I believe that Zheng was/is a member here. There were videos of many of his development steps here at one time. He would put 5 round of 5 different cartridges in the mag, then go from rifle to rifle switching that single mag. It was impressive.

Well it has my attention. I shoot .223, 300 BLK, 6.8 SPC, 6.5 Grendel

I am scheduled to receive one for evaluation in the very near future.

Any updates on this mag?

I have 2 of the Unimags and they work great in my Grendel.

They fit very snug in the 4 lowers I have tried them in, will not drop free or even come close to it.

Feeding and bolt hold open has been 100% with mine thus far. High quality mags and the lack of dropping free does not bother me for my usage.
