• What we do personally to eliminate bubbles - start with the resin/mold at 70-75F.
• Mix the color into part B and then wait for the bubbles to degas/exit part b (typically 15 minutes)
• Start the timer and mix the two parts together and then after 60 seconds pour the mix into a new cup (eliminates unmixed resin)
• Pour the mix slowly into the mold.....usually the mold is full by the 3:00 mark.
• Tap (with a screwdriver near the middle of the mold) and move the mold around.
• Continue to perform this movement scraping off bubbles as they get into the vent.
• Wait as long as possible to insert the plug.
• Watch the resin in the cup and insert the plug, when it will barely pour and starts to tack.
• If you start with 70-75F resin you should be able to wait until 8:30-9:00 from the start of the timer before inserting the plug.
• White Plastic is Freedom
After trying to mold 3 lowers we finally got 2 useable molds. First and second molds set up too fast. Our first mold, where we warmed up the 2nd part of the polymer, set up after we were half done with the pour. Second pour (didn't heat the part 2 as much) did the same after we were almost done with pour. Our third pour we did at room temp and finally got a complete lower but the buffer tube support/brace showed through the buffer support tube and we didn't like the cosmetics of that. Finally we poured a lower without the buffer tube support/brace and got a good, useable lower. Be aware that if you are going to use the support/brace it is extremely difficult to bend into the correct shape. Wish it were pre-bent !! It will also (because the "shoulders" are thick) show through the mold (we found no way to correct this in the bending of the brace). Using a Dremel to grind down the "shoulders" would work but then the brace would be less strong, defeating it's purpose. After looking at the "torture" tests on line we decided the buffer tube support/brace was unnecessary and that it was , as my brother put it, a solution in search of a problem.
Overall we thought the mold process was simple (after NOT using the buffer tube support) and didn't take too long to produce a useable mold. Having two people to cast the lowers was helpful and probably a must. Also we used a hand sander (with the sand paper removed) to vibrate the mold as we poured to release air bubbles and the final two casts were perfect. Get this kit, follow the instructional videos, and you won't be disappointed!!
Colors are necessary if you don't want a white lower.
Can't imagine all the engineering that went into this kit but thanks for all of it!!

I am a natural skeptic. The Firearm News article on this process well researched and written. I figured it was worth the investment if for nothing more than the education. The mold quality and execution is exceptional. It is a difficult concept to get everything to pour in AND then actually pop out when cured. This mold is well thought out and the process works. I am a working stiff with more money than time so I have just sent another complete mold "kit" to a retired tinkerer gun nut friend of mine who has little money but lots of time. As such, between the two of us this process shall be well thrashed out and I shall write of the results later. American ingenuity as its finest. Get as many of these kits out there into the hands of the real people of this great nation before it is too late. Ross on Jul 22nd 2016
poured my first unit yesterday, came out great! great service and wonderful to talk with !! william t. on Jun 27th 2016
received my kit within 2 weeks, watched the how to do it on utube several times then cast one lower receiver first day following instruction made a nice lower received no visible bubbles. only thing I should have educated myself better on the color mix ratio. after reviewing that my second and third cast was also excellent and easy to do. ordered more color to try different colors. also working in industrial molding I am able to use mold release products for my pins instead of car wax. this is readily available online CRC products.

While there is a bit of a learning curve to this kit, it's worth the investment. Watch all of the videos (and I do mean all of them) before your first pour. I discovered that the tip on waxing parts made the difference between a successful pour and demold, and a cracked lower. Building an AR is a fun and rewarding experience, and doing it with a lower you cast yourself is even better. This mold kit is a great idea and a great product. I had some issues early on, but the excellent customer service these folks provide helped me work through them and got me to making perfect pours every time.
Thanks for a great product. Paddy O'furniture on Apr 12th 2016
I ordered the AR15 Mold kit with black dye. During the first weekend I ended up making 3 lowers. The first lower took a while to make because I didn't want to screw it up so I watched the great How-To videos and the "Tips" video (a must to watch) and put it together step by step with the videos. The second and third molds I did from memory and they went great. I did have a sort of a hick up with my second one because the resin set too fast so I wasn't able to fill the mold. The only part that didn't get the full resin was the buffer tube threads. I figured I'd just chock it up to inexperience. Then I realized that all I had to do was use my Dremel and cut off the back portion behind the trigger block, reinsert it into the mold and mix up a small portion of the resin. After doing this I was able to save my lower and it doesn't even look like I had to redo a portion. I elected to put a bunch of fiberglass in the molds before I added the resin. I figure that I might as well make it very strong. The Videos are fantastic and very helpful. The parts in the mold kit fit great and the finished product accepted all of my lower build kit parts. The kit is more than worth it for the unlimited possibilities it affords. Thanks for designing this mold so precisely and for the great step-by-step instructions in the videos.

This mold kit is Super, and so are the folks at AR15MOLD.com.
Excellent service, immediate help, assistance, and resolution. I really do recommend these folks to anyone building a project. Unknown on Apr 9th 2016
The first one I made was user error in the bolt catch area. The second and third I made I was careful and easily took pin out but there was still damage to the area around pin. I'm not sure what I'm doing wrong. Recievers so close to being perfect . Unknown on Apr 2nd 2016
There is a bit of a learning curve with making these (be sure to watch the videos), but all in all the product works great. Biggest thing I found was be sure rock the mold back and forth, working the air bubbles out and be sure you have resin overflowing out of the buffer tube thread area by the end of your pour. My first couple had air bubbles/no resin at the top of the buffer tube thread. Also be sure to wax the pins with car wax. I had a pin get stuck in one of my pours. I've been cleaning them with 1000 grit sandpaper between each pour and putting car wax back on to ensure they remove easily. I will definitely be ordering more resin. Unknown on Apr 2nd 2016
