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

Great solid hand guard for the money. It looks nice, sleek, and slim. The finish on it was very nice. It did not come with any instructions, but it was not rocket science to figure it out. 5mm Allen Key for the screws, and 30mm crows foot wrench for the barrel nut.

The downside, which I subtract 1 star for, was that the hand-guard did not sit flush with the upper receiver, so the locking key did not sit into the groove of the barrel nut as intended. Instead of shimming the barrel and like another reviewer did, I filed the dust cover pin down. That allowed the handguard to sit flush and for the locking key to fully seat in the barrel nut. Other than that, it's a nice handguard and I won't mind buying another one.

Came as advertised. Love it.

Light weight but solid.

Bought this rail a while ago (a year or so) and never got around to installing it, until a few days ago. I installed it on my 3 Gun rifle since it’s a super light rail that’s free floated. Probably put around 600ish rounds through the rifle it’s on right now and the rail is solid. A few things keeping it from getting 5 stars though, you’ll need to buy a 1 3/16” crowsfoot to be able to do anything with the barrel nut. Once the barrel nut is tightened the rail locks up solidly and is ready to go. There were no instructions with it, but super simple installation, however the instructions would be nice to know torque values. I emailed PA and go the torque values for it. The barrel nut is from 50-55 ft-lbs (TDP spec is 30-80) and the cross bolts are 20-25 in-lbs and recommended with blue threadlocker. All in all, would get this rail again.

Great price so I got it. My other rifle has a BCM handrail. I was truly impressed with this, seriously just as good as the BCM. fit and finish is perfect, so I bought a second. Neither one needed shims, they both fit just right.

6 of my rifles have them!

Was a bit skeptical once I received the hand guard. Never dealt with an aluminum barrel nut before. A bit of reading was all it took to settle my fears, perfectly acceptable. After proper installation; I can say lockup is tight and there is no noticeable movement.

After a couple range sessions there has been no issues. Overall, this has been a great purchase. I have no qualms recommending it to anybody looking for a new hand guard.

After I ordered it I saw they said it weights 18 oz. I’m glad to report that it’s only 13 oz.

Unfortunately the anti roll tabs would not clear the upper receiver. Not sure if this is a one off issue but I wouldn’t order another one. I like the look and feel and it appears to be solid but doesn’t do me much good if it doesn’t fit.

So I'm trying to build out a budget SPR. Found this rail on sale for maybe 50 bucks. Don't quote me on that but it was super cheap and I had some bonus bucks so it basically cost me nothing. It's not going to have any lasers. It's not going to have a light. All it really needs to do is hold the bipod and I tell you what the fit and finish is great. Install super easy it locked up perfect alignment was perfect. This is not a $300 geissele super duty rail but it is solid as a rock and budget friendly.
