AimSports has come out with their new lightweight and solid AR-15 M-LOK free float handguard. The M-LOK has an inherent advantage where weight reduction is concerned, generously sized M-LOK cuts allow for maximum material removal while still maintaining structural integrity and durability, which aids in air circulation around the barrel for faster heat reduction. These handguards are compatible with USGI spec upper receivers. Anti-rotation tabs ensure that the handguard stays straight even over prolonged use. All mounting hardware is U.S. made.

Nice Rail

by -

I am pleasantly surprised by how nice this rail is. Steel barrel nut, easy install, anti-rotation tabs, and cross bolts that interface with grooves on the barrel nut so the rail can’t slide off. Rail height and alignment match the BCA upper, perfectly. The rail sits over a Diamondback middy barrel and Radical nitride steel set screw gas block (all also bought from PA). Finish seems good and is a bit darker black. The mlok slots seem to be in spec with Magpul rail sections etc. The only negatives I can think of are mildly sharp edges around the 2 cross bolts and it sure has that “metal” smell, that will probably fade away after a while.. Box says made in China, but it’s actually a nice rail. Got it on sale, however even at PA’s listed full price, I’d say it’s still a 5 star..

Great Products and Customer Service

by -

Have used several of these rails in different lengths. They are good quality for a great price. The way they mount up is also very easy and secure. One of the rails I bought came with a bad nut. I contacted Aimsports customer service and they sent me two new screws and nuts and a torx wrench at no charge. I received them in a few days. I have bought stuff from other companies and never got a reply to my emails. I will continue to buy Aimsports products!

You dont get what you pay for. You get more.


I was a little concerned given the price, but after installation I was more then satisfied. The barrel nut worked great and was included. It has two anti-rotational barbs to help stabilize the guard on the receiver. It is extremely slim in that the gas block touches the bottom (it is a low profile CLAMP style), but I cant blame the guard for that. Be careful with the screws that lock it into the barrel nut as they are fairly easy to strip (screws or nuts). The best way is to screw one tight then the next and back and forth like that until in they no longer tighten under moderate pressure. Looks great and at this price it can't be beaten.

Light weight quality

by -

Packaging was great, and the quality is excellent for what you pay.

New favorite!

by -

I bought this for a low cost build, so pleasantly surprised at the weight and install. I slipped it together in about 5 minutes, once the gun was built my wife took it as her new favorite! ;( For a third of the money for my old favorite, the Samson Evolution I'm sold on this product. Wow is it light, tight and secure! Oh , and it is super slim!

Sturdy, slim profile at a great pricepoint

by -

Very nice handguard for the price. I know there are some advantages to higher dollar handguards, but for this level of savings, I will take the less sturdy finish. My AR's are for hunting and are not subject to much abuse or competition and this rail fits the bill nicely. It is sturdy, but extremely slim in profile, so you may run into situations where the M-lock attachments may not fit exactly where you want them on heavy profile barrels. Again, a small price to pay for the savings that I can apply to other parts of my build.

Great product at a great price

by -

Excellent fit and finish. Attached easily to my recent build. A friend who has worked up many uppers and helped me put mine together was impressed by this handguard and will be using them on some of his next builds. Very sturdy feel, with a slim profile. I am very pleased with this purchase, and with the great price and fast shipping.

Great value, light weight

by -

Bought this for my recent build. It is very high quality for the price! Lightweight. Came with the barrel nut and hardware. Simple to torque down the barrel nut without worrying about aligning the gas tube. The notches keep it aligned perfectly to the upper receiver. Watched the youtube video from the manufacturer and install took 2 minutes.

For a budget build this is a great option

by -

I gotta say, I really like it. For a budget build this is a great option, and the anti-rotation tabs at this price range is a very nice addition. Looks good, feels good, light weight, and mounts with a steel barrel nut. Nice

All you need, amazing bang for your buck.

For a function-based rifle, this is perfect. I was very hesitant to buy this based on the price. It had to be crap, right? It's not. It looks great, feels great, works great. I can't believe it was less than $50. I almost bought the Daniel Defense handguard, but am so glad I saved the $150-200. There were 2-3 tiny spots where corners were a little dinged or some finish was missing, but they are VERY small and only noticeable under close inspection.<br><br>I installed it (super easy install) on a Del-Ton 16" carbine kit. I haven't fired it with the new handguard yet, but can't imagine it causing any issues. If you aren't building a man-jewelry, beauty rifle, and only care about function, buy this. The barrel nut does not require indexing, just torque it down. You will need a 1-1/8" wrench to tighten it. Any future ARs I build will use this handguard, unless I just feel like spending extra money or want something specific that it doesn't offer. But for now, it does all I need and looks great!

Good for what it is

by -

Good for what it is. It gets hot WAY faster than my Midwest industries handguard. The MLOK slots at the 1, 5, 7, & 11 positions are not completely to spec. the MLOK T-bolts sit crooked in these slots. but the 3, 6, & 9 MLOK slots are just fine. The top is not T marked but neither is my upper so no big deal there just something to note.

Good, but Noisy

by -

Fit and finish are very good. I like the way my rifle looks with it. No issues what so ever with installation. My only complaint is the loud ringing noise when the weapon is charged without holding onto the hand guard. Other than that, I really like this product.

Don't let the low price fool you

by -

I was skeptical how good this handguard would be given the price. No timing on the barrel nut. Anti-rotation tabs fit a standard upper receiver perfectly. Very sold feel once mounted. Extremely easy install. I'd say you can't beat this for the price. Great bang for the buck.
