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.

  • Best Handguard on the Market

    Posted by RGCGFMT on 23rd Dec 2021

    The ATLAS handguard is, hands down, the best handguard for the AR-15 on the market. Light weight, QD attachment points machined in, the taper lock attachment is extremely solid and doesn't deform the rail when tightened to spec like the more common clamp-style attachments tend to. And to top it all off, they're very competitively-priced. How can you go wrong? I have three ATLAS handguards now, in various lengths, between the S-ONE and R-ONE models. Fit and finish have been impeccable on all. The S-ONE is particularly good for a C-clamp grip for people with smaller hands, and it helps keep your thumb out of your sight line. I can't recommend any handguard for the AR-15 more. If you're looking for a handguard purchase you will not regret, this is the one.

  • Absolutely great handguard

    I absolutely love this handguard. The low weight is phenomenal for the price. I have a 15" guard on an 18" barrel gun. I would definitely buy this one again.

    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.
