Designed as the ideal patrol and entry rifle, assembled to not just meet but vastly surpass mil-spec standards, the direct impingement TX4 Duty Carbine utilizes hand-selected components mated to a Lone Star Armory TX4 forged receiver set to offer end-users industry-leading performance out of the box.
The plug-and-play TX4-D Complete Upper Receiver has been created, tested, and fielded for end-users looking for a versatile, reliable, accurate, and hard-use turnkey solution to upgrade and augment an existing complete lower receiver.
Utilizing hand-selected components, the TX4-D CUR uses a forged receiver with a forward assist as a foundation for the ultimate suppressor-ready rifle upgrade package, guaranteeing match-grade accuracy and proven reliability (1 MOA or better with competent ammunition).
TX4-S CURs can be optionally tuned in-factory, and shipped with the appropriate buffer spring and weight. This option must be selected before adding the product to cart. Tuning results in less felt-recoil and an increase in reliability and service life.
All Lone Star Armory platforms including the TX4-D CUR are Berry Amendment-compliant, manufactured, and assembled entirely from American-designed and American-manufactured components in the United States for civilian, law enforcement, and military customers.
NOTE: A $60 surcharge for pinning and welding 14.5″ barrels applies.
Complete Upper Receivers are built-to-order with a 4-5 week maximum lead time from order to shipping.
The TX4-D Complete Upper Receiver is proudly backed and supported by LSA’s Forever Warranty.
