Description

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:

The jig is solid in a vice. The process is easy and the end product works great.
Caleb Smith –
I have not had a chance to cut one put yet, but the jig is very solid and the lower is very secure when you put it in the jig.
Elbert Chambers –
Easy to do and plan to do more
Adrian Christen –
Good quality jig. Came with all hardware nicely packaged. Good coating on material. Fits lowers perfectly. Easy to use would buy again and highly recommend.

This is my first jig, first build/s so I can’t compare this jig to another. But so far I’ve used it on an AR15 and AR10/DPMS.308. It worked well. Can’t wait to try it on an AR9 lower. Plates are self explanatory. Everything held tight. Any issues where operator error due to not knowing what the F*** I was doing. (I have no machining experience what so ever.) Over all I would purchase this set again.

This jig is great, top notch and elite, you can do a 1000+ with this jig. The endmills are good quality as long as you use the right speed and feed rates these will do 1000+ jobs, the 2 drills are not that great but they would do the job, but not something I would use. I used some cobalt drill bits instead that I had already, if you don’t have cobalt drill bits, you can buy the 2 for about 20 bucks, they will do 1000+ parts. I don’t use a router or drill press, I use a bridgeport mill and the parts come out like a factory 100% lower finish would look like, first time quality. Get one, you’ll love it, well worth the $$$
