NEW Hybrid Muzzle Device (HMD) by Mad Dog Weapon Systems

    Mad Dog Weapon Systems has introduced a new muzzle device which is a combination of a compensator and a flash hider. It is called Hybrid Muzzle Device (HMD).

    The compensator portion features 3 rows of ports – 4 in the middle (12 o’clock) and 7 on each side. The front flash hider portion is a conventional birdcage type design. There is a set screw to clock and fix this muzzle device, but you can also use a crush washer (not included) to install it. The bottom of the compensator is fluted for weight reduction. It also has flat surfaces at the rear to tighten it with a 3/4″ wrench.

    The HMD comes in three different versions designed for .277, .308 and .358 calibers. Obviously, each of them will also be compatible with smaller calibers than one it is designed for. All versions are threaded with a 5/8-24 thread pitch. The HMD is made of stainless steel and has a bead blasted matte finish. It weighs 4.3 oz, has an overall length of 3.245″ and .870″ diameter.

    Here is a comparison of two screenshots from an MDWS video showing the difference between the bare muzzle and their hybrid muzzle device.

    The Hybrid Muzzle Device is available through MDWS’s website at an MSRP of $89.99 (regardless of the caliber). The price also includes the shipping.
