The Expo Arms® Combat Series™ AR-15 Handguard is a brand new model that comes with a ton of improvements over a standard handguard. With 7 sides of M-LOK compatibility, you can easily set up your rifle how you want with grips, lights, and other quick attach accessories. Each row of M-LOK slots are staggered to increase the overall strength of the free float handguard while also reducing weight. Additionally, the top picatinny rail features relief cuts to further reduce the weight. At the rear of this M-LOK handguard are low profile anti-rotation tabs that are compatible with Mil-Spec upper receivers and prevent the handguard from working loose of the barrel nut and affecting accuracy. The barrel nut is constructed from 7075-T6 aluminum and uses a dual screw wedge to lock the handguard securely in place. Comes with a barrel nut wrench, so you can easily upgrade your rifle as soon as you take it out of the box.

Send it! Buy it!


Liked the look. The price was right! The fit and finish are top-notch. The handguard mounted perfectly with the BCM upper with the supplied Aluminum barrel nut. The handguard locked onto the barrel nut very well. The mating tabs allowed for the picatinny rails to match exactly. I was looking for a "slim" handguard and this Expo Arms unit filled that bill perfectly! Recommended.

Nice light handguard.

High quality - Great fit


Looks to be made by CMT and certainly feels/fits/looks like a much more expensive rail. I free floated my DPMS Oracle with this rail and now it looks so much better. Every part of the rails fit and finish impressed from the locking hardware to the barrel nut. I would buy more of these without hesitation.

Great product


After recieving and installing this handguard I felt like I stole it only paying a little over $100. Slim, light, awesome finish, fits tight and true. My only hang up was that the included barrel nut makes it impossible to torque using a standard armorer's wrench or similar tool. Other than that, I have zero complaints about this handguard.

Great rail


Ordered this rail for my very first build. It's made very well and looks great, and was packaged very goodm

Solid handguard


Tabs were a little snug. Two minutes with a file made it fit. Very solid lockup. I torqued the non-indexing 7075 barrel nut to 40ft/#'s and the wedge screws to 45 inch/#'s. Very solid, very traditional matte ano (don't expect to match mega/zev made lowers). Matched BCM upper fine. I can reasonably say it's a best value in its price range. Other, VERY similar setups run $70 to $90 more. Instructions can be found online but not included. really. Feel confident buying.

Exactly what I was looking for!

Prior to this rail I had a mid-length magpul hand guard and needed more real estate for future attachments. While this provided the necessary space, I did have to modify it slightly. There are tabs on the rear of this rail that mate up to the lower receiver that raised it just enough so that the screws to lock the rail in place didn’t sit correctly. After grinding those tabs making them flush, it fit perfectly. Other than that minor detail. This rail is amazing, light weight, looks good, and allows much more space for future attachments! For reference as to which lower I’m using, it is a spikes tactical.

Solid rail for the price!

Very solid rail with very positive locking mechanism.

Best Value Handguard Out There


This is probably one of the nicest handguards out there for the money. This handguard weighs 13.4 oz even though PA CS will state the weight is 18.2 oz. The barrel nut is super light and the weight is from the thicker than normal handguard extrusion. So, it should be stiffer than most normal (not suppressor hiding) sized handguards. Instructions are not included, but the another one of the OE's handguards says to torque the barrel nut to 50-70 ft-lb, and the clamp screws to 45 in-lb. Finish is matte with a medium texture and nicely scratch resistant. The slots are nicely chamfered and won't shred one's hands. Great value.

Excellent Product


For the price this rail is hard to beat. Great quality and fit, nice finish, feels good in hand. I am a huge fan I have this on a SPR 5.56 build and am very pleased with the look and style!
