Monopod was off for the groups. The rear was bagged and the bipod set low. Shots were from prone.
I hear what you are saying about the buffer, but with a couple thosand rounds on my first grendel, I have no issue. But its easy enough to slap a rifle buffer in there and see how it goes. Ill do that for my next trip out.
The scope bridging issue is trickier. Im taking off the prs so lop adjustment will not be so easy.
So if my handguard is trying to flex independant of the reciever, that means I am putting stress on the front ring Picatinny clamp. If I moved the ring further forward, completely to the handguard, the flex would probably move to the scope (bad). The rings I am using are pretty beefy, but I don't understand how much force is in play here (anyone want to run an FEA for me ;-) and if the ring can take the stress indefinitely or fail quickly. Guess I will find out. If my scope loosens up, I will report back.
