i have GA precision AR10 Gen 2 that has a OSS suppressor on it getting a ton of stove pipe malfunctions with several different mags ,does anyone know if there Is there an adjustment on the gas port?
I finally got a benchmark 308 barrel on my Impact 737 action at 75 ft lbs.I checked it with Clymers Go and No go gauges.the problem is the bolt closes with very little if any resistance on the No- Go gauge.Is this normal?Can the rifle be fired?should I send the barrel back?
