LIGHTWEIGHT AND DURABLE
Free float design enhances accuracy by keeping stress off the barrel.
Rock-solid 6061 Aircraft Aluminum handguard that withstands the toughest conditions.
Rail height perfectly matches an AR-15 flat-top upper receiver – your optics, iron sights, and other accessories will line up perfectly.
Unique low-profile design — taller than it is wide (see pictures for exact dimensions). This makes our rail extremely light and easy to grip.
Backed by the Lifetime AT3 Warranty.
IMPECCABLE FIT AND FINISH
Precision milled MIL-STD-1913 (picatinny) rails on all 4 rails. None of the sharp edges that you will find on inferior rails.
Vent holes that run alongside the gas tube keep the rail cool, even after a long day at the range.
Hardcoat anodization provides a durable surface that resists scratches and matches your existing parts. For our those with Magpul Flat Dark Earth Cerakote, the finish is even more durable.

FREQUENTLY ASKED QUESTIONS
Q: How do I know if this will fit my AR-15?
A: This will fit any AR-15 that has a standard mil spec upper receiver. It will require some modification to your firearm though, including replacing the barrel nut, removing the flash hider, and possibly adding a low profile gas block. Want to learn more? Watch the installation videos.
Q: Do I need to buy anything else?
A: For longer handguards you may need to replace the gas block or front sight with a low profile gas block, available here. These gas blocks are low enough to sit under the quad rail. You will also need to get an armorer’s wrench for the barrel nut, and we highly recommend a vise block to hold the upper receiver in place while you work on the weapon. Get armorer’s tools here.
Q: Will this work with my AR-10/.308?
A: No – these quad rails are made for standard AR-15’s. If you have a 7.62/.308 AR variant, check out our AR-10 / 7.62 / .308 page.

Love the way it looks and feels
This free floating handguard is freaking amazing but what’s makes my experience one of a kind was the assistance of Alvin from AT3. The handguard allows me to add on so many more pieces if I desire. And, it’s not bulky at all and my rifle still looks clean without being over accessorize.
Looks great on my new AR build.
Arrived quickly and packaged well. The rail is very nice in that it doesn't have the rough edges most quad rails do therefore alleviating the need to buy rail guards.
