Great product

Great product, easy to install, shipping was good ,wish it was faster but it was on the time frame I was told.

Fair for the price.

If you compare this rail to a comparable length quad from the likes of MI, I'd say the price is fair. The weight is good, the machining is good, but the anodizing is much more fragile, very easy to scratch. The rail went on well, the barrel nut withstood 50ftlb of torque perfectly fine and after a little wiggling and adjusting the rail lined up almost perfectly to the upper receiver. This is an excellent rail for building a CQBR mk18 clone and not giving Marty Daniel's your money, but if you plan on dragging an AR through the dirt in more than a few matches, something more authentic would be best.

Great hand guard for the price will definitely be buying more

Wrong color.

After emailing OhHunt stating wrong color was shipped. They replied that the Coyote color looks black unless in the sun. So basically not correcting the problem. So I recieved black. Don't expect good customer service with this company.

Dear Customer,
There will be a little bit color differences between different batches of Coyote Tan. in bright light you can clearly tell it's brown, not black.

If you’re looking for a budget RIS ii aesthetic then this is a great choice for sub $100. Locks up tight and seems to be a solid handguard. My only complaint is the finish is pretty shiny compared to the real deal, and it doesn’t come with a barrel nut wrench. (The genuine DD barrel nut wrench will NOT work) But I found that a castle nut wrench will work or even better a BCM barrel nut wrench. If you’re wondering if you should pull the trigger then this is your sign to do it.

Love it but..

Received the hand guard faster than expected. When I was installing it, I noticed I was missing a few screws that attaches the hand guard to the barrel nut. I was still able to install it and it fits snug. Rails look and work good. Was glad I found this company because I LOVE how the mk18 hand guard looks. Saved me a lot of money for sure.


I wanted to make the MK18 look but don't have the MK18 $$$ and this knocked it out the park!!! Took it to a gunsmith for some additional work and she swore it was the OM version! Great work Ohhunt! Bout to get one for my 300 BLK build too!

Almost gave 4 Stars

I have the black and coyote tan. They lock up tight to the upper. I still haven’t figured out how it works, but it does. I was going to go fours stars when I received the coyote tan because it was more of a shiny charcoal. But once I took it out of my shop and outside, the coyote tan color showed up. Integrated QD would be nice. I would buy another if the need arises. Looks good!

Awesome quality!

Product came fast, and is of great quality. Fits perfect and holds all items mounted to it with no issues, and is a solid addition to my MK18 build! Highly recommend!!
