Heavey buffer

[pasttense]

Today I took an aluminum spacer out of my buffer, and replaced it with 7&1/2 shot. maybe it will slow down the cyclic rate and let the rounds enter the bore a little straighter. this afternoon it will be swapped onto a billet receiver trued and bedded.
I will post results when I get a chance.

What problem are you trying to fix? Non of the Pro staff have ever changed out a buffer because of this chambering.
