.223 Wylde barrels are an improved throat design to the .223 / 5.56 caliber barrels but they shoot both .223 and 5.56 ammunition. It is like getting a National Match barrel

Our rifle uppers use both US Made and imported hand guards but all other parts are guaranteed US Made.

Our pistol uppers use both US Made and imported hand guards, but all other parts are guaranteed US Made.

Most importantly we use only US Made Steel Gas Blocks on any model using a low profile "micro" gas block

Texas Gun Builders' upper assemblies are available in Flat Dark Earth, Burnt Bronze, and many other Cerakote and KG GunKote Colors, and are made from the highest quality materials and with the exception of using imported hand guards on some models... every other part is Made in the USA!

These uppers are not just assembled in Texas, several of the parts are made right here in Texas and Texas Gun Builders runs our own Cerakote and KG GunKote application facility.

So with the high-quality materials, meticulous workmanship & incredible pricing you can't go wrong.

We use Anderson Manufacturing flat top M4 Mil-Spec upper receivers, forged and then CNC Machined from 7075-T6 Aluminum, providing you with the hardest and most durable material of any upper receiver!

The barrels are made from 4150 Gun Quality Parkerized Chrome-Moly Steel, Heat or 416R stainless steel and Treated to RC 28-32 Hardness, and Stress Relieved! The barrels are incredibly accurate and durable.

The gun builders at Texas Gun Builders have over 40 years combined experience, led by an ex-Army Armorer. Our uppers are torqued to military specs & quality checked continuously.

These upper assemblies are available with or without the BCG and Charging Handle and ready to drop it onto your AR-15 Lower... or have us supply the lower.

You can find lowers here.
