I had drafted a detailed review of my exp. with 80% Arms Easy Jig, as well as, their lower receiver. Sadly, new members have a 2000 char. limit here. With that being said, here's a summary:

Some things I was specifically interested in:
1.Easy
2.Reliable
3.Ability to complete work with only the use of simple tools. (no drill presses, mills, lathes, cnc, etc.)
4.Good instruction
5.Solid customer service.

In the end, I opted for 80% Arms.

Less than 2 days later I had an 80% Arms Easy Jig, and stripped 80% lower (non-anodized).

In my endeavors, I came across a video where this guy had completed a jig on a flimsy table w/ a drill, a POS router, and a C-clamp. His results, near perfect. To me, that was PRECISELY what I was looking for, and I found it with 80% Arms.

PROS:
1. Great Customer Service (as illustrated by their staff here on the forums). *Also, thanks Jeff!!
2. It's Easy. REALLY Easy!
3. Superb Results.
4. Good Instruction/Ref's. (eg. vid. and tech doc).

CONS:
1. Anodizing of parts was a tad sloppy (this has ZERO impact on overall quality/functionality)
2. Threads on right plate (top) not well fabricated. (still functional)

FINAL REMARKS – It's a newer company, with a fairly newer product line. With that being said, it may not contain the 'flare' of a company conditioned over a 50 year existence. Although, it's quite obvious that they believe in their product, and are COMMITTED to making the customer happy. I, as their customer, made a purchase on a faith that it would work. It worked perfectly and precisely as they advertised. I am beyond happy with 80% Arms and not only will I return, I will share my great experience with others. Thank you 80% Arms for making this build a ridiculously easy piece of cake.

Broken Armory has some really nice 80% lowers and a really nice jig, they also sell bits with theirs and one of their mill bits is custom made and cannot be found anywhere else. They also have a really good video of the whole process of milling it out, and the guy used a drill press, and c clamps.

Been looking at this. Look like a good product. May jump on it.built to last video is very good info as well.

First post eh?

Indeed it was. That makes this one, my second.

You left out the part about doing it on the kitchen table...you must be single.

Yeah, his first and second account got the banhammer a few weeks ago for shilling..

Was arms 80 threads.  However it does not quite pass the sniff test being the first post and all.

Nice to have another 80% option.

How long did it take you to router it out? They claim it takes half the time. Would you consider it something anyone could do?

seriously?

if you're serious, you really ought to get outside more often...

sniff test? wow... just wow.

thanks for the welcome to the forums Mr. Posts:3265 Team Member guy.... /facepalm


*I also have full video of me unpacking the contents, as well as, portions of the build. But I'm sure that wouldn't satisfy the weirdo's on here with nothing better to do with their lives than call out a first post as some conspiratorial shill attempt...

well... from start to finish an entire day, but only because I;

1. am fairly lazy and took a break after each hole
2. wanted to verify and re-verify instructions a billion times due to paranoia of botching the job
3. refer to 1

however, total (effort) time that I would guess was; approximately 2-3 hours. I couldn't say if the Easy Jig saves time or not because I've never tried any others.

In ref. to the question; "Would you consider it something anyone could do"? - I do. However, one must read and pay very good attention to the instructions, tips and advice very carefully. I would have to guess that most mistakes are due to lack of patience, and otherwise rushing the job.... for me, the hardest, or most challenging part was the milling for sure. That puppy is spinning at approx. 30,000 rpm with a hardened bit... eg. if it catches something, something is going for a ride. And, I did have the bit (end mill) catch on me once because it came loose on me... not fun but thankfully only resulted in some nik's on the sides.

If I were to make another, now knowing what I do, and if I had a drill press.... then it definitely would have been in the order of 1-2 hours.

LOL the irony in your comment.... because, I'm not single and I found that out that very same evening when the Mrs. hopped across the floor with a "pain" in her foot... and wouldn't you guess it, small sliver of aluminum... eek.

