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.
You can also now choose to include the enhanced drill plate to further make it easier for you to drill and hollow out your fire control group pocket.
PLEASE NOTE: Tooling for this jig is optional. You'll need to select whether you would like accompanying tooling with your jig.
Quality HSS-Tungsten Bits
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 came up with a set of 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. Choose the option to add them onto your jig to ensure the most accurate milling and drilling possible. The tooling includes:
- (1) ⅜ Drill Bit - 5”
- (1) 5/32 Drill Bit - 3”
- (1) ⅜ Short End Mill - 3”
- (1) 5/16 Short End Mill - 4”
- (1) ⅜ Long End Mill - 4”
