Most Helpful Positive Review Its decent for a handguard but good for the price
Installed the mid length hand guard on a M&P 15 sport installation was easy. Finish was a little rough. Barrel nut is aluminum not a fan of that. Top of the rail on hand guard is a little lower than the upper receiver. Still able to adjust front sight in. As far as function it does what it is intend...

Most Helpful Negative Review POS China Junk
Threads are soo loose (NOT Matched) that the rail will skip over a thread or two when rail is bumped sideways. 0.019" difference between male and female OD vs. ID at the barrel nut rail engagement. China wants you to have inferior equipment, intentionally built this way to render your weapon inopera...

Don’t Purchase

by Deago, Verified Owner from OH, United States Written on November 27, 2022
Purchased this handguard for a 4.5” 9mm upper. It fit okay and seemed sturdy enough. Cracked a piece of the barrel nut off while mounting. Should have stopped there.

Torqued the barrel on and dry fired it over a few days. Within that time, the barrel had came loose so I removed it, degreased the threads and applied some Rocksett. After a day or two same thing happened. There’s too much slop in the threads for Rocksett or red Locitite to get a good bond. Don’t waste your time or money.
Pros:
  • Cheap
Cons:
  • Fit
  • Functionality
  • purpose
Would recommend: No

good but shiny

by Danh70, Verified Owner from WI, United States Written on August 1, 2022
Price was great and the shipping was very fast but it was not really a matte color and had too much shine on the Finish but as far as always goes it's not bad for the price you pay just expect to you probably have to repaint or deal with the extra gloss

Solid Build - a little heavy - slot issues

by LeGen, from TX, United States Written on February 23, 2022
First off - I need to quit buying full length quad rail handguards! The extra (3) rails add a lot of weight and I will never use them all, my bad.
Clean appearance, solid feel. Includes the barrel nut, Good price point.
I have not had time to install it yet. Stalled on finding a barrel I like for my next build.

If you're looking for a heavy build (target, long range etc.) this is fine.
If I was tramping through the woods hunting I'd go for a lighter handguard. One rail and then use the MLOK slots in the unlikely case I needed to add lights/lasers/etc.

Don't like! The MLOK slots are at a 45 degree angle. I did not notice this before buying.
My accessories with 2 nuts will not fit into the slots properly! I was thinking about putting backup sights on the 45 degree portion, but no joy!
Pros:
  • Priec quality
Cons:
  • 45 degree MLOIK slots
Best Used for:
  • Target due to weight
Would recommend: Yes

Great product

by Garrett, from AL, United States Written on March 10, 2017
Love the aim sports quad rails. The rail was extremely easy to install, and it has a great look on my rifle. The handguard definitely had a durable feel to it, and although I have not put it through a lot of field testing yet, I believe it will keep it's functionality for a long while.

Great product for a great price

by Don Le, Verified Owner from CA, United States Written on November 29, 2016
This is my first ar 15 build and the product is great. The rail is solid. It lined up perfectly with my upper receiver. The construction for the float is well made. I will get the rifle length for my next build. The barrel nut was not as well made because the holes where the tool were placed were bent due to stress pressure. I had to carefully apply the torque to not damaging the nut too much. However, once the nut is installed, it was easy to tight down the float. There was only one screw to hold the float to the barrel but it did its job. I was satisfied with the product for the price I paid.
Pros:
  • Fit & feel great
  • Float is well made and sturdy construction
Cons:
  • Barrel nut is lower quality
  • Only one screw to hold float to barrel nut
Would recommend: Yes

Cost effective

by Griever, from CA, United States Written on November 17, 2016
I knew next to nothing about ar's but after a little research and common sense I found it extremely simple and easy to do provided you have the right tools. You will need an armorer's tool/barrel nut wrench and a vice to equip this rail. I've heard complaints about the barrel nut being aluminum. I don't really see the problem. For the price, it's definitely a nice rail for a budget build and would absolutely recommend it to someone else looking to upgrade their ar on a budget.