Dude, calm down.  Shilling is a common thing here.  It is pretty obvious when a first post is about how great a product from a new company that no one has heard of is.  People have been even so elaborate to create a second account to chime in on how great this new product from a new place is as well.

You're welcome to look at the previous thread I was referring to.

This site is a little more supported than you realize.

I'm not accusing you if shilling, I'm noting that it being the first post advocating a company that is pretty new with a new product seems a little suspicious.

Well Dude, I am quite calm. If you recall, you were the one that came to my thread and said;
"Yeah, his first and second account got the banhammer a few weeks ago for shilling..

Was arms 80 threads. However it does not quite pass the sniff test being the first post and all."

So, if you weren't accusing me of shilling, what were you trying to say? You do realize that your first comment in my thread was to accuse, and offered nothing constructive? Troll much?

Bottom line is this; I had never even heard of ar15.com, or 80% Arms prior to considering an AR build recently. The most challenging part for me was identifying a JIG best suited for my application. So much challenge, that I decided; "hey why not help others like me". Hence my review. I merely thought I would share an experience. I'm sorry that the domain admins prefer to limit new posts to 2,000 characters. Had they not, perhaps you would have seen a more clear depiction of my activity, including videos, pics, etc. Gripe with admin, not me. Go get yourself some fresh air, Dude. It will all be ok. No grand conspiracy to shill here. /facepalm wow.

Thanks for the review.  I know that 80% Arms has released a universal jig recently and I'm planning on getting that setup to do some 80% lowers.  Have you assembled your lower with the LPK yet?  Wasn't sure if the pic of the rifle was before or after completion.  Did you get the complete jig and their bits & end mill kit?  From the sounds of it you'd recommend using this jig for others, am I correct?

So..... how would you run some sort of coolant to the setup? I would suspect the end mill gets rather hot, running it at the speed (rpm) a typical router spins, 15 or 20 K RPM?  Most end mills run in the 1 to 2 K RPM range, and still use coolant of some sort. Did you clamp your jig to the table first? Just wondering, BTW.

No problem. Glad you liked. The jig that I got is the Easy Jig, and at the time that I purchased it, it was not being advertised to be compatible with other's lowers. However, it's been said that it will still work with certain lowers. However, some minor modification to the jig may be needed. I found a decent chart at Comparison Chart which lists some useful information regarding lowers and this jig.

edit - I did get the end mill from them as well.

I did assemble the LPK which I purchased from 80% Arms. It's a standard CMMG kit with the color coded bags. I watched CMMG's installation video which was SUPERB. Entirely TOO easy. And, the kit so far seems great.

If I had to make a recommendation to you right now, it would be using 80% Arms Jig and their lower. However, (and I knew this shit would happen), it's only been a few days and I'm already getting an itch to build another. I myself may very well try a different lower just to save some bucks, and determine compatibility with this Jig. From what I understand, the minor modification to the jig that is needed, is childs play compared to actually completing a stripped lower from scratch. So, we'll see. Again, if you're looking for no-nonsense get 'er done parts, just get the jig and lower from 80% Arms and be done with it.

My coolant came in the form of a big ol' can of WD40 (and that little red spray straw was VERY DAMN HANDY). I found myself using more on drilling than milling. I made shallower cuts (per pass) than what the instructions told me to, just to be safe. Interestingly, the end mill barely got warm as I touched the tip after nearly each pass just to see.

I absolutely clamped the jig to the table first. This is a necessity.

p.s. I forgot that the only tool I used which I don't think was listed, was a digital caliper. Even though the depth gauge grooves on the jig were SPOT on accurate, I wanted to double check everything. Probably not necessary but I was using those pilot tip drill bits and they can fit oddly in the depth gauge grooves (issue of the drill bit, not the jig).

I hate those new style WD cans. With my hands as they are, I have a difficult time holding them and pushing the button. I am adding a coolant setup to my machine.
