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.
Secure wrap-around hold, with your thumb over the top.
Hammerhead™ replaces the pistol grip on your AR-15. When configured properly it can help you keep your rifle legal in jurisdictions where the pistol grip is restricted. In operation it feels very much like holding a wooden rifle. Manufactured from a very strong engineered polymer material, it'll survive the most challenging missions. Hammerhead™ carries a 90-day no questions asked no hassle guarantee, and a five year warranty against defects in materials and manufacturing.

Hammerhead™ is engineered and tested to work with mil-spec forged AR-15 lower receivers. While the product may work with billet lowers, these lowers often have wide variances in dimensioning that could impact the fit of this product. It may be necessary to modify the product to fit on any given billet lower. Modifications to the product void the warranty.
CALIFORNIA: California Department of Justice Bureau of Firearms attests that Hammerhead™ is not a pistol grip and therefore legal when used on a detachable magazine semiautomatic centerfire rifle with none of the features listed in CA PC 30515(a)(1)(A-F).1

attached to the rear threads of this product (Type I or Type II config)
and no other NY-SAFE prohibited features would be considered a sporting rifle
