycling process. Several recommendations were entertained but what I consider a reliable source gave me something to think about. JUST SEND IT BACK, thank you Wig. Turns out Larue does stand by their product. They returned my rifle to me in perfect working condition. I have scrapped the idea of shooting it suppressed. Let it be. I am happy with sub one inch groups at 200m. My PVS-30 and IR illumination device are back in operation. With this happy ending I still view the bolt action rifle as a less problematic firearm. In my experience the AR platform is just to finicky. Kind of like a sexy women with extra baggage.
