GWOTX4 Complete Upper Receiver

Introducing the GWOTX4 Complete Upper Receiver: our no-nonsense tribute to the rifles wielded during the Global War on Terror, specifically designed as a quick and easy upgrade for any existing AR-15 pattern lower receiver.

Engineered with LSA-grade precision, this upper is built around the rugged and ultra-durable Lone Star Armory TX4 forged receiver set, delivering exceptional performance straight out of the box and eliminating the need for tedious modifications.

The quad-rail upper is all about simplicity and effectiveness, just like those standard-issue weapons we fondly remember—only better. Ideal for new-to-intermediate users, it is meticulously crafted to surpass military specifications, boasting LSA-grade accuracy and battle-proven reliability. With blistering precision when using match-grade ammunition, the GWOTX4 CUR is rigorously tested to excel in any role, from personal and home defense to demanding tasks in law enforcement and military settings.

This plug-and-play upper has been created, tested, and fielded for end-users seeking a versatile, reliable, accurate, and hard-use turnkey solution to enhance an existing AR-15 pattern lower receiver at a cost-effective price.

GWOTX4 CURs are tuned in-factory using a Lone Star Armory TX4 test rig, and are shipped with a tune pack that includes the appropriate buffer spring and weight. Tuning results in less felt-recoil and an increase in reliability and service life.

All Lone Star Armory platforms including the GWOTX4 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.

Complete Upper Receivers are built-to-order with a 4-5 week maximum lead time from order to shipping.

The GWOTX4 Complete Upper Reciever is proudly backed and supported by LSA’s Forever Warranty.
