AR-15 rifles built on the Shield Arms NO ADAPTER Folding Lower Receiver (FLR). This patented system allows the AR-15 to fold and does not use an adapter. Our system is lighter, stronger, and shorter in overall length versus popular folding adapters. Additionally, our system does not modify the carrier.
Our Piston Series rifles utilize a short stroke piston system instead of a standard direct impingement (DI) system for cleaner operation.
