Aero Precision AR15 Quantum M-LOK Handguard/ Barrel Nut Not Included

Price Save Up to 20% from $84.99 to $72.24

Your M4E1 upper receiver isn't complete without the Aero Precision AR15 Quantum M-LOK Handguard. When you upgrade your rifle with these AR Handguards & Forends by Aero Precision, you gain 8 mounting surfaces for M-LOK accessories. That means more room for your customization needs such as lasers, optics or weapon lights. Another great feature of the AR 15 Quantum Free Float Handguard is that it boosts accuracy when resting the rifle on an unconventional surface. The handguard eliminates any direct point of contact between the barrel and the surface it's resting on, making your shots much more precise. Plus, this product provides better cooling for your barrel, which is especially useful if you have a long session at the range. You'll love the advantages of enhancing your firearm with the Aero Precision Tactical AR15 M-LOK Handguard. Please note that this handguard is specific to the AR15/M4E1 platform and IS NOT compatible with the M5 .308/M5E1 platform. Also, polymer front Magpul MBUS sights may require modification to install this product. If you are attaching this handguard to a standard threaded upper receiver, then you will need to purchase a barrel nut that is not included with this item. However, if you're using an Aero Precision M4E1 enhanced upper receiver, then no additional parts are needed.

I used this on a new 458 SOCOM build. It’s a really nice handguard. Love the way it "wraps" around the top of the upper. The finish is perfect. Only issue is that you have to use the Aero barrel nut and it only has 4 gas tub holes. I had to order a shim kit as I could not get the correct torque with the ones in the kit.

Was looking for something for my RPR to upgrade the loose factory handguard. The AP Quantum does that very well. Just know that it does NOT come with a barrel nut and that has to be ordered separately.

This handguard is great, but unfortunately, I did not read the description that states that this is just for the handguard and does not include the BAR barrel nut that is required to install it. The barrel nut is sold separately. It's lightweight and has plenty M-lok attachment points. It comes with one M-lok rail attachment to mount a front sight (or whatever else), however that included rail piece it does not mate well with Magpul Mbus sights. Other backup iron sights may work well, and although you can mount the front Magpul MBUS sight, it cannot flip up or be pressed down. Whatever position the sight is in when you mount it, it will remain that way, you won't be able to actuate it up and down. I have MBUS sights, so that kinda sucks, but I'll just get a different type.

I purchased this to complete an Aero Precision M4E1 build I am working on. I am building a 6.8 SPC rifle. I plan on having a large diameter scope and like the lack of a rail on top of the hand guard to reduce the need for a high rise mount. M-Lock allows me to place rail sections where needed without extra weight.

Built a pair of AR-15's and the uppers I bought pre-assembled from another site. Sorry to say, what looked like M-Lok slots in the uppers were just slots in the uppers. I need somewhere to hang my can opener and mini-hibachi. So I found these on Gun. Deals and bought one, then when I saw the quality, bought another. Super fast shipping. Came with screws and an allen wrench, can't beat that! Top notch!

Can't go wrong with Aero Precision..have their hand guards on at least 2 of my rifles and have been extremely happy. I've recommended them to anyone whose asked when building their rifle. Best part was Optics Planet had best pricing and shipped very fast. Will be buying more in the near future.

This aero quantum handguard is a super piece for the price used it on a build with aero upper and lower and faxon barrel the combination of these pieces made a terrific functioning and a beautiful ar, only suggestion would be is to make sure to get the barrel nut it's not included.

I matched this 15” Quantum M-LOK Handguard to an Aero Precision M4E1 Enhanced upper. It was a perfect fit, with a tolerance so close, it couldn’t have been any tighter. The mounting is precise and allows for a secure fit that should outlast me. Optics Planet had an excellent price and their shipping was quick. I’m will definitely be a return customer.

Purchased a 7" version to replace a 9" over a 10.5" barrel. Very satisfied with both, but didn't anticipate adding a quick connect device to the barrel. Well made and M-loc compatible. Very pleased with purchase.

Super light. Super strong. Looks great. It’s a no brained. Optics planets price was 10$ than a blem from Aero, so what more do you want. I mounted it to an Arro enhanced upper and it fit tight and locked in place. I have two quantum guards and will probably buy another.

The hand guard is awesome and it came fast. It was an Aero product and they didn’t have it in stock. However, it was here and the status on the site was still waiting to ship. It would be nice if you keep the status up to date.

Very nice product. Well made. Fits nice and tight. Nice ceerakote finish. Just make sure you purchase their barrel nut along with it as it is needed to mount this handgaurd. Install was a snap after getting the factory barrel nut off.

