Aero Precision’s S-ONE line of handguards have been designed with size and weight savings in mind, delivering the perfect handguard for your lightweight build. The Aero Taper Lock Attachment System (ATLAS) is a durable and dependable mounting platform, maintaining a slim profile while providing strength and stability. It features two mirrored, tapered, locking nuts that provide evenly distributed clamping pressure across a custom engineered barrel nut using 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 commonly seen using other mounting systems.

NOTE: ATLAS S-ONE Handguards are not compatible with the Aero Precision M4E1 Enhanced Upper Receiver.

If you’re looking for a light weight rail look no further! This is perfect. Smooth sleek and sexy.

Atlas S-econd to none

Great fit and finish. Super light and easy to install. What more could you need?

The BEST hand guard-...Period

by -

I've had all of them. The only one that comes close is Daniel Defense's 6 screw....But this is the best. As long as you put the barrel nut on and line up the line with your gas tube, you can't tighten on the handguard crooked.
Its light, strong, slim and unobtrusive, but still allows you to put the rails where you want them.

Great buy

I bought an upper with this handguard installed. I liked it so much I bought an additional kit. This is a premium guard , diameter is perfect and Primary Arms is a gold medal vendor!

Aero Atlas-S

This hand guard is probably the most comfortable forend I’ve had on an AR platform. Slim so you can get a good grip on it. Does not snag on anything. Easy to install. Worth every penny… the only thing I can “complain” about is the QD mount closest to the upper receiver, for me is unusable. My bbl profile is to heavy not allowing the QD to lock into place… no deal breaker by any means. Fantastic product I would definitely purchase again.

Light weight and excellent

This rail is both very light and very comfortable in the hands. I highly recommend it for anyone looking to do a lighter build!

I would replace most mid or carbine length quadrails or heatshields with these for comfort and utility.
