Magpul SL


A little to put on without a handguard tool but well worth the time! Rock solid and has a heat shield underneath. As usual, Primary Arms got it delivered very quickly!!

Magpul MOE Slim-Line Handguard - Carbine Length


Decided to replace the M4 style (actually CAR-15) handguard (which had no heat shielding) on an older AR. Have the MOE Slim-Line Handguard on another AR and really like them. Typical Magpul quality. Best 2-piece polymer handguard I've come across. Would not hesitate to use them again.

Super fast shipping


Great delivery as always!

Excellent !!!


I actually caught this handguard on sale which covered the cost of shipping. Best price of any of the sites I researched and I received the product in a timely manner.

Very cool


I read a lot of reviews saying these are hard to install without a D-ring tool. They do require a little more effort to install than standard hand guards but i had them on just a few mins just using my hands and a small screwdriver.These handguards look and feel great on the rifle.* Eohtech 512 and 552 will not work with these due to height of handguard above rail.

Great Handguard!


I really like this handguard, it really made my AR feel a lot more solid and I like how you can grip farther up compared to normal carbide handguards. It is pretty hard to get on even with two people due to the extra length but once it's on it's great!

Just for now...


I'm not a Magpul fanboy, let's state that now. They do make quality stuff and at good prices. For the most part though I think this thing is hideous, but fit and function is spot on. I just had to ditch the A2 guards on my 10.5 temporarily. This will be replaced soon I just had to divert money elsewhere. The next lo - pro gas block, and free float rail will be permanent. So if you don't care about looks and just wanna cheap alternative to stock guards it'll do the job.



Just what I was wanting. Quick shipping

Design Issues - Too High


The top portion has a design flaw!The top portion is slightly raised above the rail line, hardly noticeable until you actually lay it upside down. MY PERSONAL GRIP, is that have this nice indent in the front to let you know when you've hit the end of the guard. However, this "double" raise-above-rail-line causes the MBUS flip-up to not actually flip-down.Everything else seems to be an upgrade from their original MOE:- Feel is about right- Feels sturdier- Definitely slimmer- Gas Block cover for your protection

Great product


These handguards are just what I needed to upgrade my build! As always primaryarms had the best deal around. I bought this when there was a 15% off coupon can't beat it.

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! <br>Got it in faster than I thought, popped it on, looks clean and like it's called, 'slim'. <br>Feels great in my hand, easy to grasp. <br>Makes the AR pistol super easy to move around for CQ training.<br>Only down side, had to lose the forward sling mount on the A2 sight.<br>Nothing against the old clamshell style, still have it on my rifle, but on the pistol this looks made for it.<br>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.
