I recently acquired a POF Rogue in 308. It came with a propriatory single chamber brake with two small jet taps at 12 o'clock so finding any effectiveness testing on it is not available. While I think it does a good job of reducing recoil, you still get pushed off target pretty good since the rifle only weighs 6#. I am wondering if upgrading it to a Precision Armaments M4-72 which appears to be at the high end of the scale for recoil reduction. Just trying to figure out if the juice is worth the squeeze.
