There are problems with some free float handguards that can make picking a new one a bit of a challenge. Some forends warp under pressure when they’re mounted and nobody wants to spend good money on something that literally gives under pressure. If you’re ready to buy an M-LOK free-float handguard, Wing Tactical has the one for you. The latest generation of lightweight Aero Precision Handguards features a proprietary mounting system that equalizes pressure to provide a secure installation without warping the handguard. The Aero Precision ATLAS S-One M-LOK Handguard will make your build (if not your life) complete.

How Does the ATLAS System Work?

The Aero Taper Lock Attachment System uses a specialized barrel nut and turnbuckle screw combination to evenly distribute pressure so that the handguard won’t twist or warp. The added security of a ratcheting detent assures you have a secure handguard that looks great.

It Isn’t Just Pretty; It’s Ready to Work

The Aero Precision ATLAS S-One M-LOK Handguard features M-LOK rails for quick attachment of accessories in the field without a lot of preambles. Simple adapters will allow you to refit your Picatinny accessories to the M-LOK rail for the same speed and ease of use you enjoy from native M-LOK components. The front and back end of the ATLAS S-One M-LOK handguard offer sections of Picatinny Rail for accessories you might want to use in those positions.

Advanced Design Provides a Secure, Comfortable Grip

This Aero Precision Handguard included machined ridging across the 12 o’clock surface that provides a little extra grip but doesn’t negatively affect the operator’s comfort. When you equip your rifle with the Aero Precision ATLAS S-One handguard, you’ll get a secure, comfortable M-LOK free float handguard that has all the features you need and great looks too.

    Overall it’s a nice looking mostly functional guard. The measurements for dimension are not quite accurate and if you plan on running an adjustable gas block like I am I tried a few options. Only one that fit was the superlative arms low profile adjustable. I’m not the biggest fan of the was the guard is secured, however it seems to be holding well. Time will tell.

    The handguard is nice feeling and appearance. Sadly i have tried 2 different adjustable gas blocks both with deminsions that say they'll fit (barely) and they dont without force (odin low profile adjustable and JP enterprises adjustable low profile gas block). I'm not sure if anything other than Aeros own low profile adjustable will fit, so just be aware if your plan is to use an adjustable set up.

    I am on my 5th build using this and would use no other. Easy on, easy off. Nice smooth design for comfortable grip.

  • Solid addition

    Everything about this handguard is spot on. Fit, form, and function! It mounts solid with no deformation.

  • Excellent overall!

  • I can’t use it

    Posted by Erik T on 8th Mar 2020

    I love Aero and their quality. I was disappointed that it would not fit on my x-products side charging upper. I guess I needed to pay attention to the fact that this upper does not fit flush to the upper.. it slides past the side of the upper... well it’s supposed to. Now I have extra hand guards for a friend :(

  • Great purchase

    Solid system for the money comes with barrel nut and custom wrench along with all installation hardware fits great and looks great. Will buy again
