Griffin Armament is a company known for producing firearm components, including low profile AR15 upper receivers and Dual Lok silencers. Founded by two brothers who served as combat veterans in Operation Iraqi Freedom, the company began with a focus on silencers due to the founders’ experiences with hearing loss from military service. Both were Army Sniper qualified and used their background to develop products for shooters. Based in Watertown, Wisconsin, Griffin Armament has expanded its offerings to include upper receivers and other firearm parts.
The low profile AR15 upper receivers from Griffin Armament are designed for use with the AR15 platform. These uppers are forged from 7075-T6 aluminum, a material chosen for its strength and light weight. The receivers undergo a Type 3 hardcoat anodizing process, which provides a durable finish resistant to wear and corrosion. This process ensures the part can withstand regular use and exposure to cleaning solvents. The design is compatible with standard AR15 lower receivers and components, making it a practical option for builders or those upgrading existing rifles.
Griffin Armament’s upper receivers are machined to mil-spec dimensions, ensuring proper fit with other AR15 parts. They feature a flat-top design with a Picatinny rail allowing users to mount optics, sights, or other accessories. The low profile aspect refers to the absence of a fixed front sight and the dimensions of the handguard, giving users flexibility in configuring their rifle. These uppers are intended for reliability and function rather than specialized aesthetics, appealing to those who prioritize performance.
The Dual Lok silencer line is another key offering from Griffin Armament, designed for AR15 rifles and other firearms. Introduced as a modern suppressor system, Dual Lok silencers use a mounting mechanism that combines a tapered interface with a locking collar. This system attaches to compatible muzzle devices, such as brakes or flash hiders. The locking collar provides a secondary retention point with anti-rotation teeth, reducing the chance of the silencer loosening during use. The design avoids wear-prone metal-on-metal contact, aiming for durability and minimal maintenance.
Dual Lok silencers feature a “tubeless” design that reduces weight while maintaining strength. They are made from 718 Inconel and 17-4 stainless steel, materials selected for their resistance to heat and pressure. The silencers incorporate ECO-FLOW baffle technology, which directs gas through the suppressor to reduce backpressure and blowback into the shooter’s face. This feature is particularly relevant for semi-automatic rifles like the AR15, where gas management affects reliability. Models like the Dual Lok 5 and Dual Lok 7 cater to different calibers, with the Dual Lok 5 focused on 5.56mm rounds and the Dual Lok 7 handling up to .300 PRC.
Both the upper receivers and Dual Lok silencers reflect Griffin Armament’s emphasis on functional design informed by real-world experience. The company offers a lifetime warranty on its silencers, indicating confidence in their longevity. These products are manufactured in the United States and are available through various firearm retailers.
