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

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.

Solid and Secure Mounting

• This rail is lightened down all four sides of Picatinny Rail, making it lightweight while still remaining solid for all your favorite accessories
• 5 Integrated non-rotating QD Sockets for a variety of sling configurations
• Durable 6061 aircraft aluminum alloy construction – designed to take a beating
• Picatinny top rail perfectly aligns with AR-15 flat-top upper receivers, both forged and our AT3 Billet Upper
• Handguard uses screws to clamp around the barrel nut, with anti-rotation tabs and anti-slip screws that ensure a rock-solid lockup

Simple Installation

• Installs easily, just like our SPEAR M-LOK rail – you’ll only need a few simple tools to get the rail installed. Perfect for assembling a new build or upgrading an existing rifle – it’s 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, it’s easy. Check out our video below for a guide on the complete installation.

Exceptional Fit and Finish

• Durable matte-black anodized finish resists scratches and provides an attractive surface that matches the rest of your build
• Vented rails on all 4 sides reduce weight and help dissipate heat from shooting
• Scalloped rails and clean lines for a unique look that flows into the AT3 Billet Upper
• Proudly made in the USA
• Backed by the AT3 Lifetime Warranty
