There was a fellow that used to post here regularly who builds the WCI muzzle brake that AA sells. He and BA I believe(correct me if I am wrong) found the ideal buffer weight for the Grendel to be 152 grams. That is very close to the T3 weight of 154 grams. I had a light buffer in my Grendel and have an adjustable gas block so was able to balance the light buffer. I bought a camera that allows 1000 frames per second movies, so naturally I shot a close-up of the action cycling. I found that the bolt would bounce about 1/4" to 1/3". I got a H3G buffer from WCI and it practically eliminated the bolt bounce.
