About the options:


Choosing between the two most popular calibers for an AR15 isn't always an easy choice. However, it really comes down to what you want to do with it. Out of such a short barrel, the .300BLK will carry more energy, though the 5.56 will move quicker, shoot flatter, and cost you less. For a more in depth look, take a look at our blog post on the most popular AR 15 calibers. 

Muzzle Device
A2 Style Flash Hider or Compact Muzzle Brake? While mostly a matter of looks or preference, some states have outlawed A2 Style Flash Hiders or consider them to be "evil features", contributing toward what may or may not be considered an "assault rifle" under the definition of state law. Be sure to read and understand your local laws. Aside from the legality, there are benefits in looks and performance when choosing a Compact Muzzle Brake. Muzzle brakes, besides looking cool, divert the gasses exiting the barrel in such a way that reduces recoil and muzzle rise, and can improve follow-up shot accuracy. More Questions?
