I'm hunting with my son and noticed something that's not right with my new Bison upper. Shot great during break in but while in the stand, I noticed 2 thin washers sliding along the barrel between the gas block and barrel attachment. I have pics but can't seem to upload from here. Can text if needed.
What are these and is it safe to shoot?
Thanks
Jim
