This Quad Rail handguard is designed for fitting the MK18, .223 rifles, which is applicable to field combat practically.

  1. Clever top/bottom two-piece design with integral spinal cords/alignment housing for great fit.
  2. Free-floating barrel design for increased accuracy.
  3. Great accomodating capability for the accessories Installed on the rails, and it allows the individual operator to handle freely.
  4. The interrupted picatinny top Rail Platform with the FSP cutouts provides ample space for optics or includes removable front triangle flip sight. NOTE: The bottom rail does not have a cutout, not fit for the front sight base with bayonet lug.
  5. Desert Tan color is a lighter tan color than typical FDE (Flat Dark Earth), while Coyote Tan color is darker than FDE. Coyote Tan color is not exactly the same from batch to batch, sometimes it is darker and may easily mistaken for black. We will update the picture when the color difference is large.

SOLID

Put the black 12” on a rifle build and for the price it exceeded my expectations. Very solid, bolted up strait and the quality is 10 out of 10. I had a gas block issue and had to take the handguard off and it went back on no problems and was able to still torque down on the bolts just fine. Will buy again on next build.

this shouldn’t leave factory

it had some sands all over including inside thread and threads on 9, and 3 oclock were drill dirrerent depth. one was threaded all the way. one was not. and mk18 9.3 rail had extra anti-rotation washer but this one didn’t . mk18 rail was even better than real dd . but this one was off concentric too. finish was very rough. every bolt I could feel it was grinding agaist thread because of fine sand i could not remove from the inside of thread

Excellent handguard for the money.

In this price range you would be hard pressed to find a quad rail that both looks nice and is as rigid as this one. The machining is also flawless. For anyone wondering the barrel nut is Castle nut profile. And fits the DD barrel nut crow foot. Mine torqued to 55-ft lb DD spec, all other associated hardware torqued at 30 inch pounds. Rock solid. I have two of these. A 9.7 and a 12.7. both on mid-length uppers.

Sketchy

Kinda wierd how after I ordered i had suspicious activity in my account later, and I order parts online all the time and only happened after purchasing the rail, which doesn't fit properly without modifications...total bummer experience all around -10/10

9.6 Quad rail on a 9mm AR pistol

Was a little on the fence at first, but turned out to be even better than I thought. 10.5 barrel with Dead air can.

Faithful clone of the original

You won’t be disappointed by the quality when you compare to the real article. A scratch hardness test of the hardcoat anodizing meets the milspec based and based on experience I expect the thickness finish is correct. Visually the handguard finish is comparable to an Anderson upper/lower with a chalky but consistent color.

MK18 handguard

Swapped out my RIS III MLOK rail with the Ohhunt MK18 handguard design on my DD DDM4V7 and I love the way it looks and feels. Definitely would recommend

Very Nice

The fit and finish on the rail is great. The Coyote Tan is very beautiful rail! I've never handled an DD rail, but this rail does the job! HOWEVER the barrel nut is very soft. I ruined mine trying to torque it to spec. Ended up buying an authentic DD barrel nut which worked great. That created down time, and another expense. Proceed with caution when torquing the supplied nut, and prepare for the worst. Other than that I'm very happy with the rail!

Great quality

Great quality, every bit as functional as DD but 1/4 the price. Recommended gas block didn't fit, had to reduce underside dimensions on a belt sander and refinish.

Bad quality

Machining marks and blemishes all over the handguard. Does not line up good
