SA-15 Folding 11.5" Piston Rifle is built on the Shield Arms Folding Lower Receiver (FLR) for compact storage. This patented system allows the firearm 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.

Maritime Operations Features
Special precautions have been taken on our PISTON Series rifles for maritime operations to prevent salt water corrosion, including cerakoting the major components in LR-100 Cerakote.
Cerakote’s unique inorganic LR Black is a low-reflective light-absorbing black coating, designed to absorb visible light spectrum wavelengths. With optical applications in mind, this coating is ideal for military applications. In addition, it meets the Cerakote standard for mechanical durability making it the most durable non-reflective coating on the market.
- Passes ASTM E595-15
- Resistant to Atomic Oxygen
- UV Stable Finish
- Low-reflective and light-absorbing finish, visible spectrum
