I've heard the M1A is a bit "hard" on the brass as it ejects. Don't know if one can install an ejection port buffer on it, or not.

Anyone M1A owners out there confirm this?

Until I installed the buffer on the HK91, the brass would damn near be bent in half as it was ejected!!!

Any interest in 30-06 brass? I like to chew through those rounds with the M1 Garand!
