Battle Arms Development AR15 Lower Receiver

Yes, it is designed to be fully compatible with TDP/mil-standard AR lower receiver parts, ensuring you can use your preferred trigger groups, safety selectors, and buffer assemblies.

The integrated trigger guard is designed with a streamlined profile that maintains standard clearance, so it should not interfere with most standard gloves or holsters designed for mil-spec receivers.

Instead of using a traditional roll pin that requires a punch and hammer—which risks scratching the finish—this receiver uses a threaded set screw. It allows you to install the bolt catch securely using only a hex key, significantly reducing the risk of marring the receiver.

The flared magwell creates a larger opening that acts as a funnel for your magazines. This design helps guide the magazine into place more reliably, allowing for faster, more intuitive reloads under pressure.

No special tools are required. The captured design keeps the spring and detent contained during assembly, preventing them from flying across the room during installation.

At 6.84 ounces, this receiver is engineered for weight reduction without compromising structural integrity. While exact weight savings depend on the specific forged lower you are comparing it to, it is optimized for builders looking to shave ounces off their total rifle weight.
