Expo Arms® M-LOK AR-15 Handguard - Black - 15"

This just barely fits over an Odin Works adjustable gas block. The gas block touches the inside of the handguard so it won't free float. Plus the handguard is flimsy and easily flexed.

I have a few handguards from Geissele, a few from BCM, and a carbon fiber handguard from Faxon. I'm just as happy with this handguard as I am with all the others. The finish is impeccable, and it fit my upper receiver perfectly. Buy with confidence.

Such an easy handguard to install. Barrel nut does not need to be timed. Set to a standard torque value. Slide the 6061 Aluminum handguard on. Index the anti-roll tabs with the upper receiver to perfectly align the upper and hand guard into a seamless mono-rail. 3 Steel bolts and a steel wedge nut, which locks into the channel of the barrel nut, prevent the hand guard from movement or slipping forward. All 3 bolts lock the hand guard down solidly. I don’t worry about the hand guard failing, coming loose, bending, and I just train hard. 100% reliable every time. The M-Lok system gives me unlimited attachment points. But, I just put one good Surefire light on it, LPVO, steel folding front and rear BUIS to keep things simple and lightweight. It is a shockingly lightweight, simple, bomb-proof, affordable, and reliable design. This works. Buy it.

I have a few of these an 11 13 and a 15 inch handguard they work great they securely fit alot of space for attaching things extremely well made I have no complaints

fit's tight, no play.

Awesome unit especially for the price. Looks like Expo is doing some big things but the price is staying down! Good product. Would recommend and would buy again.

Seems to be well made. I had my gunsmith install it on my Bushmaster as well as a BCM free float handguard on my PSA. He said he could tell the difference in quality between the two, saying the BCM was better quality but that the Expo was well made. I think it will be fine for what I need.

I replaced the handguard on my 300BLK rifle. Took less than 20min. Paired it with a new set of M-LOK bi-pod. Great product.

I am very impressed with the quality of this rail. I normally use Atlas R-one and S-one rails. For a cheaper build; this is absolutely perfect. Value is much greater than its cost.

Nice handguard.
