Sorry forgot it was a rifle buffer. You can buy heavy rifle buffers. Are you can change out the weights with tungsten weights and then try the experiment I posted above.
What you will see is as you add the weight to the rifle buffer, the felt recoil will smooth out, but the gun will still run just as dirty. Then as the weight reaches a point of to much the gun will start short stroking, undergassed issues. Then if you continue to add weight the problem will worsen till the bolt doesn't unlock anymore.
So you see when again come full circle, the only way to lower the amount of crude getting into the action is to choke back the gas at the gas port.
I have run my grendels with carbine and rifle gas setups with everything from standard gas blocks and heavy buffers and extra power buffer springs.
To the very far opposite with adjustable gas, lowmass bcg and taccom lowmass buffers and reduced power buffer springs.
