I am not sure if the lightweight one would still stop the AP rounds or not, I just know they rate it for m193 @ 3100 fps. AR500 Armor® level III+ lightweight body armor is capable of defeating 5.56x45 M193, 5.56x45 M855/SS109, 7.62x39 (AK), and 7.62x51 M80 Ball (.308 Winchester) rounds.

Coated with industry leading PAXCON (a division of Line-X) spall and fragmentation protective coating. It's level III+, but it goes on to say it won't stop AP. |

Yes, but are you saying the plus factor is due to the coating? because in the OP it says the steel is made to a harder spec. which is what gives it the plus spec. The steel can be harder all it wants, but the layer of 'not steel' will allow deformation of the projectile, energy spread, energy redirection, and accentuated yaw, among other things. It may not be much, but it's still significant. Imagine, if you will, the projectile and plate immediately after contact. The projectile/shockwave is crushing the material in front, but that is slowing down the projo like a two wheel drive pickup in slushy snow. That material that is being crushed out of the way has to go somewhere, so the pressure spike is distributed on a broader area and starts pushing the surrounding material, which naturally separates from the plate at the border of the dissimilar materials. |

I'm not saying the difference between the 3 and 3+ is the coating, but it helps.

Yeah, I'm not saying the difference is the liner, but it does have a significant effect. Imagine the above description relative to a motorcycle hitting slush on the road (5.56mm) vs. a straight truck (7.62 whatever). The motorcycle is gonna flip end over end a few times before the straight truck starts slowing down. That's why 5.56 is an amazing up close and personal round and a 5.56 SBR is the 'best' HD weapon. Because instead of a vehicle driving though slush, its actually a bullet in an elastic solid. PS. Don't let the 300MEH fanbois know I dissed their round for HD. |

Something I learned a while back is that if my (internal, external, and terminal) ballistics predictions don't match test data, it isn't because its a fluke, its because I didn't correctly account for all factors. There are no misses, either. Every single round went exactly where physics determined it would. View Quote View All Quotes View All Quotes Quoted:

Cmon, dude. That stuff is essentially bedliner (some companies actually use bedliner). It doesn't do dick for stopping the round. There are no misses, either. Every single round went exactly where physics determined it would. I understand all too well. And I am also certain that even a .22 CB cap could make it through that bedliner. You have seized on the bedliner as being "the" factor that is causing the discrepancy, but there are many possibilities.

I've said like 3 times that the 'not steel' in the front isn't all of it, but has a significant effect. I'll concede that you don't think it's the only factor. But your assertion that it has a significant effect is guesswork, at best. Even the Old Painless BoT tests demonstrated that thin, relatively soft materials immediately in front of the target (like frozen clothes, thick jeans, etc) made essentially no difference in rifle penetration or performance. Different scenario, sure, but at least an analogous physical setup. That bedliner is thin (<1/2 bullet length), very soft (relatively, usually a urethane blend), and isn't spaced out from the plate. All of these factors reduce its effects on bullet yaw and deformation before it reaches the plate. |

The steel can be harder all it wants, but the layer of 'not steel' will allow deformation of the projectile, energy spread, energy redirection, and accentuated yaw, among other things. It may not be much, but it's still significant. Imagine, if you will, the projectile and plate immediately after contact. The projectile/shockwave is crushing the material in front, but that is slowing down the projo like a two wheel drive pickup in slushy snow. That material that is being crushed out of the way has to go somewhere, so the pressure spike is distributed on a broader area and starts pushing the surrounding material, which naturally separates from the plate at the border of the dissimilar materials.

I can't tell if it's ceramic ablation or something else coming off the plate and landing on the ground.
However, something is terribly fucky with this and I smell some serious bullshit. If that's AR500 steel, polyurea liner, and nothing else then there is no way in hell it will stop real black tips travelling at full speed. No. Way. Here's my revised breakdown of what I believe is going on in that video. To my knowledge, there has never been a .308 "Black Tip"... only M2AP. (I welcome any correction to this information.) That suggests to me that someone reloaded .308 rounds with black tip bullets. If that's true, then it raises many questions, not the least of which are: What velocity are those bullets actually travelling? In the video, the statement is made that the plates will stop black tip at 3100fps. If that's true, that's faster than M2AP so why not just call it a level IV? After all, they would be the first company in the world to essentially defy physics and create a level IV plate out of 1/4" AR500... so what gives? In other words, I don't believe it. I would like to hear from someone at the company that can defend this. If they want to claim that this plate is AR500 steel only and will stop Black Tips travelling at 3100 fps... or even 2550 fps... then I'm going to buy some and send them to Chesapeake. I believe there is some serious deception going on and I do not say that casually. |

Ok, I finally found some info. M61 was a NATO black tip in 7.62x51.
It was so devastating that it had less penetration that a solid bronze or brass round. No wonder it never came up for testing while I was in the industry. I now have zero doubt that AR500 stops that round. I only wonder why it's worth bragging about. |

AR500 lvl 3+ armor stopped 4 7.62 NATO AP rounds at 5 yards. I would have expected the AP round to penetrate lvl 3+ armor but that was not the case. 10mm and AR500 videos said a lot about speed vs bullet material/design. I saved the video link for future debate on the subject. |

It could be chemically "AR500" and just ordered from the mill at a different heat spec. Like 10mm says "velocity matters" relative to piercing steel, the inverse is "hardness matters" in preventing that penetration. |
