Are you attaching this handguard to a standard threaded upper receiver?
Make sure to select "Yes" under the BAR Barrel Nut option above (shims included). Our handguards use the BAR interface and do not work with a standard barrel nut. If you are using our M4E1 Enhanced Upper Receiver, no additional pieces are needed. Purchased with a handguard, the BAR Barrel Nut is $20 ($40 when sold separately).

*Please note - This handguard is specific to the AR15/M4E1 platform. It is not compatible with the M5 .308/M5E1 platform.

Does not fit Superlative Arms piston block Review by Andrew

Handguard looks and feels great, comes with shims for proper alignment. However it is too narrow to fit the piston block of a Superlative Arms gas piston system. (Posted on 9/9/2016)
Looks great, MBUS easily modified to fit. Review by Myke J

I ordered a 12" BLEM for my pistol build and USPS lost it, but Aero took care of me by shipping out an unblemished replacement right away. It's the perfect size for my 10.5" pistol with a 3.25" flash can installed. A Magpul front MBUS does fit on the rail section, but has to be installed in the up position as the rail section fits too tightly to the rail to allow the release tab to operate. With a few mins of work with a Dremel, file, or razor knife you can shave the insides of the MBUS release tabs down to clear and it will function perfectly. (Posted on 9/3/2016)

This rail looks great and feels great. Zero problems with the install. I bought the 15" BLEM, I had to look very hard to find the imperfections. Thank you AERO for quality products. (Posted on 7/20/2016)

Running the 15" M-LOK:
One of the best, in my opinion! I cannot get over how great this handguard looks on this build. Tight fit, smooth transitions, precise lines, excellent finish... and to top it off, I bought one of the "blems". What blem? This is the question I ask myself when I tried to find an issue in manufacturing. Amazing product, amazing company, Aero out of the gate, and now, Aero for life! Great work guys (Posted on 7/20/2016)
Perfect rail except..... Review by Jason
Quality

This rail is exactly what I think most people would want. Reasonably priced, quality materials and perfectly machined. MULTIPLE angles to mount accessories. So this rail is basically perfect EXCEPT, the inside diameter. I was hoping my Adams Arms XLP gas block would fit. The gas block, piston rod, and bushing all contact the inside of the rail. After some dremel work it does fit. If the inside diameter was just slightly larger it would fit. Assuming the gas block would fit I would assume also that suppressors would also fit with no problem. Overall I am happy with the rail, I just wish I did not need to machine it to fit a piston system.

*side note, the barrel nut did not accommodate the piston system either. I used a barrel nut from another manufacturer (which is nice that all the mounting screws are in the same location). The provided barrel nut would also need to be machined out to work with a piston system. (Posted on 7/14/2016)
Fantastic rail Review by Jason

I was reluctant to pay $200+ for a rail to put on my first ever build. Then, one day I got an email from AP telling me about these new Quantum rails. I checked them out and jumped on the chance to get a 15" to go on my 18" barrel on my standard upper, for just over $100. The quality is excellent. Installation was a breeze. Shipping was fast. My dad bought one for his build also. The circumference is perfect for my big hands.

The only issue we had, on my dad's build was the Magpul MBUS front sight was very difficult to install on the supplied picatinny piece for the front end of the rail. The picatinny piece is a little wide. We finally got it installed though.

This is the only rail I'll ever use. (Posted on 5/29/2016)

I used the 12" Quantum handguard with an M4E1 upper. Fit tight like a customer fit glove! (Posted on 5/26/2016)
Great Product Review by Joseph

Had been wanting to upgrade to a free float for awhile, but couldn't convince myself to pay $200+ for a 15" rail. When I saw this one for half the price, I instantly put in an order. I wasn't disappointed when it arrived either. Rail looked and felt great once it was installed.

The only downside is that a Magpul BUIS will not fit. I wish the earlier post stating so had been posted a few days earlier, or that there was a note in the description stating this. (Posted on 5/24/2016)

Used this handguard for a new build and was amazed with how quick and easy it was to attach to the enhanced upper. Will use on all future builds. (Posted on 5/22/2016)
Great addition to the product lineup! Review by Chris

Right out of the box I was pleased with the quality of this handguard. It looks very clean with a 15" rail on a 16" barrel. The only negative is that there is not enough clearance between the handguard and supplied front rail for a Magpul BUIS. I rested on the ARMS flip up and I've been happy with that ever since. Other than that one snag I'm pretty happy! (Posted on 5/20/2016)
