The Super Hogster is available with Tactical QR mount only at this time. As ah929rr mentioned, it has a locking mechanism. From my perspective, it seems more heavy duty in comparison to the Standard Bering QR mount. Also, if a person orders their Hogster 35 from Night Goggles, we have always included the Tactical QR mount at no additional charge. So, from Night Goggles, the 35 and SH have the Tactical and the 25 has the Standard.
