Texas Gun Builders uses and sells 100% Made In The USA parts for the lower receiver of your AR-15 or AR-10.

Unfortunately many Internet sites are promoting lower parts kits made in other countries that are made from sub-standard materials.

While we have very low prices on our lower receiver parts, we can't, and WON'T compete with any company selling sub-standard parts.
