The Sylvan Arms SA5P-R SA5 Folding Stock Adaptor 4140 Steel Black is a compact, right-hand folding adapter engineered for AR-pattern rifles that need easier storage and transport without sacrificing reliability. CNC-machined from robust 4140 steel and weighing only 9.4 ounces, this Gen 5 adapter threads directly onto standard 1-3/16 x 16 buffer tubes and integrates a hardened buffer pin and 1045 steel bolt extension for long-term durability.

This folding stock adaptor is ideal for shooters who want to shorten their AR-15, AR-9, or compatible .223/5.56, .308, 300 Blackout, and most 9mm builds for range use, training, or discreet carry in tight spaces such as vehicles or compact cases. Adjustable hinge tension, two QD attachment points, and an enhanced locking mechanism help maintain a solid feel when deployed, while installation can be completed in minutes with the included tools. The SA5P-R reflects Sylvan Arms’ reputation for thoughtful engineering and practical innovation in modern rifle accessories.
