Several caliber/thread/finish options in the works, but here's the sample description for the Matte stainless 5/8-24 .308 version we currently offer along with .277 and .358:


Introducing the MDWS Hybrid Muzzle Device (HMD) .358 Matte Stainless 5/8-24.  This is a new product that is not only a compensator but also a flash suppressor.  The 18-port compensator chamber 
has a unique science built into it; it significantly reduces muzzle climb and can be clocked and locked for right or left hand shooters, while the A1 Birdcage style flash suppression chamber provides a substantial reduction in muzzle flash.

The hidden science behind the HMD is the transition between the two chambers.  The compensation chamber's ports provide a mean of escape for the initial exhaust of air in front of the bullet allowing the bullet to travel into the second chamber with less interference.  Meanwhile, the compensation chamber is comprised of 18 total ports, 4 of which are dead-center 12 O'Clock for center-line reference.  As you can see in the photos, flash is considerably reduced compared to no muzzle device.  Please see the below YouTube Video of live fire comparisons that quantify the comparison photograph.

This model is Matte Stainless Steel, is threaded 5/8-24, and is for .358 (or less) caliber rifles.  This model includes the fluting on the 6 O'Clock side of the device.  It is also engraved with the MDWS .358 designation.

The HMD comes tapped and with a brass-tip set-screw to lock it in place, or, you can use a traditional crush washer behind the device or even a combination of both if you so choose (No crush washers included).

The HMD weighs in at an insignificant 4.3 ounces and is 3.245" Long by .870" Wide.  Truly invaluable performance for little added weight and length.

Stay on Target with the HMD.

Price Includes Shipping.

ADJUSTING THE HMD FOR OPTIMAL PERFORMANCE

As you can read and see in the above post, the HMD comes without a crush washer or "timing shims", but instead is equipped with a brass-tipped set screw to lock the unit into place.

Adjusting the position, or timing, of the HMD is critical to achieve the best results. 

For optimum results, the HMD must be tuned for a right, or left, handed shooter.  For a RH shooter, the center row of ports are to the LEFT of the rifleā€™s bore axis (viewing from the butt to muzzle) by 45-15 degrees; for a LH shooter, the center row of ports are to the RIGHT of the bore axis between 15-45 degrees.

In other words - if you are a RIGHT handed shooter, best results come from timing the HMD from about 10:30 (again, from butt to muzzle) to 11:30.  If you shoot mostly unsupported, favor the 10:30 position, if you shoot mostly supported - favor 11:00 to 11:30.  If you are a LEFT handed shooter, your best performance comes from 12:30 to 1:30.  Again - supported shooting favors more vertical timing while LH unsupported favors the 1:30 position.  "Rack guns" - those used by right or left hand shooters randomly, are best timed at 12:00 (i.e., the center row of ports directly at 12:00). 

That is the reasons the HMD comes with a lock screw... so the timing isn't dependent on a crush washer.  I use a single lead shot pellet (#7 or 8) under the set screw to press into the muzzle threads.  This protects the threads and absolutely secures the HHD in place.  It will NOT shoot loose!
