Welcome to The NEW Texas Gun Builders

The new TexasGunBuilders.com is now completely veteran owned and managed, and a number of changes have been made.

The TexasGunBuilders.com website is now dedicated to offering Completely US-Made, AR 15 and LR 308/AR 10 upper assemblies. Not just assembled in the US, like many companies claiming US-made, but every part we use in our advertised upper assembly models is Made in the USA.

Our great selection of AR15 and LR 308/AR 10 upper assemblies are currently available only in Black. We will be offering Cerakote and KG Gun Coat coatings and colors in the near future.

We are not currently offering lower assemblies or complete rifles but may add those in the near future as well.

Thank you for your interest in our company, and if you choose us for your AR-15 components and parts supplier, whether that be our great AR-15 and LR 308/AR 10 upper assemblies or just parts and tactical accessories we'll do our best to make sure your experience with our company is second to none.

We are continually adding more products to our online site, but if you need something that you don't see, have a question that we can help with, or just need some technical advice, please don't hesitate to call or email.

TexasGunBuilders.com's customer support is always available. Our phones and email are answered by real gun builders with many years of experience. We'll make sure we can help you if you have a problem and steer you in the right direction if you just have a question.
