AAA+++++ Best handguard on the market!
by Don -
Wow, this is hands down my favorite handguard to date. Very light, and the small diameter keeps your grip tight and your gun under control. Looks awesome too. Fit and finish is perfect, AAA+++
Nice hand guard
by Danno -
Great looking handguard, nice and lightweight,. Only downside was it will not fit my PSA billet upper receiver,. The lower and tangs that slide onto the upper are blocked by the extra billet material left by palmetto State armory. I can't blame AP its a nice guard.
NOT FOR BILLET UPPERS
by Danno -
Even though it did not fit my upper at all, it was a nice built hand-guard. It will NOT fit a billet upper. the wings that fit over the upper to tie it into a seamless looking design do not fit some uppers, especially billet that may have extra material. Wish It would have fit my PSA billet Upper, I like the design and weight.
Nice rail great fitment and finish unusually heavy barrel nut,
by IPDAILY -
Nice lite rail the fit and finish are awesome. However the barrel nut is unusually heavy. I would pay more to have a less heavy barrel nut include. Aero should take a look at maybe selling or providing an aftermarket part for their rail that weighs less.

I ourchased this handguard on sale. I love it. Very light and smooth. The fitment is excellent. I mounted it on a Colt AR9. I will state that even on AR9s you still need to clock the barrel nut like you are running a gas tube. You need a slit facing at the 12 O'Clock position. It allows the wedge locking tabs on the bottom to seat properly so that they are flush. Excellent product and would buy again.

I have often wondered why nobody has made anything like this before. It just makes no sense to me to buy a Quad-rail and then add weight covering them up trying to make it more comfortable to hold. And then using very little of all that Real-estate to actually attach stuff to.This rail is bout perfect in my book. Very comfortable to hold, lightweight and Just enough room in front of a scope mount for my brass catcher, and a short rail in front for BUIS if I need. Come-on AERO ! We need one of these to fit the M5 !!!
My GO-TO handguard now!!!

This handguard is great!! I now have two installed on rifles I have built. I love how the top is rounded without any sharp edges so your hand just fits perfectly no matter your front hand grip style. Extremely light for a 15" rail. The attachment system doesn't seem like it would be one to loosen up at all. Great job AERO!!!
<br>PA seems to have the best price on these as well. These seem to be hard for them to keep in stock so if you're looking and its in stock, you better buy it....
Come Back in stock soon.

Great product from a great vendor. I had a small concern about my order and primary arms was very quick with respond with a solution. Will continue to buy here!
Excellent Light Weight Rail, Easy to Install
The Aero Precision S-One is extremely lightweight, yet rigid and stable. The diameter seemed a little bit on the small side when first taken out of the box, but the hand guard feels very comfortable in my support hand now that it is mounted
<br>Installation was easy and straight forward due to their innovative, novel mounting system; however, I would recommend watching their YouTube video before doing so as they offer some good tips and note the differences from a standard barrel nut. It is important to get the provided barrel nut wrench properly and positively engaged with the barrel nut, which may be slightly difficult depending on your bench setup but not overly so. It may take a few shims to get proper alignment within the 35 to 65 ft-lb torque specification, but I was able to do so at the lower end of the torque range and the barrel nut is a lot easier to align than a standard one.
<br>Excellent product. Highly recommended.
