As one may have heard, I was building out a lightweight AR pistol and was in need of a lightweight handguard. Along comes Dark Hour Defense with their Magnesium Darklite M-Lok handguard. If you haven’t heard of Dark Hour Defense, they are a sister company of V Seven Weapon Systems. Dark Hour Defense is more of the “not as fancy” line, but still using the same technology and quality of V Seven. This makes the Dark Hour products more cost effective for the end user.

I decided on the Darklite handguard in the 9.2” length. I chose this length because I was using a 10.5” pencil barrel. Essentially, I didn’t want the handguard to extend over the muzzle, but also wanted it to cover the gas block. The 9.2” Darklite turned out to be just perfect. Dark Hour also has a 7.1” as well as sizes out to 18”. Outside diameter on them is 1.5”s wide and 1.97”s tall. The 1.97” height is due to the full length top rail. Inside diameter is 1.3” wide and 1.55” tall.

The Darklite handguard is super light! The 9.2” comes in weighing 4.23 ounces, on my scale, without any hardware. The barrel nut adds in another 1.13 ounces. Add in some mounting screws and the total weight is 5.64 ounces. I will mention that the weight listings on the Dark Hour Defense website are really close to the actual weight I measured. To get this lightweight handguard, Dark Hour uses an aluminum magnesium alloy that is 30% lighter than standard 6061 aluminum. It appears to be just as strong, if not stronger. Remember, this handguard also has a full top picatinny rail. The barrel nut is made from 7068 aluminum, which is harder and stronger than 7075 aluminum, but weighs less than steel by a good margin. All one needs to really know is that these are super light and strong.

The Darklite handguard is pretty normal in other aspects except one. As noted before, it is running a full top picatinny rail. The M-Lok slots are at 3,6, & 9 o’clock. As of now, it is only available with M-Lok, because that’s the standard in my opinion. Instead of anodizing, Dark Hour uses a plasma deposition coating that gives a “tough ceramic-like coating with superior wear resistance compared to anodizing.” I’ll agree, this E-Cote finish, as they call it, is super tough. I haven’t even scratched it. Also, I had a QD point mounted to it and when I removed it, you couldn’t even tell it was on the handguard. It didn’t even leave a chip or indent. I kind of wish the Darklite had a QD point built in. That way I could connect a sling without adding the weight of the QD mount. The black color of this E-Cote finish matches the rifles anodizing very well and I like the durability of it.

Installation of the Darklite handguard is pretty normal also. Install the barrel nut with the supplied wrench. YES, it includes a wrench! This is one of my favorite things. Every other manufacture, please do like Dark Hour Defense and include a barrel nut wrench with your handguards. The barrel nut may or may not need shims, mine was on the tight side without them, but still in specifications for torque. When installing the handguard tube, you may need to tap it on with a rubber mallet, or heat it up slightly. It is a nice snug fit. I just tapped it on and it worked fine. Dark Hour also includes a locator pin, so if your upper has this provision , you can use it for added rotational stability. I didn’t use the pin and have not had any problems with the handguard rotating. Lastly, install the 6 torx screws to spec, and off to the range you go.

As usual, I’ve been trying to use the Darklite as much as possible. I really like it, but I like slim handguards, and at 1.5”s, it is just perfect. The Darkilite is a no frills, super lightweight handguard. They smoothed it all out and put angles and radiuses where they needed to be, like on the muzzle end of the handguard. The top rail portion is even pretty smooth, which is not an easy task with all those slot cuts. The price won’t kill your wallet either. At $195 for the 9.2”, it’s a great deal. Yes, longer ones cost more, but they are still a reasonable option for what you are getting.

The Dark Hour Defense Magnesium Darklite handguard is well worth checking out. You are definitely getting a quality lightweight handguard at a reasonable price, at least in the lightweight product category. I think Dark Hour Defense will be doing some more nice stuff in the future. Definitely keep your eye on them for cost effective lightweight products.
