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.

I ourchased this handguard on sale. I love it. Very light and smooth. The fitment is excellent. I mounted it on a Colt AR9. I will state that even on AR9s you still need to clock the barrel nut like you are running a gas tube. You need a slit facing at the 12 O'Clock position. It allows the wedge locking tabs on the bottom to seat properly so that they are flush. Excellent product and would buy again.

Nice rail great fitment and finish unusually heavy barrel nut,

by -

Nice lite rail the fit and finish are awesome. However the barrel nut is unusually heavy. I would pay more to have a less heavy barrel nut include. Aero should take a look at maybe selling or providing an aftermarket part for their rail that weighs less.

Even though it did not fit my upper at all, it was a nice built hand-guard. It will NOT fit a billet upper. the wings that fit over the upper to tie it into a seamless looking design do not fit some uppers, especially billet that may have extra material. Wish It would have fit my PSA billet Upper, I like the design and weight.

Nice hand guard

Great looking handguard, nice and lightweight,. Only downside was it will not fit my PSA billet upper receiver,. The lower and tangs that slide onto the upper are blocked by the extra billet material left by palmetto State armory. I can't blame AP its a nice guard.

AAA+++++ Best handguard on the market!

Wow, this is hands down my favorite handguard to date. Very light, and the small diameter keeps your grip tight and your gun under control. Looks awesome too. Fit and finish is perfect, AAA+++
