Great option for drill press owners

By: Wellarmedlamb on 08/03/2015 03:13:54 PM

Love this product. Less than an hour on the drill press and started during my lpk. Totally assembled lower in 3 hours. This was my first lower build. Great kit. If you screw it up polymer80 will send you one at 1/2 msrp. Great manufacturer. Address armor is lower priced so buy it here. Thanks guys.

First Polymer Mill

By: Nate on 07/28/2015 05:02:05 PM

So this was my second build, my first one was a aluminum. I like the kit that came with the G150 P2, very nice having the bits and end mill. Having the end mill marked for depth was a plus. You do have to go pass mark little bit though to get the 1.25 depth. The only major complaint I have is that front and back take down pin holes to not quite line up. I had to do a little filing.

Mill first then drill the side holes.

By: dannyo66 on 07/09/2015 08:48:48 PM

Ok. I ruined my lower. (completely my fault). I drilled the side holes first, the trigger, hammer and safety holes before I milled out the inside of the receiver. After I drilled the holes and milled out the receiver, I used a wood chisel to smooth the sides, which did work to take the rough edges out, up until I managed to catch one of the trigger pin holes with the edge of the chisel and broke a chunk of plastic out of the inside, and ruined the pin hole. Oh well, live and learn. I got the unit on sale so I wasn't too upset. Just learn from my mistake everyone. Mill the inside out first, smooth out the rough edges, THEN DRILL THE PIN AND SAFETY HOLES!!!!

Cheap Part

By: BryGuy on 05/29/2015 06:07:59 PM

Cross drilling for trigger/hammer pins and selector is straight forward. Milling instructions are sketchy. ANY goof on the trigger pin will render the safety useless. I would not recommend this receiver for an AR that you plan on using for more than a range queen.

Can't believe I waited.

By: F.Stein on 03/14/2015 10:39:13 AM

Bought this for my first AR build. I love it! Took about a hour to machine. I ordered a vice from amazon and used harbor freight drill press. My PSA lower parts kit dropped right in and matched up great to the PSA upper. I've only put 100rds though it but operations are perfect at this point. Polymer is the way to go.

Polymer 80 lower

By: Farmerbrown32 on 12/15/2014 11:00:51 AM

This thing is awesome! Took only about an hour to mill out and this is the first one i have ever done! Its fit and finish are very nice. Used a harbour freight drill press and xy vise and it was very simple to do. If you are on the fence about buying one and milling it out, DONT BE! It is super easy! I built a upper with a billet receiver, 24" lilja barrel with a wilson adjustable gas block and 15" handgaurd. It is a tack driving machine and is just as nice as any serialized lower! Thanks ares!

Ok I guess

By: SgtSlaughter on 12/01/2014 11:17:40 PM

The best part of it is that it comes with the jig. I took it to the range and test fired it fine. Took it home and put my rifle away, came back a few days later and went to pick it up and bam! The pistol grip broke off. The entire "no thread design" Is a piece of junk, the entire area around the nut is poorly designed with a pocket of meat that isnt even there, decreasing its strength by far. It also has been torture tested by many on youtube yet the trigger pin area just snapped and Im now stuck with 3 pieces of the lower. It works great if yoy need a temporary fix like to horde off zombies for a few minutes whole a buddy completes an aluminium 80...

polymer 80

By: cannoneer on 09/25/2014 08:14:45 AM

I was very skeptical at first but decided to try one anyway. I likely would not want to attempt to finish one without a milling machine but mine came out far better than I expected. Except for the grip screw being a quarter of an inch too short and the pin/screw setup for the bolt release not being exactly optimal everything fit very well. It operates as well as any other. I am quite pleased with the results.

AR15 Polymer80 receiver kit

By: Randy on 08/17/2014 07:45:54 AM

This is my first attempt at an 80% lower. On a whole it went off without a hitch. A couple of things I did that helped me with the final fitting. 1, I did not use a dremel, I used a paint stick with some sand paper glued to it to smooth the inside of the fire group area. I feel I had a lot more control doing it by hand than trying to control a dremel to the tolerances I was looking for. 2, I also used a 1/4 in wood chisel to take some of the ruff out of the bottom of the milled areas and to smooth down the sides of the milled area. The chisel needs to be very sharp and then the polymer cuts just like hard wood. It is also the only way I could figure to smooth the bottom area. I do like the two mods that were made to the receiver from mil-spec, the bolt stop pin held with a set screw and the nut and bolt for the grip are way better than mil-spec. I will be back to get another of these as soon. The next one will be a light pistol.

Amazing Customer Service at Polymer 80

By: Tom on 08/12/2014 03:25:25 PM

I finished my first 80% lower (one of these Polymer 80 kits) with a drill press and a dremel tool (with a sanding wheel attachment). The instructions were very clear and they do supply everything you need as far as bits and the jig. I added a standard parts kit (but swapped the hammer and trigger pins for captive ones) and a buffer tube and stock. To the now-complete lower, I mounted my Ares Harp upper and headed to the range. The first thing I noticed at the range was that there is a little play in the mounting of the bolt stop lever. I think that this can be fixed with a shim, but it prevents me from releasing the bolt carrier when a magazine is in place. Actuating the charging lever overcomes this issue. After about 50 rounds I ran into another issue. The buffer retainer pin came out of its mounting area because the wall on the trigger-group side of that area gave way a little. Here is where the amazing Customer Service came in. I contacted the nice people at Polymer 80 and explained what had happened (and included a photo by e-mail). My big question was "Is it safe to operate the rifle without the buffer retainer pin and spring?" The answer was yes - I just need to be careful when taking the upper off as the buffer will not be held in place. However, they said that they have not seen a failure like this before and had to make it right for me and they sent me a complete new kit to replace the one that had the issue. I told them that if the rifle would work without the pin, I would be OK but they insisted on making it right by sending me a replacement kit. That kit arrived today (only 3 days after the failure and my contacting them). Not only is the 80% lower relatively easy to finish and a good value, but the manufacturer has amazing Customer Service and proudly stands behind their product.

80% polymer lower kit

By: Andy on 07/04/2014 02:24:31 PM

I watched a number of videos on this particular kit, the G150, ordered one and received it in 2 days! It was shipped from about 40 miles from me... I tinkered with it for a bit then in under 3 hours had it completed. Everything fit like it should so I fit it to a complete upper and put around 250 rounds through it. Took it all apart to check it out, nothing slipped or fell out, worked perfectly. Now I am back for more...

Awesome Kit

By: Chad on 06/21/2014 02:15:57 PM

I was able to produce my lower in the course of a few hours of an evening. I literally only needed the contents of this kit, a drill press and basic vice I already had. I didn't even need to use a dremel tool, file or any other cutting tool to achieve the desired results. If you follow the instructions, verify your steps and measurements, you will certainly succeed in building a fully functional polymer lower. I found that doing several plunge cuts with the end mill across the entire area to be milled out makes the work a lot easier to clean out afterwards and a nice smooth surface. I was able to guide the mill by moving the basic vice with my left hand while my right held down the drill press chuck lever. I am amazed with the results and if I had to do it all over again, I'm sure it would be even easier with the experience I gained completing this lower. This is a terrific buy!
