ohhunt free float quad rail handguard installs on standard mid length AR-15 rifles and allows for the attachment of tactical accessories such as bipods, grips, or sights. The free float handguard attaches directly to the receiver, without touching the barrel or impacting barrel harmonics, thus allowing for more precise shooting. 

The aluminum barrel nut is significantly lighter than steel barrel nuts, however it may be subject to damage during installation. We recommend using no more than 35 pounds of torque during installation. 

Please note that installation of a free float handguard requires additional gunsmithing tools and expertise. For questions regarding fitment or installation, Please contact us.

Includes: Free float quad rail handguard, aluminum barrel nut, castle nut, anti-rotation set screw, Allen wrench.

Compatibility: Not Compatible with Bushmaster Carbon 15 rifles serial number E18000+ unless Bushmaster barrel nut is used.

Honest review

These are incredible for the price. If you are snooty about brands, then go buy high end. These are perfect for any build and these install incredibly fast.


Accidentally gave at five stars instead of one star piece of sh

Not happy

Ar9 barrel is 5” exactly
This mlok (1st one in pictures) is 4.250”! Not 4.0 or 4.1”

Why does it matter? The threads are inside of the damn rail and you can’t do anything besides get a longer barrel or a shorter handguard. Good luck trying to add a suppressor whatever it was $23 wasted.

Awesome handguard, thanks!

Like it

It went on fairly simply. Seems to be well made. Perfect length on my AR-22 PDW.

4" handguard

Fast shipping, great handguard. Just what I was looking for. Best price around too.

4” AR handguard

I finally received the handguard.
No complaints with the handguard - it’s great!
The delivery from China was a bit over a month. Know that if the item is not shipped from within the U.S. it will take 5-6 weeks, but you’ll get it.
My experience with Oh Hunt’s items have been very good.
It’s a great value for your money.

Good enough

It works just fine. But it was the only option I could find for a 4 inch quaud rail. I don't like the method of mounting it. But it's all I could find. I am satisfied with it. The finish looks cheap probably because it was a cheap rail.

Love, Ohhunt handguards great product at a great price. Word of cation of it is not in stock here it will take some time to be shipped and received. If your not in that a real hurry like me it is fine.
