About the options:

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. Read our blog post on muzzle brakes for more info.
**Please note that we recommend buying the AERO Precision Extended Mag Catch Button for .308 as it is not included in the kit. The button is a drop in replacement for the standard lower receiver magazine catch button. This extended button is longer, allowing it to protrude the proper distance when used with our lower.
