Aero Precision Inc AR-15 12.7Inch ATLAS S-ONE M-LOK Free Float Handguard

The ATLAS S-ONE is the newest addition to the Aero Precision Handguard lineup. Machined from 6061-T6 aluminum, the S-ONE handguards are engineered with size and weight in mind, providing an ideal handguard for lightweight builds. Aero's proprietary ATLAS attachment system offers a durable and reliable mounting platform, maintaining a slim profile while delivering the strength and stability Aero Precision is known for.

ATLAS System: The Aero Taper Lock Attachment System (ATLAS) features two mirrored tapered locking nuts that evenly distribute clamping pressure across a custom-engineered barrel nut using a turnbuckle screw. A ratcheting detent ensures positive registration during installation, preventing handguard distortion. All necessary mounting hardware is included.
