Build your rifle from a strong foundation! Boasting aesthetics, performance, and practical features, the OTR-15 receiver set is the start to your dream rifle. Hours of meticulous design, engineering, and testing went into crafting the OTR-15 Lower Receiver so it would live up to the expected ODIN Works quality and performance. What you should expect to feel when you get your OTR-15 Receiver Set is outstanding ergonomics, precise tolerances, and a refinement that is still durable.

The OTR-15 lower is machined in house from billet 7075 aluminum with features and style in mind. Machined to match the ODIN Works billet upper, the OTR-15 Receiver Set provides a best in class chassis. The Billet Upper Receiver has a sleek design “No Forward Assist” and low profile brass deflector. The OTR-15 Receiver Set guarantees you'll stand out in a crowd and above all else, gives you the top shooting performance that you require.


You may notice a slight color variation between our colored anodized forends and receivers. This is partly due to the difference in their alloy types, namely 6061 and 7075. Despite our efforts to reduce color variation with the help of our anodizing partner, it cannot be entirely eliminated as it is a natural outcome of the anodizing process. While we strive to keep the color as consistent as possible, there may still be slight differences in color between individual products. For additional information on colored anodizing, visit the
Additional Support section on our website.
