No, TCM Stock specializes in selling parts and accessories. However, you can use our serialized parts to build a firearm, provided you comply with all legal requirements.

Check the manufacturer’s specifications and compatibility details for each part. If you’re unsure, contact TCM Stock at contact@tcmstock.com, and our experts will guide you to ensure the parts work together seamlessly.

Firearm compatibility can be complex. Even within the same make and model, there are often multiple generations, revisions, caliber variations, and factory updates that affect fitment. In addition, many firearms have been modified over time with aftermarket components, custom machining, or non-OEM parts that may change tolerances, dimensions, and overall function.

Because of the wide range of configurations and modifications in the firearms world, we cannot guarantee cross-compatibility between parts unless they are confirmed by the original manufacturer as compatible for your exact model and generation.

All parts are purchased and installed at the buyer’s discretion. Any installation, modification, or firing of a firearm using purchased components is done entirely at your own risk. TCM Stock assumes no liability for damage, malfunction, injury, or improper function resulting from custom builds, mixed components, aftermarket configurations, or non-factory setups.

Due to the highly customized nature of many firearms, we cannot accept returns or exchanges based on compatibility issues arising from custom configurations, mixed-generation components, or aftermarket modifications that did not function as intended. It is the customer’s responsibility to verify proper fitment and compatibility prior to installation and use.

In addition to reviewing manufacturer specifications, firearm-specific forums and enthusiast communities can be excellent resources. Experienced owners often share detailed build information, compatibility insights, and real-world feedback that may help you better understand how certain parts function together in specific configurations.
