Thanks for all of the support.

Yeah, I am the one who posted, but it may not always be me, I guess I will start signing my posts.

Thanks again for trying our mags, and thanks for the nice write up and pictures.

About 7.5 inches. Same as most other poly mags.

While the hybrid mags with steel feed lips are very robust, they are not without their drawbacks. The steel is not stainless, thus is very prone to rusting. The steel is also far less chemical resistant that our plastic.

When we started our design we thought if we could make an all plastic mag with feed lips that are tough enough to hang with the steel, that would be a victory because our plastic is more chemical resistant, and won't rust. Also, it's important to know that cyclical stress is an important factor for these feed lips. Each time a round is stripped off and the next round pops up, the feed lip see a good amount of cyclical stress. Over time and many cycles most materials will weaken and eventually fail. Now please understand we are talking about many thousands of cycles, but with that said, our material was testes at 1000 psi and it took 100,000,000 cycles before the plastic failed.

I can confidently say that our feed lips are are in fact tougher than the steel hybrid mags feed lips. We had to drop these mags on their lips from a lot higher than 6 feet, but the steel bent before ours (in fact, we haven't been able to get ours to break yet...). Now please understand one more thing, we are not at all saying that the hybrid mag is not tough enough, because it certainly is very impressive. We are just saying that our is as tough, and it won't rust.

The reason I'm getting into such detail is to make sure everyone understands that we have put a lot of thought and testing into these mags and we think our solution to the unique challenges presented for the AR mag is the best combination of toughness, chemical resistance, and thermal stability on the market today.(plus it's transparent)

And as far as the Lancer mag specifically is concerned, our mag without the coupler is several dollars cheaper than a lancer, so that's an advantage...

We are working on a video that shows our mag being dropped from about 20 feet into concrete fully loaded without breaking, that will be coming shortly. I can assure you that our polymer is not at all like the typical glass nylon used in most poly mags. I also want to clarify the statement that our plastic is not "stronger" than steel. And while I know this will come across as semantics, I think it's important to clarify. Our feed lips are more than twice as thick as the steel hybrid mags feed lips. This along with our special plastic allows our feed lips to endure more impact (energy) without permanently deforming than the much thinner steel feed lips.

The term strong usually refers to ultimate tensile strength (the amount of strain a materiel can handle without permanently deforming) and in that regard, there are not many materials that are better than steel. However, as said before, we went a different direction when we decided to use a material that can bend MUCH farther than most steels without permanently deforming. This is what gives us such incredible impact resistance.

As far as chemicals, there are many that will react with steel but not our plastic. The easy answer is hydrochloric acid. It would dissolve the steel in short order, but you could leave our plastic in it for a week (we did) and it would not be changed in any measurable way.

Also, I have read the unscientific plastic magazine comparison thread, actually several times. I find it extremely interesting and to be honest, it inspired many of our outstanding properties. Before we started this project, I had many mags fail on me from accidentally dropping them ( I guess I am a little more clumsy than some people)  and once I saw that thread I knew it was a problem that pretty much all poly mags suffered from. I hope the next time that guy does a mag test he will include ours, I'm actually counting on it.

Ultimately, I have heard many times, as I'm sure most people on this forum have, that mags are disposable items because they fail fairly regularly. One of our hopes is to somewhat change peoples mind about what a mag CAN be. Meaning that if we make them well enough and tough enough people won't have to treat them like disposable items. Unless you lose our mag, you shouldn't have to replace it. Since this platform came out over 50 years ago, there have been remarkable advances in processes and materials. In my opinion it's crazy to think we couldn't make a better mag in today's age than 50 years ago. I think the weakest link now is the spring, which should be good for over 20k rounds.

That was one of our goals. I'm hoping that when you guys get a chance to use them, and test them a bit, you will agree.

(ps...sorry for the long winded responses. I'm just wanting to give you all some background as to our thought process, goals, and ultimately what we have achieved with these new mags. We think in the end they will be a game changer.)