Fit and finish was perfect. Install couldn’t have been easier. Used it for a 300 Blackout pistol build and I don’t regret it. It’s not too rough a bit not too slick either, allowing you to get a firm hold when shooting. Comes with one rail that mounts to the 12 o’ clock position for a front sight. It’s M-lok so there are tons of accessories out there that will mount seamlessly.

The Quantums are pretty thick, and it is noticeable. I like these hand guards because of how rugged they are though. Never had an issue. The fit well over most muzzle devices, so if you want that shrouded appearance, these work great.

Looks and feels good, can’t wait to get it on my 300 blackout build. Packaged well during shipping to avoid any scrapes or chips. Be sure and order an aero Handguard but if you aren’t using a enhanced upper.

This rail fits perfectly and is very sturdy! Finish is spot on and the rail is light enough. (I was not looking for a lightweight build). Rail fits the M4E1 chassis perfectly and has the look that I was after. I will continue to use these on future builds

I've used this handguard on three builds. I like the smooth look of the top without the picatinny rail. It does come pre drilled and threaded with a picatinny attachment for front sight post etc. This mounts directly on Aero's M4E1 enhanced upper without the need for a barrel nut.

For the price of a typical quality free float rail, you can get an Aero M4E1 'Enhanced' upper and a quantum rail. The way the rail mounts to the forged-in mounting on the M4E1 'Enhanced' receiver, you have a semi-monolithic setup. The rail is going nowhere. No flex, no shift, no twisting. And the rail is minimalist. No wasted picatinny rail running the length of the top of the rail. Need to mount BUIS? Add on the mounting tab. These, as their 'enhanced' rails on occasion, are my go-to rails for all of my builds. Simply excellent, high quality, and very affordable.

I got this and the barrel nut together. They clocked better than any handguard to date that I have assembled. The barrel nut came with shims if you need help with clocking the handguard to the upper reciever. I am planning on buying another one for my next build. Also I bought the cerakoted to match the Aero Precision upper and lower recievers.

Perfect fit on my Aero Precision AR15 M4E1 Enhanced Upper Receiver (fit on other brands of uppers may vary). Having eight M-lok mounting locations (12, 1:30, 3, 4:30, 6, 7:30, 9, & 10:30) offers virtually unlimited mounting options. Having no built-in rails lowers both the weight and the cost compared to quad-rail handguards (and more comfortable to grip). Magpul polymer M-lok rail sections are available in several lengths and fit the Aero Quantum rail perfectly. The only thing missing is built-in sling QD cups, but that is easily solved by installing a Magpul M-lok QD sling mount. Interior diameter easily clears my Superlative Arms adjustable gas block. Well made and quality anodizing (mine is the anodized black version). The 12” length is just right for a 14.5” barrel.

Purchased this model, in Black, from Optics Planet. They shipped it promptly and it was packaged well. The finish of the handguard is outstanding. No blemishes, mill marks or anything of the sort. Well done Aero Precision! The actual diameter of the guard works well for my hand and is quite comfortable. I would say I have a medium sized hand, no gorilla mitts here! There are more than enough attachment slots to accommodate a huge assortment of accessories. Mounting was simple and certainly secure with 8 mounting screws to attach to the barrel nut.

This is a beautiful add on to my aero enhanced upper! This item is well packaged no scratches no blemishes. This is my first AR build so it’s nice to see quality parts and to see how well they go together.

Bought this handguard for the Aero percision enhanced upper receiver. This handguard is rock solid. It come with 8 screws that fit up to the receiver very nicely! It is light and feels comfortable. It is attached to a M4E1 upper with a 20 inch 1/8 twist. With not having very many options for this upper, this a beautiful piece to attention to the collections. The m-loc seems secure. I have only added a bipod to it. Oh, there is a screw in rail on the top muzzle device end of the handguard. Seems kinda weird to me but if you have a reason for cool. I just didn't add it to the handguard AMD still looks nice.

Fits the M4E1 enhanced upper and looks perfect. Works just right with the enhanced upper or a mil spec upper, just need the barrel nut. Comes with the screws needed to mount it to the upper and a small rail section in cause you decide to put a front iron sight.

I bought this and had to wait a while cause it was out of stock. It didn't come with a barrel nut so I ordered the one that said for a dpms thread cause that's what I have. It was wrong. Luckily the gun shop I deal with just swapped it for the right one and I didn't have to send it back so make sure you get the right one. This one one of the few hand guards I found without a top rail.

The product came in quickly and seemed to be of good quality. Good job for optics planet. However, i had to return the product due to my own error. But OP made it easy. One phone call and it was handled.
