Overview
The Lantac SF 15 AR Lower is a stripped lower receiver designed for the AR-15 platform, featuring a durable black hardcoat anodized finish. This forged lower is crafted to accommodate standard trigger pins with a diameter of .154 inches, ensuring compatibility with a wide range of components. Commonly found in builds utilizing a mid-length gas system and chambered in 5.56 NATO, this lower provides a solid foundation for a reliable and versatile rifle.
Builds with this lower receiver are split between .223 Wylde (43%) and 5.56 NATO (43%), split between mid-length (50%) and carbine-length (38%) gas systems, and nearly all AR-15.
It was out of stock everywhere we track for all of August 2026, and today none of the 2 retailers we track has it in stock right now. Listed prices start at $189.99 at BattleHawk Armory for when it comes back.
