The makers of the well-known and excellent Patriot III steel rifle plates have been busy, and I have just gotten wind of a project that has been in the works for over a year, and is nearing completion.
Just a few details are known at this time:
Most advanced Ultra-Hard steel in the world
4.5mm/.178″ Thick (Uncoated)!
Stops M193 @ 3300 FPS as well as M80 ball and M855, all lesser threats
Weighs ~3.4 Lb.!
This is only .3 lb. heavier than the Midwest Venture STX plate of the same size, is .37″ thinner, and will stop M80 ball (true level III+)!
No word yet on release date or pricing, but even so, it sounds like they have themselves a winner. Keep your eyes on Maingun’s site and this blog for more information!
d-rmor gear 
Probably goes without saying… but I assume we can get some spall guards to fit these? I sure hope so.
Yes indeed. Will be making both custom Splash/Spall guards to fit, as well as Extreme Duty Plate Backers in the same profile.
Are these what are now being sold as the Patriot Plate II?
