A little heavier trigger pull, and/or concentrate on your trigger pull follow through- keeping the trigger pulled back all the way until you are lining up the next shot. If no other cause can be found and your gonna go to SA, I would have them increase the trigger pull weight a little bit.
I ckd the trigger, was good. Went to range aware of double tap. Never happened. Dropped bolt hard on fed pre ammo no slam fire. The good ammo got good groups. Reloads will improve that. I love this rifle. Thank you and the others for help in my new gas operated world.
