New to building with lots of questions.

Thanks for the info Klem. I think I am going with a Midwest Industries GenII SS series. It is a clamp type handguard that comes with a barrel wrench that will probably involve locking the torque bar in the vise in a vertical position with the barrel pointing up, torque wrench on the supplied barrel wrench. At least thats the way I'm envisioning it. If that does not work I'm thinking I could machine a block to go in the vise to stabilize the supplied wrench, barrel pointing down, and torque with the torque bar from above.
