If you’re planning a build without a Front Sight Base, make sure you pick up a Low Profile Gas Block with the handguard.

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. 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. That’s what we offer with the AT3 Pro Quad Rail. The quad rail is still the gold standard of secure accessory mounting, but they’re in desperate need of a reboot.
