The Spike’s Tactical Dynacomp Short is a 5.56 NATO muzzle device designed to reduce recoil impulse and muzzle climb to provide faster follow up shots. The Dynacomp accomplishes this by balancing the direction of the blast along the vertical (upward) and perpendicular planes of the muzzle to lower muzzle rise, while the end of the device restricts forward energy to reduce parallel recoil. The ports on the Spikes Dynacomp Short are ball dimpled for smooth expansion of gases and rapid heat dissipation. The front of the device is 0.25" thick to better handle the abuse of full auto fire. The entire device is Melonite treated to enhance these characteristics and provide a slick black finish. 

Note: The Short model will not bring a 14.5" barrel to legal (non-NFA) length when pinned.

  • Threaded 1/2x28 for 5.56 barrels

As usual awesome shipping time from PA. Good comp for the price, fits my needs.

Spikes Tactical Dynacomp


Awesome muzzle brake !!! Makes controlling the rifle a breeze. And at a great price. Super fast shipping as always.



Compensates for muzzle rise while standing/sitting/prone for quicker second shots. Tends to drift when laying on side but... How often are we in that position? Fit and finish were perfect.

As advertised....


Definitely works very well as a compensator, but not as a flash hider. Great control of the rifle is offered with this compensator.

Spikes Tactical Muzzle Brake


Excellent muzzle brake for reducing muzzle climb. Look and finish matches my RF Melonite barrel also. Primary Arms delivers fast as always...got it the next day!!

Spikes Tactical Shorty Dynacomp (5.56)


Great product, works as advertised!

machined to perfection


High quality manufacturing at a decent price. There is a ton of machining on this sucker. Just tried it out today, it looks awesome and works even better. Good recoil reduction and compensating characteristics, primary delivers again

Sweet comp!


I purchased the comp on a recommendation from a friend. Great product for the price.

Outstanding product and service


if your thinking of purchasing the spikes dynacomp shorty, just do it! You will love it. It's loud, but who cares. Keeps muzzle flat and looks great. If you run a 15" hand guard on a 16" barrel as I do, you will notice your front sight gets blasted by the hot gasses. again who cares, just buy quality parts from primary arms and your GTG. Thanks for your outstanding customer service. Highly recommend shopping at primary arms. Thanks guys and gals!

Fantastic !


Just what I was looking for. A great balance of weight, length, and muzzle compensation. Spikes products are top notch. Primary Arms is always on point with shipping, and customer service, which is why I'd rather order from Texas, than fight all the tactical commandos here at the local gun shops.
