Elite Builder 80% Lower Jig (AR-10/.308)
Price range: $149.99 through $264.99
Description
The popular, affordable Elite Builder 80% Jig has been reconfigured to serve the ever-growing .308 AR market: Re-tooled to accept the DPMS-patterned LR-308 80% lowers, the Elite Builder Jig allows any shooter to part together an accurate, custom .308 rifle from scratch without breaking the bank.
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 and Enhanced Drill Plate are optional. You’ll need to select whether you would like accompanying tooling and plate with your jig.
Quality HSS-Tungsten Bits
The jig’s just half the equation — the bits you cut and drill your receiver with matter just as much. So, Elite Builder came up with some high-quality HSS (high-speed steel) bits. These tungsten-reinforced bits provide superior accuracy and resistance against wear, allowing you to complete any forged or billet lower with confidence. Choose the option to add them onto your jig to ensure the most accurate milling and drilling possible. The tool kit includes:
- (1) 3/8 Drill Bit – 5”
- (1) 5/32 Drill Bit – 3”
- (1) 3/8 Short End Mill – 3”
- (1) 5/16 Short End Mill – 4”
- (1) 3/8 Long End Mill – 4”
Jig Features & Specs:
- Compatible with any DPMS (LR-308) 80% lower
- Self-aligning jig requires no special fitting during setup
- Black anodized finish protects against rust and corrosion
- Pre-drilled holes for hammer, trigger, and safety pin holes
- Reinforced steel template plates for completing multiple lowers
*Important – This jig was designed with a drill press in mind for completing your 80% lower and is not designed to be used with a router/laminate trimmer.

Well made, and shipped quickly. I have it in the mill right now, looking forward to using it many, many times. Thank you Gun Builders!

After a minor modification to fit the lower I had it worked pretty decent. I would recommend an additional plate to remove more material with drill bits before switching to the end mill. I did find myself removing the plates several times to clear away material that was building up in the space between the drill plate and the lower receiver. All in all it got the job done, just take the time to clear the material or run the risk of breaking a drill bit or two

Well built and good quality! From experience with other jigs it would be so much better if you add 1 more plate for 3/8 drilling to remove a little more material before milling. But still a great quality jig.

During initial fit-up, the side plates did not fully engage the front pins into the pivot holes in the receiver. The inner surface of the side plates had rectangular shaped spacers?, stand-offs?, machined into them.Height was a nominal .125”, which was the exact amount of space needed to attain proper alignment, and fit of respective side plates to receiver.Once removed, fitment was accomplished to my satisfaction. The build continues……..

Nervous at first, once I figured how to keep my Chuck from wobbling loose (super glue?) turned out great!

Good resilient design. Haven’t finished it yet. But should work out nicely.

I haven’t used it yet-I still need to purchase the oil to use with this, as well find some instructions, but when I’m excited about getting started on this.
