Product description

AT3™ 300 BLK 16″ Assembled Forged Upper – 2A Basics ASAL 15″ Handguard – No BCG/Charging Handle

Built to Order – Ships Within 3 Business Days

This assembled upper delivers a full-length 300 BLK platform focused on versatility and value without breaking the bank. This is the foundation for shooters building a hunting rifle, suppressor host, or multi-purpose setup where you need the hard-hitting performance of 300 BLK with maximum velocity from a 16-inch barrel. The 15-inch 2A Basics ASAL handguard provides M-LOK mounting on all sides with a patent-pending Anti-Slip/Anti-Lift attachment system that ensures a rock-solid fit while keeping weight and cost down.

The AT3 16-inch medium profile barrel in 300 BLK features black nitride finish for durability and corrosion resistance, with a pistol-length gas system for reliable cycling with both supersonic and subsonic ammunition. The 1:7 twist rate stabilizes both light and heavy projectiles across the full range of 300 BLK loads. The 2A Basics ASAL handguard weighs just 10 ounces without mounting hardware and features M-LOK slots on all sides, anti-rotation tabs, and a shaved Picatinny top rail for weight savings while maintaining full functionality.

Built on AT3’s forged upper receiver with forward assist and dust cover installed, this setup pairs a low-profile .750 steel gas block and stainless gas tube for reliable function. The AT3 birdcage flash hider effectively reduces muzzle flash and gives the muzzle a clean, finished look.

Note: Does not include bolt carrier group or charging handle. The upper is shipped fully assembled.
