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.

Excellent Rail, just not for me

by -

Excellent rail with a really cool and different lockup system, that seems pretty bombproof. Fit and finish is excellent as you would expect from an OEM company like Aero. To the reviewer who had issues with the install I have no idea what could have been painful about install, it was breeze with the simple written instructions you can download from Aero. All that being said I am returning because I am not a fan of the missing rail in the middle which is just a personal choice for me. I am glad I tried it for my self. It was going on a lightweight build but again the missing rail on top bugged me
<br>But the rail itself is 5 stars for me across the board, its an excellent lightweight system with a really cool and sturdy lockup system. My issues with it I knew when I bought it, if your like me and want the center rail Id try the R-One which is what im going to do.

Decent rail, dumb install.


Decent rail. Terrible install. Barrel nut has to be timed with aluminum foil rings. And then there's 2 little keepers that screw together with one 2 sided torx screw. Painful.

Amazing rail!

I was pretty blown away by the quality of this rail when I opened the package. I bought it to complete an Aero build (I have their upper and lower in FDE to match), so I know they make quality parts, but holy cow this thing is gorgeous and amazing to handle. It's featherweight, feels super solid, and the ergonomics are perfect for my hand. I have an SLR Helix and also an older Troy rail to compare to, but I would say this stands on its own. Very impressive.
