TX-Series Complete Upper Receivers

Complete upper receivers are a simple and hassle-free upgrade to an existing lower receiver set, providing better accuracy, reliability, and overall functionality. The TX4 CURs are offered in two variations, the Standard and the Duty, analogous to their full-size rifle counterparts.

If you already have parts that you’d like to have included in the upper, replacing existing components, let us know in the notes section during checkout and we’ll make the appropriate arrangements to have the price adjusted and the parts received, inspected, and installed.
