Gun Nut

Very Easy

The drilling and routing went very well. The jig tools are very easy to work with and the instructions are easy to follow. Took about 2 hours to have a usable receiver. I did hit one snag with the safety detent, seems there was a small bit of metal in the drilled hole for the detent but was able to correct it with a small needle nose file. All and all very pleased with the outcome.


NON Heavy Duty Easy Jig

Item says it's the heavy duty easy jig, which it's not, it's the basic easy jig without the upgraded selves in the side plates, should have sent it back but I waited 3 plus weeks for my order so I did not want to wait any longer, everything else is like it should be, the 80% lower is good quality and the bits are good quality, just a little upset that the easy jig wasn't the heavy duty like it says that's why the 3 stars , with order next time from or

ar maker

easier than i thought

the product is 5 star. the directions were easy to follow. the you tube videos also helped. I took my time and I had the receiver milled and ready for parts in 4 hours. the rifle works flawlessly today. thanks

Not the best and not worth the money

I bought the full package the lower receive, jig, and drill bits. It took well over the expected time to Arrive, but this is because the machine that makes the jig wasn't working for a period of time. But when it arrived At first glance everything looked pretty good. I immediately started the drilling process and although it was tough to drill, it wasn't so bad. However after the first few holes,I could tell that the holes in the jig were getting warped. So much so that I most likely would never be able to use it again. This is because the jig also seems to be made out of aluminum. The only good thing is that the drill bits are actually pretty good. Not the best, but definitely not cheap. After I drilled everything, I used a router that went smooth enough. Iv never used a router on metal before but it was pretty fun. And after that I finished up with the trigger hole and other holes on the side like the safety and that wasn't too bad. And with a few hours of hard work and aching body, I was finaly complete. I finaly had a working lower receiver. Except it wasn't....When I mated the lower to the upper, the lower receiver was not flush with the upper. It was too far to one side. When I try putting in a magazine, it won't even secure into place because the upper receiver is blocking it from going in. So after all that I have a lower receiver that I spent hours on that won't work in either of my two uppers that I tried them on, I have a jig that I can't use because I can't drill a hole in the proper place anymore. Congrats to me. I just spend $250 on semi decent drill bits. Maybe I got a lemon, but I wouldn't do business with them again.
