Does your AR still look like it belonged in the 20th century? I know, nostalgia has its place, but maybe your rifle shouldn’t be one of them. Keep dads old double barrel in the gun safe, and let your AR move into this century. That means dressing it up and free-floating that barrel out. The most cost-effective, striking, versatile way you can protect your barrel is with an Aero ATLAS R-ONE M-LOK Handguard.

Step Up to The Line

Whether you shoot professionally or just for fun, you’re going to really appreciate the smooth, sleek profile of the Aero R-ONE M-LOK Rail System. Of course, the tried and true Picatinny rail has its place, that would be up on top of your new Aero ATLAS R-ONE M-LOK Handguard. That Pic rail runs the full length, so, you can put your optics and sights anywhere along the way and use all those tough M-LOK slots for the rest of your toys. As you know, M-LOK is the latest and greatest rail system to come down the pike. It has proven to be the strongest of any rail locking system as yet.

The Aero R-ONE M-LOK Handguard Is Tough as A Rhino

The Aero R-ONE M-LOK Rail System is not some space-age polymer. Your new rail is CNC machined out of tough, 6061-T6 aluminum so you certainly won’t have to baby it. Aero Precision has created their Aero Taper Lock Attachment System (ATLAS) to virtually eliminate issues found in older methods of attaching the rail to your receiver. So, check out the Aero ATLAS R-ONE M-LOK Handguard. You will love it, Wing Tactical has it, all you have to do now is get it and get it on.

    My go to handguard which offers excellent quality and price point. Installation and barrel nut timing is very easy with minimal tools.

    Perfect fit . Nice finish. Be aware that a suppressor will not fit its inside diameter.

  • Excellent Handguard

    Posted by RGCGFMT on 26th Sep 2019

    By far the best free-floating M-LOK handguard for the money. Fit and finish are both perfect. The ATLAS method of attachment is simple and superior to many others as it does not "squeeze" the handguard around the barrel nut, preventing potential distortion of the handguard at that location. Slight downside is that rotation is prevented by overlapping the front of the upper receiver, which will limit the types of receivers that this handguard can attach to, but this is a minor gripe. I have two of these now, both S-ONE and R-ONE, and I could not recommend them more, particularly in conjunction with Aero's M4E1 upper receiver.

  • Aero Atlas R-One 15"

    Pretty awesome, I've had the Geissele Rails which are so rock solid and while this isn't as solid it does feel good and much lighter. Unless your looking for a gun to be surviving bombs, I would say this is great!, Easy to install too

  • Atlas Aero Handguard -15"

    Posted by William Becker on 10th Jun 2019

    In my opinion, one of the best handguards out there. I especially like the lock-up system. Looks good, works extremely well (haven't shot it loose yet) and easily removed for whatever reason. These guards are rock solid and mate seamlessly with the p-rail on your mil-spec upper. They do require the use of a lo-profile gas block however (no biggie). And of course, Wing Tactical ships almost before you order so it's a win win.

    Great rail at a great price. Shipping was also super fast

  • Atlas R One

    Posted by Tyler Kelley on 7th Mar 2019

    Liked how this one looked so I decided to give it a go. Originally I was kind of scared the thinner parts of the rail would be super bendable but its actually a very solid build. very appealing finish and feel in hand. I also really like the lockup system. Very impressed with Aero Precision will get more of their stuff. Wing has a great price on these and shipping went smooth. Thanks Wing.

  • Great handguard at a Great Price.

    I've purchased several other handguards for my ARs and have handled many more. I am a fan of other Aero products so I gave the Atlas R-One a go. The price was fantastic and the quality is superb. It feels great in the hand. It might not work with some low profile gas blocks and you might have difficulty attaching accessories around the gas block. This isn't an issue for me and I would highly recommend this handguard to anyone looking for one.

  • Nice handguard, rock solid, needs better instructions

    Posted by Some Old guy in Ohio on 27th Oct 2018

    First off, when you open the box, don't open the foam wrapper, remove the barrel nut and hardware and then discard the wrapper. The shims for timing the barrel nut are taped to one end and very easy to miss. I had to ask Aero Precision support what I was doing wrong when I couldn't torque the nut to spec and line up the groove with the gas tube. I was lucky that I never throw away any packaging until a project is done. Once I added two shims it timed up perfectly at 30ft/lb and the rest of the installation was just as easy as advertised. Finish is nice, once mounted it is dead straight, the barrel is well centered in the tube and it looks like it is going to be very solid and rigid. Further note on installation, time the nut with care, the grooves in the handguard control the location of the handguard, cant the nut and you cant the handguard. I was OCD when I timed my barrel nut and it paid off with a top rail that lined up perfectly with the rail on the upper.
