CA-Legal AR-15 Stock Adapter

Build Examples

Hammerhead is designed to be held with the thumb over the top of the grip. Wrap your hand around it for a secure assertive hold on your rifle.

Here are some examples of Hammerhead rifle builds with parts lists. Hopefully these will spur your imagination and get you started with a build you can call your own.

Photos may not depict a legal configuration in your state. As with all firearms modifications in restricted states, please consult with a competent firearms attorney before modifying your weapon to comply with the law.


"THE SHOULDER THING THAT GOES UP"

This is a very popular build, simply because it is so versatile.  You can build three different configurations and switch between two of them very quickly at the range with just a few turns of an allen wrench.  "The Shoulder Thing That Goes Up" is a famous example of how gun banners are legislating an area they know literally nothing about and every gun owner should know and understand the history of that phrase.
