One of the key benefits of the AR-15 platform is the ability to change calibers by simply swapping a complete upper assembly or by replacing the individual components—the bolt, barrel, upper or lower receiver. Matrix Arms’s .308 Lower Receiver gives you the flexibility to convert your AR-10 or AR-15 to utilize .308 ammunition in a variety of different applications.
Build On Your Own Terms
When building a rifle, you can purchase a fully assembled Upper or choose to assemble one on your own by purchasing and assembling the individual components. If you’re aiming for accuracy, then choosing the right Lower Receiver for your rifle is essential in ensuring you get a stable build that demands precision. The Matrix Arms .308 Lower Receiver is manufactured using American-made Mil-Spec 7075 aluminum forgings, which allows the Lower Receiver to withstand high pressures and extreme heat while also remaining lightweight. The Lower Receiver is also coated in a Hardcoat anodize, with a Matte black finish, which will ensure corrosion resistance and durability.
Matrix Arms .308 Lower Receiver Features:
- Machined from American-made Mil-Spec 7075 Aluminum Alloy Forgings
- Hardcoat anodized/Matte black finish
- Made in the USA
Note: We recommend you combine the Matrix Arms .308 Lower Receiver with one of our patented Upper Receivers.
