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 preamble. 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.

  • Great hand guard, great site

    Posted by chris on 22nd Sep 2018

    I ordered this rail in 15” m-lok for a 16” barrel and Aero M4E1 upper. This rail fits perfectly and secures very rigid and sturdy to the upper receiver with no play whatsoever. The rail is very low profile and light, and looks great. There are 4 different tabs extending past the upper which add rigidity and prevent any rotation from occurring, not that the locking mechanism doesn’t take care of that. Due to the low profile and resulting proximity of your hand to the barrel, you’re gonna feel more heat from your barrel than a larger rail if you’re shooting a lot of ammo so some rail covers and such are useful with this rail, although it is certainly bearable without if you’re just plinking.

  • Build an upper around this forend!

    Posted by Gary G on 5th Jul 2018

    I was looking for a way to get away from 4 rails. This forend does just that but allows you to add exactly what you need. I love the fit between the upper and forend, almost molded. The finish matches my Aero upper exactly, the unit is secure and I saved weight. It took me 4 shims to get alignment. Yours may be different. The shims are packaged in a thin plastic bag. Watch that you don't throw them out. I used the 9 inch upper on an 8 inch barrel with the KVA muzzle device. Exactly the fit I wanted.

  • The only hand guard I will run now.

    This hand guard is smooth with no jagged edges...comfortable to hold.
    The barrel nut comes with it's own wrench. Aero says it has to be timed, but it didn't matter on mine...The gas tube fit over the nut in any position.

  • Top Notch Handguard

    Posted by Reece on 5th Jun 2018

    All of my builds are aero precision and for a good reason, the handguard is solid and the rails line right up, installation was a breeze, especially with this locking handguard. Highly recommend for your next build.

  • Great handguards

    Posted by Patrick on 5th Jun 2018

    The handguards came with everything needed for installation, including barrel nut and a hex key for the locking screw. Real easy installation. I put this on an Aero Precision upper with no issue (not the M4E1 upper). The handguards had not a scratch on them and are beautiful. They seem to be pretty durable. I sat on them with all my weight (200 lbs) with no issue. Solid. Wingtactical was easily the best price I could find on the internet and they arrived very quickly (if I remember correctly, it arrived in 3 days after I ordered them). I would definitely recommend this product and this company to anybody. I will be ordering more from this website in the future!

  • Comfortable

    Posted by Jim on 20th Feb 2018

    I have or have used, Seekins, Midwest Ind., Rock River, Monstrum Tactical, this is one of the best. I like not having the complete PIC rail on top, makes it more comfortable if thumb or fingers are over the top. Everyone has different take on connection to receiver, this one is good as any.
    I bought the 12" for a lightweight 300 BO build, waiting on restocking to order 15" for another gun.
