Longziz #2, the universal AR 15 Magazine

[Hobster]

Impressive! I am very curious as to how these hold up over time. One magazine that feeds all of those calibers reliably? I would have never believed it without seeing it. I'm curious to see how they hold up in full-auto and bump-fire situations as well...

Hi Longziz! Glad to see you back.

Keep going on the magazine, and I hope you do very well with it.

I can do full auto 5.56 and 6.5 Grendel if it helps, but I don't have the other calibers.

Good luck!!!

When the pre-production prototype is ready, i will post here. However, it maybe months later. Anyway, I will keep you posted.

I've been doing long-term, end-user field and range testing on a number of products for years. My end-user conditions of use profile covers multiple shooters, mostly military, and different climates and regions, to include high desert with 40 degrees + Celsius, to arctic wet conditions in -30 Celsius.

For example, I have been running long-term endurance by end-user testing on Vortex Optics, Nickel Boron BCG's, and some other products since 2009 in the above conditions. What I've learned is that there is a place for common industry testing with compressed-time reliability testing, as well as long-term end-user testing in varying conditions, where you really get to see how a product performs.

I have conducted formal testing for manufacturers before, and am familiar with Total Quality Management approaches, ISO standards, but most importantly: Joe testing, where soldiers use and abuse products under adverse conditions that defy the imagination of lab technicians.
