Every one of mine has a heavy buffer, I have heard the same thing repeatedly from fellow shooters/lease members until they shoot my rifles. from 243 up to 358 Winchester, they are a dream to shoot and they don't beat up brass.
I chased this with one rifle until I was ready to part it out, read an article by Slash on ARF.com, ordered his buffer kit, no other changes and the rifle hasn't missed a beat since I installed it.
