I'm going to buy a GII 243 from DPMS really soon. I see they have come out with a 16" version now which is under 7lbs. Help me decide which to go with. Probably 55-70 grain bullets. Will muzzle report be an issue with the 16"? Velocity gain/lost doesn't bother me a bunch, probably 125fps difference between the 2. I'm open to all opinions. Thanks
