Description
Sylvan Arms SA5 Pro AR Folding Stock Adapter, Gen 5, Left Fold, is designed to let an AR-15 build fold to reduce overall length for easier stow and travel. The SA5 Pro sits closer to the AR lower to help reduce length and gaps. Folding direction is set for left-side operation, folding off to the side without the ejection port. CNC-machined from 4140 steel, it weighs 9.4 ounces and uses standard 1-3/16 x 16 threads.
