Elite Builder 80% Lower Jig with Tooling - AR-10/.308



The .308 AR is one of the most capable and accurate weapon platforms on the market. If you’re building your own AR-10-type rifle from scratch, you need a jig that’s just as accurate. Elite Builder took their precision AR-15 jig and re-tooled it to accept DPMS-patterned LR-308 80% lowers. This jig is capable of machining any .308 receiver with accuracy as tight as one-thousandth (0.001”) of an inch.

Quality HSS-Tungsten Bits Included

The jig’s just half the equation. To ensure that level of accuracy with your build, you need the right bits and tooling. Elite Builder includes quality HSS bits, reinforced with tungsten. These ultra-hard bits excel at cutting and drilling billet or forged aluminum - exactly what you need for your 80% lower.
