Introducing the DynaComp D2 (also known as the DynaComp V2 or DynaComp version 2). The DynaComp D2 is a very innovative Patent Pending design based on 4+ years of testing and feed back received on the Original ST DynaComp.


Here are some of the improvements made to the DynaComp D2 design to set it apart from everything else:

The shims/crush washer have been captured in the rear for a much cleaner look. It also prevents your wrench from getting pinched by the crush washer as the crush washer expands. No more little "nicks" on the edges of your crush washer. The D2 will come standard with a stainless steel shim kit for more precise installation but it does work with a crush washer as well.

There are index lines at the 12:00 position and the 6:00 position. It's much easier and much faster to install a muzzle device using the index lines as reference points. The top index line is the quickest reference point and the bottom index line can be used as a second reference point. With these features it will be a lot easier to tell when it's timed/indexed correctly on the barrel.

We have also added an 8 sided hex in the rear for wrench flats. This allows you to get a wrench on it where you feel most comfortable. This feature also allows for much faster and much cleaner instillation of the muzzle device.

The D2 has progressive side ports and the front ports have been eliminated all together. We have found that front ports increased the recoil, it also didn't allow use with frangible ammo. The unique progressive side ports keep the muzzle on target and eliminate the normal up and to the right motion that the AR15 platform is known for. These side ports allow the muzzle to stay exactly where you place it even during sustained fire.

We have integrated two rear venture side ports, these two ports help draw in fresh air to greatly reduce the flash or fireball being thrown from the muzzle. These side ports help keep the powder burn inside of the muzzle device verses being throw out in front of the muzzle device. This greatly reduces the muzzle flash.

We also integrated a front blast baffle or blast cone. The blast baffle serves many purposes. It allows use with frangible ammo, that's a big deal because most LE agencies train with frangible ammo. Now they can train with the same muzzle device they are using on their defensive weapon. The blast cone also rolls back the blast forcing it to exit the side ports verse trying to squeeze out the muzzle hole around the bullet. This greatly increases accuracy. The blast baffle also greatly increases the muzzle devices life span. The D2 will handle sustained full auto fire, no problem. The D2 will out live a CHF barrel.

So what does all this add up to anyways? What will you gain from the D2 over the original DynaComp? This is what you can expect:

  • Nearly 50% less recoil
  • Nearly 40% less flash/fire ball
  • Increased accuracy
  • 3x more durable
  • Much easier and much quicker to stay on target
  • Faster to install and easier to install correctly
  • 100% US Made with a Lifetime Warranty.

Technical Specifications:

The DynaComp D2 body is precision CNC machined from 416R Stainless steel. The blast baffle is precision CNC machined from H13 Tool Steel and held in place using a proprietary method. The D2 also goes through a proprietary heat treating process and many forms of quality control.

The D2 is threaded 1/2"-28 for use on 223/5.56 barrels.

The D2 is predrilled for pinning on 14.5" barrels for 16" OAL. They also include a 3/32 hardened stainless steel dowel pin. The muzzle device must be properly timed/indexed. Then the barrel must be spot drilled to retain the pin. Then the pin gets drove in place and either welded over or fused in place using a Tig welded. The D2 is the correct length to turn a 14.5" barrel into 16" OAL after its been perm attached. It works on 14.7" barrels as well, but obviously your OAL will be slightly longer. The D2 is extremely effective on barrels from 7.5" all the way up to 20"+.

The D2 is available with a Matte Melonite finish or with a Matte Nickel Boron finish.

The D2 is also laser engraved with the Spike's Tactical Spider brand, so that you know what your buying!
