Most Helpful Positive Review Solid slim hanguard
I did not read carefully and didn't know this handguard only fits mid-length rifles with round retaining caps (not triangular). Considering most (roughly 80%) mid-length AR's use triangular caps, Magpul should have made a triangular or universal version. Regardless, the handguard itself fit together...

Most Helpful Negative Review First dud from magpul
Website doesn’t tell you triangle handguard cap wont fit. Big strong Marine veterans follow directions well and so did I, effectively snapping the bottom handguard in half. Wont even bother sending it back so i can show my buddies that a magpul product can be broken with my grip strength. On a po...

round cap only

by Matt, Verified Owner from VA, United States Written on May 23, 2025
Doesn’t specify that it requires a round handguard cap, so if you have a triangular one like I did, then you’ll have to pay a gunsmith to swap them out to use this handguard. Magpul website says it’s only for the round cap, so this review is more for OP leaving necessary information out, than for the product. Outstanding handguard, much more slim and streamlined than the original MOE handguards, MLOK slots on the sides and bottom offer a lot of options, and it manages the heat well during long range sessions. Highly recommend!
Pros:
  • light weight
  • thin
  • Manages heat well
Cons:
  • Round cap only
Best Used for:
  • Updating A2 handguards
Would recommend: Yes

Works and looks good!

I replaced a quad rail on my M&P 308. Use a solid handguns removal tool and br careful with the gas block. All is good.

Does not fit triangular front sight assembly

by Logan C., Verified Owner from MI, United States Written on April 9, 2024
Magpul has updated their description to include that this handguard does NOT fit triangular front A2 sight assemblies. Only the round ones. It is clear on their website but I can’t find that information on the Optics Planet website. All that to say, it doesn’t fit my BCM upper. So I’m going to try to return it.
Pros:
  • Sturdy construction
Cons:
  • not compatible with triangular A2 ring
Would recommend: No

Disappointed

by Pullrack, Verified Owner from MO, United States Written on July 26, 2023
Having never seen any of these MOE SL handguards in person, and in use, I took the leap and bought a set. (1) Cannot use these with a military sling mount on an Front Sight Base. (2) If you want to use the bayonet lug,,,forget that, you cant with the SL handguard. (3) Triangular handguard caps and these handguards are not fit friendly

fits a M&P-10 with factory gas block

by Chris Quarles, Verified Owner from GA, United States Written on July 14, 2023
Follow installation instructions. The installation will be super easy. This will fit a M&P-10 with factory gas block. It is a much more clean appearance than factory. This gives you more options to install accessories for low profile look.
Pros:
  • Looks great & works well,easy install
Cons:
  • None
Would recommend: Yes

magpul slimline hand guard.

by ml, Verified Owner from CA, United States Written on December 23, 2022
T purchased the mid length version and mounted it on to a 16” pencil profile barrel. Looks great with an A2 front sight. It’s very lightweight but still is noticeably durable. Can’t go wrong with magpul! Can’t beat the price either…
Pros:
  • Cost & availability
Cons:
  • None

Magpul Handguard

by Jeff, Verified Owner from NJ, United States Written on December 27, 2020
I have several of these magpul handguards in different colors for several of my builds. They have an aluminum heat shield inside. They fit well and are easy to install as long as you pick the right length according to your gas system and purchase the delta ring and hand guard cap for those who are unfamiliar with this setup. The m-lok holes are great for your accessories but beware when you tighten them down you will flair the plastic opening slightly which makes it a little harder to remove the m-lok accessory but not a big deal. Gives your rifle a modern look.

The Magpul SL Mid-Length AR/M4 Handguard will fit Mid-length AR with triangle cap!

by Michael, Verified Owner from FL, United States Written on December 5, 2020
To all of those shooters out there whishing to install a magpul SL handguard on their mid-length rifle, it can be done! As always, the manufacturers dissuade anyone from modifying their products but this application provides for two options. One must either purchase a round cap for their mid-length rifle and have the skills and punch set to remove the A2 gas block and front sight. Then remove the triangle cap and reinstall a new round cap followed by gas block and sight. All of the pinning must be basically perfect and straight. This is not complicated for the shooter that is handy with tools and used to performing more than the standard field strip. Perhaps if one is regularly building AR and AK rifles, this will be easy. However, I took a different approach even though I am used to taking a vile and/or Dremel tool to basically any gun if it will make it better or teach me something. I took my Bushmaster Mid-length rifle (my favorite) which was factory equipped with a Magpul MOE Mid-length handguard. This rifle is excellent and eats whatever ammo you chamber. However, it lacked front handguard real-estate in my opinion. I wanted to change it for years and almost did in 2016 when many blogs and discussions claimed that the triangle cap was incompatible with mid-length rifles. I finally realized that this could not be too hard and decided to put my skills to work and challenged myself to purchase the Magpul SL Mid-Length front handguard for my triangle capped Mid-l...
