The Texas Custom Guns AR-15 lower receiver is built from 7075-T6 forgings. The contour
is fully machined leaving no flash marks from the forging and we take extra
care when machining our lower receivers resulting in tolerances that are
tighter and fits that are better than other lower receivers. We adhere to mil-spec
tolerances to ensure that our lower receiver remains compatible with any
quality aftermarket parts you can find. After the machining process is complete
the lowers are checked for quality and shipped off to our finishing facility
for type III hard coat anodizing.
