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.

Great handguard

by -

nice fit and finish, super light, looks great, feels great in hands.
<br>there was no instructions in the box I got. it helps to add a lil aeroshell to the wedges, also timing the little jack screw and getting the wedges spaced properly before tightening it helps it look even. Also start the barrel nut at 35ft/lb because you may need to tighten it more to get it to time up, not for the gas tube but for the wedges. if you have it off and one of the lengthwise groves aren't lined up with your gas tube (or the hole for it if it is AR9) the wedges wont tighten down all the way.
<br>looks great on my new 9mm pistol and I love it.

Anodizing is flawless. The tapered locking nuts and turnbuckle screw make for a solid connection to the barrel nut; online videos by Aero Precision helped. A light coat of oil on the locking nuts help with install. Barrel nut alignment is more for the locking nuts as others also note that the gas tube rides well above the barrel nut.
<br>I used a Superlative Arms .750 clamp-on adjustable gas block for a 6.5 Grendel 11" barrel. I had to slightly bend the gas tube to make sure that it cleared the Atlas-S; no problem to clear an Atlas-R. Next time around I'll try a straight gas tube.
<br>Compared to a similar ALG Defense rail, the Atlas-S is smaller in diameter and makes for a noticeably better c-clamp grip. A QD slot is on each side of the handguard near the barrel nut.
<br>This is an excellent rail and relatively easy to install.
