LaRue Tactical OBR 762

[SweetZim]

I've got a LaRue Tactical PredatAR 762 with the 16" barrel. Great rifle (obviously). However I've been looking at the OBR 762 rifle as something for a more accurate rifle, basically I was just wondering what kind of differences there are as far as ballistics between the 16", 18" and 20" models. What differences in muzzle velocity and accuracy could I expect to find between the different barrel lengths. Anybody have much in the way of input on this?

You generally get 25 fps per inch of barrel. It will obviously depend on a lot of factors such as powder used, primers, twist rates, etc. The best place to go for precision stuff is SnipersHide, as they have a ton of info about precision rifles and shooting.
