10 Ring Sylvan SA5 Pro AR-15 Folding Stock Adapter Gen 5 Left Fold Compatible AR Platforms

The Sylvan Arms SA5 Pro AR-15 Folding Stock Adapter Gen. 5 Left Fold from 10 Ring delivers a compact, travel-ready solution for your AR platform by allowing you to fold your stock and dramatically reduce rifle length for easy stowage without sacrificing reliability. This CNC-machined USA-made folding adapter sits closer to the AR lower to minimize gaps and overall length, turning your rifle into a versatile foldable setup. The folding direction is oriented to the downrange direction on standard builds, with left folds left of the ejection port, and it is available in a left or right fold to match your preferred AR side configuration. Built for broad compatibility, it works with most AR-15 platforms, features standard 1-3/16" x 16 threads, and does not require additional parts when used with standard AR-15 bolt carrier groups. Weighing only 9.4 ounces and crafted from 4140 steel, it includes a 1045 steel bolt extension and castle nut wrench for quick, tool-friendly installation without disassembly. Compatible with .223/5.56, .308, most 9mm, and 300 Blackout ARs, this folding stock adapter lets you screw on, fold, and carry with ease.
