80% Arms Easy Jig Review

I decided to build an AR lower from a 80% blank and chose the Easy Jig from 80% Arms. actually this is my second 80% project, the first turned out pretty well, so I was encouraged to give it another go.
I assembled the jig on the lower, very Easy as the name implies.

When I went to set-up the drill press for drilling out the fire control cavity, I discovered that my little 10" WEN wasn't going to have enough travel to do this operation without some finessing.



The easiest solution was to use a 3/4" piece of scrap wood, I lifted the jig assembly up onto the bit and let it down onto the plank to give me the extra 3/4" needed to achieve the correct depth. After that, the drilling went smoothly.





On to the router / milling operation. I decided to use a Porter Cable trim router as suggested o the EZ-jig site, because it looked like it would be easier to control than a full
sized router. All went smoothly milling out the fire control cavity until the next to the last pass, the end mill walked out a bit and I have a little unevenness in the floor. It will have no effect in function and unless I point it out no one would know. I had been checking the collet every other pass but neglected to check at the end, KEEP THE COLLET TIGHT!



Note: My first lower was done using a full size Craftsman router. It is by far easier to complete this operation with the trim router, however I think the finish was smoother with the heavier router.

Here is the finished lower, ready for assembly:



I add some photos of the finished carbine a little later.

This one (with bullet button) is getting a generic M4 style upper and adjustable stock for now. (I haven't decided weather to register it or neuter it, to comply with California's new, even stupider laws)

Well, cool!

I hope you didn't misunderstand me... I was curious if you were going to have the lower finished with anodizing or Cerakote or rattle can, etc.

I like what you have done so far.

Oh, sorry, maybe Aluma Hyde. I don't think they look all that bad bare.

edteach is on a distinguished road
I bought the easy jig. It was a bit more expensive then the others out there but I could tell by watching the videos it was better made and almost fool proof. I also opted for their bits as the endmill was the proper one and made it much easier to not damage the jig. I can tell you this, I have all the tools but did not have a drill press. I was on the edge of buying one but opted to try it with out. The work was work it was not fast nor hard work but it was not building a snap together model either. Took me about 2 hours from beginning to end. for one unit. Usually the first one of anything is a learning curve. The video made it so my unit as very nice when finished. It needs some aluma hyde or similar. I was going to sell the jig once I finished but its such a nice unit I think I will keep it.

Awesome guys. I just received 4 80% lowers from DaytonaTactical. Next thing is this 80percentarms easy jig. Good to see that others have been able to finish their lowers with this jig. I have never attempted one, but I am very competent with tools

Received my Easy Jig last week. Next week I'll mill my lower, basically copying edteach.
Only difference is I have a drill press but have to get the router.
I have Alumahyde on order.
