We choose the 7075-T6 because it is one of the highest strength aluminum alloys available. Its strength-to-weight ratio is excellent and it is ideally used for highly stressed parts.
The TB .308 80% lower receiver is precision 3-D machined from billet 7075 aluminum—made in USA—to mil spec tolerances, finish options are: tumble de-burred, bead blast finished and Mil 8625 Type III, Class 2 anodized. All that is left to do is machine the fire control pocket, for the trigger group and drill a few holes. Once complete you will have a fully functional TB.308 DPMS pattern lower receiver for .308 / 7.62x51 NATO, compatible with DPMS platform upper receivers, Magpul, SR-25 & DPMS LR-308 Magazines. Includes integrated trigger guard.
- This is not a completed receiver and still requires machining to be done in order to have an operational firearm.
- NO FFL is required for purchase, item can be shipped directly to your home.
- As determined by the firearms technology branch of the ATF, this lower receiver is not classified as a “firearm” as defined by the GCA of 1968.
