Hammerhead Armament, LLC was founded in 2012 by the husband and wife team of Chris and Dawn Crowell, and is a veteran-owned business that specializes in alternative-bore AR parts and accessories, including barrels, bolts, optics and magazines. We strive to be a "one-stop shop" for alternative AR calibers - .204 Ruger, .450 Bushmaster, 6.8 SPC, .458 SOCOM, and many more. We truly believe in the phrase, "the customer is always right," and will work tirelessly to make sure you're 100% satisfied. We want to become your friend and trusted firearm advisor - not just another online store.
