Questions & Answers
Will this fit an AR10? Expert Answer

No. Because of the barrel nut size difference between the AR-10 and AR-15, the handguards and rail systems are not interchangeable.

Stern Defense Handguard by Jay, August 9, 2020
Exactly as I expected, love it, was less expensive on Optics Planet vs Stern Defense website. Fit AR build fine and no modifications needed would recommend to all considering this for their next AR build

Helpful Negative Review
The handguard requires you to use it's barrel nut. So if you want to just swap out the handguard it will not fit. Especially if you are using a PSA upper. Beyond that it was a nice handguard. Too bad I have to return it

Factory box looked returned by Made it work, Verified Owner, September 6, 2025
As title says, the box this item came in was taped shut with packing tape. Later I discovered the handguard was missing screws, this was the last part I needed for my .338 ARC build, so I ordered the size screws it appeared to need, and finished th...

Stern Defense SD MOD5 M lok handguard 8” I used on pistol build. 8.5” barrel left enough room to install flash hider. I gave it 3 stars because I could not time it enough to not touch gas tube. The barrel nut is too tall which puts upper pressure on ...

Product Info for Stern Defense SD MOD5 M-Lok Handguards

The Stern Defense SD M-LOK Handguard Rail is an ultra-short and light-weight rail solution that is completely free-floating. This rail by Stern Defense utilizes M-LOK technology and features the "Insert now, Attach Later" feature. The benefits of a short rail are that you get a very slim profile and greater control of your AR based rifle. With this shorty rail you also get a very low profile and allow the barrel to extend out so that it doesn't hit rail at an uncomfortable angle. A low profile is great for a CQB scenario where you can keep you hands occupied instead of fumbling with a hot barrel or having an attachment laying around that is awkward to operate. For a great way to make sure you are working with one of the best free float forends the AR shooting industry has to offer, choose the Stern Defense SD M-LOK Handguard Rail.image
