Great and versitile mount - Magnetospeed Large Brake Adapter For V3 Chronograph

This mount performed flawless on both an Armalite AR50 and Barrett M99 50 BMG rifles with large brakes. I have also found that it is much easier to use on other guns with smaller barrels as it is easier to set up than the standard strap on mount that comes standard with the Magnetospeed. I did not see any POI shift while shooting with the is mount.
