Description
Now compatible with AR-10/LR-308, AR-15 and AR-9!
With its steel plates and precision machining, the Elite Builder has been a favorite among AR-15 and AR9 80% builders. Now, we’ve included new plates to fit AR-10, LR-308 and .308 80% lowers! The EB Jig can now complete virtually any receiver for the AR’s numerous calibers.
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.
Optional Rugged HSS Bits
The EB Jig can be paired with quality high-speed steel drill and end mill bits if you choose. These tough HSS bits can chew through multiple receivers for all your builds. All you need to complete your lower is a basic drill press and about two hours’ time. The tool kit includes:

- (1) 5/32 Drill Bit – 3”
- (1) 3/8 Short End Mill – 3”

Haven’t used it yet. I’ll write a review when I do. You need to include a set of step-by-step written instructions or a downloadable video on how to set it up and use it.

I liked the jig and plan on using it a lot more

Each plate is numbered to the order of drill plate ! You can’t go wrong if you follow the drill plate numbers in Order, is a lot easier if you have a drill press with calibrations, which is automatic drill . This is a precise drill kit.. The best out there! Just take your time and it will give you the perfect lower. I used it for 3- 6.5 Creedmoore lowers. Turned out perfect! Thank you for a great jig!

Haven’t gotten a chance to use it yet… Not use to a dedicated drill press jig.

I agree with another reviewer here who said it would be really nice if you guys would make a video demonstrating how to use it. Here on the site it says not to use a router but to use a drill press, but you include an end mill bit when we purchase the tooling to come with it. I can’t be the only one confused about how to use this jig correctly, and it would be nice if you guys would provide instructions, or better yet a video demonstrating its use.

THE JIG IS GREAT BUT I WAS A LITTLE DISAPOINTED WHEN I FOUND OUT IT WONT WORK WITH 5D TACTICAL’S LOWERS. I’M KEEPING THIS ONE AS I PLAN ON DOING MORE BUILDS WITH OTHER LOWERS BUT I ORDERED THE 5D TACTICAL ROUTER JIG TO DO THERE LOWER WITH. NOT A FAULT OF THIS PRODUCT I SHOULD HAVE DONE MY HOMEWORK BUT NOW I HAVE 2 REALLY NICE JIGS THAT WILL COVER PRETTY MUCH ANY LOWER OUT THERE.
