Spike's Tactical Dynacomp D2 5.56 Melonite


The Spike's Tactical Dynacomp D2 (or Version 2) is the product of 4+ years of what Spike's Tactical has learned about the original Dynacomps great performance. Spike's took everything that was learned over the years and all the feed back about the original DynaComp and applied it to a brand new design which is now known as the DynaComp D2.

 The multiple improvements include:

  • The shims/crush washer have been captured in the rear for a much cleaner look and also prevents your wrench from getting pinched by the crush washer as the crush washer expands. 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.
  • Index lines at the 12:00 position and the 6:00 position making installation much easier and faster by 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. These make installation a lot easier to tell when it's timed/indexed correctly on the barrel.
  • Spike's 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 Dynacomp D2 has progressive side ports and the front ports have been removed all together. It was found that front ports increased the recoil and didn't allow use of frangible ammo. The unique progressive side ports keep the muzzle on target and eliminate the normal up and to the right motion that the AR-15 platform is known for even during sustained fire.
  • Two new rear venture side ports were added to help draw in fresh air to greatly reduce the flash or fireball from the muzzle. The side ports help keep the powder burn inside of the muzzle device verses shooting out in front of the muzzle device. This has greatly reduced the muzzle flash.
  • Spike's integrated a front blast baffle or blast cone. Amoung the many purposes of the blast baffle are it allows the use of frangible ammo. Most LE agencies train with frangible ammo. Now they can train with the same muzzle device they are using on their carry weapon and you should always train how you fight. The blast baffle also rolls back the blast forcing it to exit the side ports verse trying to squeeze out the muzzle hole around the bullet which greatly increases accuracy. The blast baffle also increases the muzzle devices life span. The D2 will handle sustained full auto fire and will out live a CHF barrel!

This is what will you gain from the D2 over the original DynaComp:
  • 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
  • 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. Also includes 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 weld. The D2 is the correct length to turn a 14.5" barrel into 16" OAL after its been permanently attached. It works on 14.7" barrels as well. 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.
