Yes I'm quite aware that the BAR is an auto rifle. The nut I was talking about is the nut that attaches the foreend to the rifle (barrel). Unless Browning changed them, yours could be different.checked scope mounting on a new vortex scope! Let it cool between each shot as well as groups. The fore end bolt is also the sling swivel stud. No sling on it! Ill find proper torque and check this bolt. This is a semi automatic rifle you are aware I'm sure. No rounds left in gun! We did find that the cooler the barrel the higher the shots hit!!! Hotter barrel made shots go lower, bassackards from a bolt gun!?! Go figure
Thanks that is exactly what I was just thinking about!! I have observed my shooter buddy seemingly having trouble getting his head steady to make a shotcheek weld is off. I just went through this with my rifle. I would get .5inch groups but the groups would be apart from each other a few inches. I put a cheek riser pad on my stock and it has now gone away.
