The recoil isn't as bad as you would think. It is a pretty well designed recoil system. HOWEVER... My unit had a lot of issues with the buffer and feeding problems.
so I am just being a bit cautious. Maybe a few mags worth in prone then I may shoot it standing up. But I dont see me shooting a barrett anytime soon as I dont know anyone who has one and plus I dont know where to go to fondle one either. Maybe some day.
I would compare it's recoil to that of a 12 Ga firing 3in shells.
