Aero Precision offers a premium handguard solution for lightweight MSR builds with its AR-15 ATLAS S-ONE M-LOK free-floating slim line handguards. Made from machined 6061-T6 aluminum, these handguards have been designed to be slim and lightweight without compromising stability and strength expected from Aero Precision handguards.

The AR-15 ATLAS S-ONE slim line handguards use Aero Taper Lock Attachment System (ATLAS). It comes with two mirrored tapered locking nuts, which provide even clamping pressure across a custom barrel nut with turnbuckle screw. This attachment system is both functional and stylish.

These handguards are available in Black and FDE color options and come with a front and rear Picatinny rail, reduced weight by eliminating the center of the top rail, and indexing grooves in the 12 o'clock position for positive grip control. Its outer diameter measures 1.5" while the inner diameter measures 1.3". The rail lengths come in four different sizes - 7"-7.25", 9"-9.19", 12"-12.56", and 15"-14.94".

Note that Aero Precision rail lengths measure from the end of the last Picatinny slot at the muzzle to the point of contact at the receiver. All necessary mounting hardware is included with the AR-15 ATLAS S-ONE slim line handguards.
