• 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.

Hello everyone i just want to say this product works well it will
easily produce ar lower that rival any other polymer lower out their
However i do believe you could have made the buffer area
Slightly larger to accommodate your stainless brace so i kinda redesigned the brace and all your pins (copper plated welding rod really ? stick with the stainless ) the brace dug into the delrin rear takedown pin on my first pour it didnt want to come out of the lower it did with a drill glad i mesured evey thing before i poured
a stainless replacement fixed that
once i get the castle nuts i oreded i plane to photo my new brace i will return to post them
mine brace will have steel threads Unknown on Dec 15th 2016
PRO: The instructions are clear enough.
Dropped a completed rifle twice and had no affect on mold
CON: The only drawback are some small bubbles that where on the surface on the very upper part of mold.
Overall this must be the toughest mold out there with the brackets and the thickness of the neck and take-down pinholes. Jerry on Dec 5th 2016
Good product, molded with no issues other than the tan is more of a cream color than tan. Unknown on Oct 13th 2016
Having purchased this kit back in May 2016, I have since poured four solid lower receivers using this mold kit. The kit provides you with enough resin to pour five (5) lowers; with a bit extra to pour a sixth, and even possibly a seventh lower. Nice!!
As others have stated, follow the provided instructions carefully. Read it first, watch the videos, and take advantage of various tips 'n tricks provided by the makers of this kit and customers. My *very first* pour was ruined due to the buffer detent pin becoming stuck in the hardened mold. With no way to remove it as hard as I tried with my locking pliers, I was forced to destroy the lower receiver with a dremel tool to reclaim the pin.
Upon closer inspection, I noticed that a lot of resin had seeped its way down the hole of the buffer tube mold/screw part in which the detent pin is inserted. As the resin hardens, it expands within this hole, thereby lodging the buffer detent pin extremely tightly in the hole. It has since happened to me a second time, again with the destruction of a lower receiver to retrieve the pin. My remedy to this was to apply a very, very light bit of clear silicone around the area(s) where the buffer detent pin enters and exits the buffer tube mold/screw part. Doing this in no way affected the threads of the receiver's buffer tube in the finished product. It kept the resin from seeping into the hole and lodging the detent pin, making for a much easier time when grabbing and twisting the pin out with my locking pliers (don't forget to apply a coat of non-silicone car wax to all metal parts, as well as taking note of which end of the detent pin you install prior to each pour. The end that you grab with your locking pliers always points UP out of the mold!!).
Each pour is a new learning experience for the next. Take it step by step, keep a sharp eye on the time of each step, and do not let your mold sit longer than 70 minutes for disassemble. The longer it sits, the more difficult each mold part will be to remove as the resin hardens.
When all was said and done, I had four great lowers out of six pours (two boo-boo's on my part). I have assembled one of my lowers to a Delton .556 M4 carbine upper with a little modifications to the lower to assure a perfect fit (tiny bit of dremel filing along the rear buffer tube area). It has since been to the range and fired off approximately 1,200+ rounds without a hitch. Various 30-round magazines used all fit and fed properly with the lower (Magpul mags, RJF mags, Tapco plastic mags, and original Colt GI mags). 1,200+ rounds later and the lower receiver still looks extremely solid with no cracks or warping. Sure, it's not "mil-spec", but hey... it still holds its own when compared to aluminum receivers made by other big name manufacturers. AR15Mold.com is a true underdog in the lower receiver market!

Although the process was taxing at times, In the end I managed 6 pours and 4 usable lowers. I lost one while demolding and one during the pour when the batch set too quickly. I found the most frustrating part was bending the brace, which while I feel it does strength the overall end product. In the future I feel like one improvement that could be made is including diagrams or perhaps even prebending the brace. Overall I am satisfied with my end product and would purchase it again if I ever needed more AR-15s Unknown on Sep 13th 2016
We finally made our first pour and it came out reasonably well. There were three pinhead size air bubbles in the rear of the buffer tube housing, but otherwise perfect. I do note that the buffer tube housing is too thick to accommodate the buffer tube for either the standard A-1 or A-2 military stock (we used an A-2 to replicate an early Vietnam era military rifle) without modification. We had to do some inletting to accommodate the stock. I agree with unknown below that the reinforcing brace would be better pre-bent. All-in-all this appears to be a very good product and resulted in an easy build-out. The finished rifle functioned first time on the work bench test. Smoke test soon. Ken Willis on Sep 11th 2016
Finally had a chance to use the kit. The first pour I messed up on the timing and wasn't able to get a complete pour before the resin hardened. The second time was perfect. I had no air bubbles in either molding. If you follow the instructional videos you will have success. It was easier than I though it would be. Can't wait to get a chance for a third pour.

Says here on the webpage above me....."everything you need to pour," except Silicone. Something so important they mention it several times! I am unhappy, that I get started on a project after finally having some free time and cannot go any further then a few minutes in. False advertising! It may seem petty, but I am writing this at 9:34 at night. My kids are asleep and I cannot go buy silicone! Christopher Robert Thompson on Jul 27th 2016
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
