For the past three years, I was trying my best to bring it from a prototype into a product. Three years seems too long for a project like this, but for my case, it seems it is the way it is. Since ARFCOM strickly prohibit advertising, and I am on the waiting list to be their industrial partner, I can't start promote it there, so I am really elated that I can do it here.
Long story short, I am going to offer an AR15 magazine that capable of feeding ANY caliber Center firing RIFLE cartridge to AR15 rifle, or any other rifle that accept STANNAG 4179 GI magazine. Currently, the tested caliber and capacity are as follow:
223/556/300BLK: 30
5.45X39: 29
6.8SPC: 26
7.62X39: 25
6.5 Grendel: 24
458 SOCOM: 12
For my own test results, please go to my youtube channel here:

My friend Oleg Volk have some preliminary review and exposure here:

Due to resource limit, other odd ball caliber are not tested, but I am asking whoever has those to pitch in to help.
To expend the test both for my potential customer and general shooting enthusiasts, I am giving away 10 collectible Unimag for the THR member here to test and keep. This is offering to general shooting sport enthusiasts, so if you are an professional firearm reviewer, please contact me directly so you can by pass this selection. However, please do provide your past work so I can recognize you.
Here is my selection standard and request, plus some info of what you are going to get:
1. The magazine will come with Cerakote coated Stainless Steel in black, with black follower. The production follower color will be different. It has the same exterior dimension and look as a regular STANNAG 4179 magazine, with some distinguishable features. The magazine shell will be serial numbered, and the number will be between 001 ~ 200. That means, only 200 of them will ever be produced. The availability of the magazine will be either by the end of this year or the beginning of next year, depending on how soon my supplier can provide the sample.
2. The selection standard is that you need to have at least two AR caliber upper to participate, the more different calibers, the better chance being selected.
3. Only center firing refile caliber is considered eligible, pistol caliber and 22LR are not considered as eligible.
4. For participants who claim he has the so called caliber, I need you to link your previous post on this forum to show you actually have it. Borrowing from a friend do not count.
5. You are welcomed to do any test with the magazine. However, I am NOT looking for any destruction / torture test. It is a metal mag, it will be very similar to other metal mag strength wise. If you choose to do it anywhere, by all means, but there is no replacement.
6. I am asking whoever received the magazine post his/her results here. Picture will be appreciated, video will be more suitable. Please specify what caliber was shoot for how many rounds, with how many times of jam (or lack of), plus possible cause, if identifiable.
7. I will choose some best representative feedback from you and offer further free stuff.
8. For member that living in a not-so-gun-friendly states, please check your local law to make sure your state allow "large" capacity magazines. I will reserve the right not shipping my magazine to states like CA, NJ, NY, CO, DC, MD, etc.
I will reserve the right of selection, however, you are all welcome to point out any inconsistencies and holes of my rules and requirement. I will answer any question you may have, but please be patient if it is not responded promptly. I am still busy tweaking the last leg of the manufacturing.
Thank everybody who would participate, and thanks THR for providing such opportunity.
Best,
