The ATLAS R-ONE is the newest addition to the Aero Precision Handguard lineup. Machined from 6061-T6 Aluminum, the R-ONE line of handguards are designed with size and weight in mind, providing the perfect handguard for your lightweight build. Our proprietary ATLAS attachment system is a durable and dependable mounting platform, maintaining a slim profile while still providing the strength and stability customers have grown to love from Aero Precision handguards.The new Aero Taper Lock Attachment System (ATLAS) is both functional and aesthetically pleasing. It features 2 mirrored tapered locking nuts that provide evenly distributed clamping pressure across a custom engineered barrel nut with use of a turnbuckle screw. A ratcheting detent further secures the design while providing positive registration during installation. By design, the even pressure of the ATLAS system avoids distortion of the handguard often seen with current applications during installation.

The Delta 556 was designed as an affordable device that embodies our passion for performance. The Delta 556 maintains great muzzle control characteristics through the large linear ports. This also gives it spectacular flash suppressing characteristics.

The Delta 556 contains no chambers so gas is expelled more forward which reduces the concussion to the shooter although recoil mitigation will feel similar to that of an A2 birdcage. This is a great all around device for tactical, competition or recreational shooters at a very affordable price.
