Mine's a 18 inch bull barrel with a quad rail handguard... The barrel is turned down a little under the handguard to save some weight. I'll have to get some photos, I think it is about 13lbs empty.
Shoots amazing though, had a sub-minute 10 shot group in a precision scoped rifle class. We did some cool trick shots for fun on a roughly 1" price tag taped to the bottom of your target fluttering around in the wind.
