Product Info for AT3 Tactical Pro Series Free Float Quad Rail AR15 Handguards

The New and Improved Pro Quad Rail Lightweight, Rigid, and Easier to Installimage

The quad rail is still the gold standard of secure accessory mounting, but they're in desperate need of a reboot. That's what we offer with the AT3 Pro Quad Rail. It uses the same simple installation as our SPEAR M-LOK handguard, has plenty of lightening for maximum comfort, and it works with Mil-spec uppers, as well as our Billet Upper to match the sleek contours.

The Pro Series Rail comes in 7, 9, 12.5, and 15 inch lengths, making it ideal for upgrading existing guns or starting fresh with specialized AR15 builds. If you're planning a build without a Front Sight Base, make sure you pick up a Low Profile Gas Block with the handguard.

Simple Installation:

Installs easily, just like our SPEAR M-LOK rail you'll only need a few simple tools to get the rail installed. Click here to view our instructions.

Perfect for assembling a new build or upgrading an existing rifle its compatible with most mil-spec upper receivers on the market

Once you've got it installed, you'll have plenty of room for any Picatinny rail accessories like lights, foregrips, lasers, or bipods

Seriously, its easy. Check out our video below for a guide on the complete installation.
