My Grendel was shooting great, but I just had to put a new Sampson handguard on. In this process I had the barrel viced and was tightening the barrel nut - something gave. My Sabre barrel started screwing out of the extension. Now the timing is off and theres no way I can reset it personally. Im in East Texas does anyone know a gunsmith close to me and/or have any idea what it might cost to have this tightened back on?
