The MOE Slim Line Handguard for AR-15/M4 firearms combines the light weight of a standard handguard with modular flexibility of a rail system in a slimmer package. M-LOK slots at the 2, 6, and 10-o'clock positions provide space for 1913 Picatinny rail sections or direct mount M-LOK accessories. Reinforced, heat-resistant polymer construction provides durability while a large front extension and lower lip protects from the hot front sight gas block assembly maximizing useable handguard length.

Great Product


Very high quality product. Impulsed ordered Christmas day, just received this morning. After I ordered I realized that my Yankee Hill gas block and flip up sight ( would need it's sling loop punched out which took all of 30 seconds. After that I was off to the races, this thing was a tight fit. Very tight, top went in no problem, bottom needed a little more effort (as per Magpul instructions). After I got them in I noticed two things. That they fit tight and felt great and much noticeably slimmer than standard hand guards. Then I noticed that my front sight (which is part of the gas block) would not flip up...crap!After making 3 notches with a dremel which are hardly noticeable everything fits snug and the sights flip up no problem. Just waiting on an M-LOK QD sling mount to show up and I'm set.

Great Ergonomics


Very sleek and ergonomic. Only wish they would've made a midlength version.

nice looking handguard


Good quality, takes a little tweaking to get it on , but is rock solid. Will probably buy more for future builds.

Good Handguards


Some IssuesOverall very good. I did have to cut about an inch off the bottom section to clear the stock FSB sling mount. Also had to cut off a tab of the upper heat shield to accommodate a rail section and flash light. So some small dremeling may be required.

Great feel and endless mount possibilities


(Ruger AR-556) I love these guards but holy smokes they were tough to get on! Luckily the delta ring on the Ruger is threaded so you do not need the tool to back it off (you just twist it all the way back.) The feel is sturdy the shape of the grip is perfect for my average sized hands and I love the coverage over the gas block. Primary Arms has the lowest price for these guards as well. $34.99 from Magpul $39.99 at Bass Pro & Cabelas - $33 at Primary Arms.

If you're looking for a great look and feel, this IS for you. Perfect for an AR pistol.

This is great!
Got it in faster than I thought, popped it on, looks clean and like it's called, 'slim'.
Feels great in my hand, easy to grasp.
Makes the AR pistol super easy to move around for CQ training.
Only down side, had to lose the forward sling mount on the A2 sight.
Nothing against the old clamshell style, still have it on my rifle, but on the pistol this looks made for it.
If they could do this in a wood grain, I would get one for the AR 15-45 I am going to build. Give it that old style Thompson appearance.

Great d ring handguard replacement

Great product for those of us who want to upgrade the look of our rifles that have old style handguards. Fit and finish is perfect as you would expect from magpul. One thing you need to consider is that the front sling keeper needs to be removed to install this handguard. If it is riveted in like mine was, that is a real pain to take out. As always, primary arms had great prices and really fast shipping.

Great hand guard upgrade

Most of the rifles in my collection have fancy monorail hand guards and those have their place. But, a good ol’ A2 upper with a fixed front sight is my go to truck gun. I replaced the stock plastic handguard with the Magpul MOE at first, but eventually swapped that one for this slimmer version. I’m a large man with large hands, so the MOE fit alright, but the extra slim fit of this handguard, combined with the extra room it adds to the front, is where it’s at. Plenty of room for an IWC extended light mount and any other MLOK extras. They are a tad tricky to put on at first, but if you are patient and squeeze the extended tabs from the lower portion into the tabs from the upper portion first, that will allow you to install it a little easier. Good purchase and quick shipping with great service, as always from Primary Arms.
