    Default 80 percent arms Easy Jig Gen 2

    So I finally finished completing my first lower using the 80% arms jig Easy Jig Gen 2 that I got for Christmas, and I wanted to do a review. Here are my experiences in case anybody is looking into this product...

    Upon opening the package, I immediately noticed that there was a defect. In one of the main holes that was drilled in the side wall to attach to the main plate, there was a bunch of extra metal inside the tapped area, making it impossible to thread the bolts into the wall. After reading the reviews about how awesome this product was, I was more than a little disappointed to find this. I am not sure how this major defect, or at least a very noticeable defect, could have been less than an inch from the “inspected by” sticker, and been missed.

    See Pic .

    I called the customer service number and explained my situation. I was told that they would send out the replacement immediately, and if I did the same with the defective one, the parts would “meet in the air”. That did not happen. I waited almost two weeks before I called back, and left a message. Shortly after leaving the message, I received an email that my part had been shipped. In short, they forgot about me.

    After receiving the new wall, I was good to go. Everything else from there on out went easy as planned. I did need to order the large router plate since the router I had borrowed from my father-in-law was not one of those compact jobbies. I would recommend that you do research on your router before ordering your jig, so you can save yourself the shipping if you need to order the larger router plate.

    I also ended up ordering a pair of the hand drill stabilizers. This product works great, but I cannot figure out for the life of me why they are sold in pairs. You can only drill one side the time, and the way that I had it in the vise, you could have attached both at the same time even if you wanted to. I guess I will try to sell the match. Same advice for the stabilizers. If you are going to use a hand drill, you should probably order the stabilizer(s) when you order the jig just to save yourself the additional shipping cost.

    After that, it was all just about following the directions. I have little to no mechanical ability, and I produced a nice lower using this jig. It is easy to use, the instructions are great, and there are additional videos and references available online if you look. This is a solid jig, and once all the holes were drilled and tapped correctly, everything went together with precision. I opted to purchase the end mill from 80% arms, but used my own drill bits. I did snap the smallest drill bit in half, but that was just because I put too much pressure on it. After replacing it, I had no more issues. It does take a while to drill the main pilot hole. It is a large diameter, and gets pretty hot. I made sure to use spray lube, and cleaned out the shavings often with the shop vac and a can of compressed air.

    This was my first experience with a router, so I don’t really have anything to compare the end mill’s performance to, but I did research the prices of similar ones online, and the one from 80% arms seemed to be comparable, so I just went with it. As long as I went slow (as the instructions say) everything was fine. I found myself rushing through a couple of passes, and dealt with more chatter and vibration that I would have liked. I don’t think it affected the end result of the product, but probably put unneeded wear on the end mill. I included some pics of the process. I panicked a little bit when I saw a tiny hole start to appear during the milling process. After a couple more passes though I realized it was just the pistol grip hole. In the pictures, it looks like the finish inside the lower has a rough surface. Running your fingers over it, however, it is smooth as silk. It may just be the way the light is hitting tiny imperfections or changes in the depth. I had no issues with the fitting of the LPK. I did have a bad selector switch, but the LPK was not from 80 percent arms, and I had to deal with the other company to get that straight. There are videos out there of people turning out lowers in 45 minutes or so, but the that was not my experience. I worked on it for a little bit here and there, but I would guess total time was several hours.

    One thing I will say, is this process makes a heck of a mess. Don’t think you’ll be able to keep this process confined to a corner of the room that you would like to keep clean. I had metal shavings within about a 10 foot radius of the vise. The shop vac helps to clean up a lot of it, but expect a garage or workshop full of metal. Bottom line is that if I can do this, anyone can do this. Overall experience with the jig is awesome. I’d recommend it to anyone looking to make their own functioning lowers from 80% lowers. I plan on using it to do an AR-9 lower for my next project.

    Nice job but I see where you left out milling the rear shelf and partition. Some upper assy's may require that.

    Using a woodworking router to mill an 80% receiver is like using a screwdriver to drive a nail.

    Perhaps, but for those who want to do a 80% lower and don’t have a milling machine in their garage, this is a great way to get a great sense or accomplishment.

    Thank you, Stamps6.

    Exactly. It actually worked great, and I found it to be enjoyable as well. I will be doing more in the same way.

    There is a group of guys that hang out at my LGS. They have each built 4-5 80% guns and after trial and error using everything from a drill press and even setting up a milling machine they have found that using a router works the easiest and fastest to mill out a lower. They do about a 1/8" at a time with the end mill bit lowering it a little after each pass, The milling machine obviously does the best job but time consuming setting up. They all swear by the router but you need a quality plunge router like a porter cable, some knock off brand from harbor freight probably wont work so well.

    You do need to be careful about the equipment you use. I've looked into unfinished lowers myself. As I understand the laws, the person who's tools are used to finish the lower is the person the lower belongs to. Since you used your father-in-law's router, he has partial ownership of the lower. Gifting lowers follows the same laws as gifting other firearms. So it is doable. Just so you are aware.

    Suppose you don't ask why he wants to borrow the tool? and he doesn't tell you? will you guilty of a crime? No way to tell if you don't know.

    With the ATF they do not care about ignorance of the laws. The loop-hole to using other's tools is gifting, subject to federal and state laws.

    There can not be ignorance of the law if you were not told he was building a gun.

    Same as you lending your car to a friend and he robs a bank without you knowing. I think what you are trying to say is INTENT.
