For comparison:
Swiss K31 w/ empty 6 round mag - 9 lbs 1 oz
M16A4 with empty 30 round mag - 8 lbs even (an FN15 but it's a duplicate of the Colt M16A4 except semi-auto)
Swedish M96 w/ 29" barrel - 8 lbs 13.5 oz
Yugo M24/47 Mauser, fairly close to a M98 - 8 lbs 7 oz.
Montana 1999 X2 .243 w/ Leupold 3-9X40 in Talley Lightweights - 8 lbs 7.5 oz.
Fwiw, the trigger on the Swiss K31 breaks the cleanest of any of the rifles listed here.
This is mine.
It gets loaded with Hornady 150 SP over a middlin' load of IMR4895.
