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!

Great and cheap

Put on an AR-9, light. Strong and great price. Will buy more

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.
