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.

    Awesome handguard. Im pleased. My only issue is that there were no instructions included with kit for install. I figured it out, but it couldve been even quicker! Love the looks of this thing! Nice Aero quality.

    Outstanding fit and finish. Exactly what I wanted for my build.

  • Atlas m-lok 9 inch Handguard

    Posted by David on 7th Jun 2019

    Exactly what I wanted. The 9-in goes just past the gas block. I have a 16" HBAR and I needed to shave off a mm from the bottom of the gas block clamp to get it to fit with no contact. The barrel nut fit the inside of the foreend closely, and allowed slight movement WITHOUT the lock wedges installed. I put a light coat of black paint on the nut and it was a friction fit after that. With the lock wedges installed the foreend does not move. Overall, I'm very happy with the S-one and Wing Tactical.

    Very nice and just what I wanted. My only complaint would only be the wedge pin to fasten, as there were no directions and took a little playing to make sure I installed properly. Also installed an m-lok bipod stud. Nice and solid and looks good.

  • Great handguard.

    I dont know what to say than that I'm impressed all around, the handguard is very light, I wish I would have went longer now knowing how light it is. It feels great in my hands. I feel it's worth every dollar and more. The item arrived fast and in great shape.

  • light weight and built-in anti rotation tap

    Posted by bo tao on 2nd Jan 2019

    AP is in the forefront when it comes to innovation, this handguard is no exception. The built-in anti rotation taps and barrel nut set up provided a solid attachment. I wish they offered more length choices; the 7, 9, and 12, length stop too short for the standard 7.5", 10.5" and 14.5" barrels and too long for the others. Also there is not enough clearance for piston kit or adjustable gas blocks. For solid low profile gas blocks they work just fine.

  • Great hand guard, great site

    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.
