For me after I installed mine it took out a lot of the sloppiness compared to the factory bolt body and that was my only reason for buying it in the first place. I read a review of it on Midway and the guy said he felt like it reduced his sloppiness by 80% I don't know if I can make that claim, but I will say to me it is a night and day difference over the factory bolt body as far as the sloppiness/smoothness and was well worth the money. The fact that it is spiral fluted and looks cool is just a added bonus......
