Meet the newest lightweight AR-15 handguard from Aero Precision. The ATLAS S-ONE is designed for lightweight and minimalist AR15 builds. Featuring the unique ATLAS mounting system that is stronger than any other handguard system on the market, Aero Precision brings a new level of quality and accuracy to your AR build. 

Carefully machined from 6061-T6 aluminum, and featuring M-LOK attachment points, S-ONE handguards were designed with custom lightweight builds in mind. Using a patent pending attachment system, S-ONE series handguards offer a monolithic like attachment to your upper, while preserving a slim profile. S-ONE handguards are the quickest, and easiest way to modernize your upper or are a great choice for your lightweight build!


The brand new Aero Taper Lock Attachment System (ATLAS) is both pleasant to look at and highly functional. ATLAS uses two mirrored tapered locking nuts which evenly distribute clamping pressure over a custom designed barrel nut through the use of a turnbuckle screw. This prevents handguard distortion as can happen with many handguards during installation.

All hardware mounting parts are included with the purchase of an S-ONE handguard.
