Description
Upgrade or Start Your Next Build with our Newest Billet Upper and Pro Quad Rail Handguard Combo
The AT3™ Pro Quad Rail, like the SPEAR, is designed for use with our matching Billet Upper Receiver as well as the majority of mil-spec AR-15 uppers on the market. The quad rail is the gold standard of a secure accessory mounting and that’s what we offer with this AT3 Pro Quad Rail and Billet Upper Combo. It uses the same simple installation as our SPEAR M-LOK handguard, lightened up and improved for maximum comfort, and works perfectly with Mil-spec AR-15 builds to match the sleek contours.
Improved Design and Easy Installation
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.
