Overview
The Odin Works OTR-15 .223 Remington AR Lower is a stripped billet lower receiver designed for the AR-15 platform. It is specifically calibrated for .223 Wylde, offering builders the versatility to chamber both .223 Remington and 5.56 NATO cartridges. This lower is frequently used in builds that incorporate a rifle gas system, making it an excellent choice for precision shooting and reliable performance.
