    Tips on how to make a great pour:

    • 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.

    1. great product, well made!

      poured my first unit yesterday, came out great! great service and wonderful to talk with !! on Jun 27th 2016

    2. east to use

      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. on Jun 14th 2016

    3. great customer service

      I have had questions and minor issues. All of which were solved by quick reaponses on Apr 25th 2016

    4. Worth the effort

      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.

    5. Easy to use when you follow the great How-To Videos

      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. on Apr 11th 2016

    6. This mold kit is SUPER!

      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.

    7. Bolt pin area

      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 . on Apr 2nd 2016

    8. Great Product and Fun

      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. on Apr 2nd 2016

    9. great for a back up to Aluminum

      color mixing has been fun. the ease to set up is nice. Any tips and tricks would be great.
      I have found changing out a few parts from steel to stainless steel works wounder's with your jig.Thank you for your time.

    10. Great

      I have used this for 4 lowers now. 2 of which I screwed up due to user error. It has held up nicely to some blonde mistakes lol. Customer service and response is fantastic. I would recommend this to anybody. It is quite an awesome experience.

      I think it's awesome that they shared my pictures and have been understanding of all of my questions and feedback.
