Considering where you will be clamping the barrel, the DIY wooden jaw blocks will probably work best unless the barrel diameter is the same as behind the gas block journal on A1/A2 or Hbar.

This reflects my experience as well. Less side blast with the BRT (almost zero), even compared to an A2.
On barrels with a front sight base, I clamp the FSB in a vise using wood or nylon blocks to protect the finish. If there is no FSB, I clamp the barrel between the gas block & muzzle device (if there's room). The advantage is the length of barrel placed under torque is shorter and therefore stiffer. It may not be needed, but it is cheap insurance. However, if the MD is particularly stubborn, the advantage is noticeable.
