No, I just allowed the round to come from the mag, its a Pmag. My neighbor has a scale, we just weighed the buffer, its 2.985 OZ. Just for kicks we weighed the buffer from the M&P 223. It weighed the exact same (2.985), however the spring was shorter in the 223. so this leads me to thinking I either need a heavier buffer (5.4 OZ) or a lighter shorter spring. My 308 spring is 13 inches, and I see the standard 308 spring is 12 3/4...
I can't imagine, S&W put the incorrect buffer in this?
