If you take the muzzle break off they do. Have you ever shot one? I did kind of frequently in my past career and my 12g with pheasant loads kicks more. My M700 in .270 kicks way more than the Barrett did. The rifle however is so goddamn loud it's the one gun I've been around that still made me flinch when it went off no matter what. The other bizarre thing is that there's so much heat given off by the barrel after shooting 30+ rounds through it that your scope view is distorted by the heat coming off the fluting. :assaultriBarret 50 cal has a lot of kick.
History Channel has some good stuff on
