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.

Does not work with triangle end caps. Period.

Works only on Round END CAPS! Great handguard

Slim and sleek, works only on round handguards, Mlok compatible, you can modify these to work with a triangle handguard, but little material is left and I would not trust to to hold up to any abuse after modification, allows you to get that extra inch forward on your grip.

Slick, Functional Hand Guard

I installed this hand guard on my friend’s AR with a standard A2 hand guard. Once I removed the A2, I realized the rifle had a triangular hand guard end cap; whereas, the Magpul SL requires a circular end cap. If this is your situation, be prepared to purchase a tapered punch from Brownell’s to be able to remove the FSB. Standard punches will not work. Even then, I had to use a finishing hammer to generate the power to remove the FSB detents. This also required removing the muzzle along with the FSB and the the sling loop on the FSB. I actually had to Dremel off the detent of the sling loop. Moral of the story, if your rifle features a triangular hand guard end cap, count the cost before purchasing this hand guard. However, in my opinion, the hard work was totally worth it. The rifle looks noticeably better and features all of the benefits that come with a slim hand guard with multiple mlok points.
