Ever wonder if an IBA without SAPI plates will stop a 7.62x39mm bullet at long range?
Well, the guys at Demolition Ranch just did their own little experiment with a couple of sets of body armor generously donated by a curious viewer. Though he refers to each vest as a flack vest, it appears as though the first one is a Personnel Armor System for Ground Troops (PASGT) vest, which was in common use by the US Military from the 1980s until the mid-2000s. The second vest appears to be a complete set of Interceptor Body Armor (IBA), which started replacing PASGT in the early 2000s. The PASGT was designed primarily to stop shell fragments. Though there weren’t any plates in the IBA during the test, as you can see in the video, the IBA has pockets that can hold ceramic SAPI (Small Arms Protective Insert) plates that are rated to stop rifle rounds. Even without the plates, the IBA is still rated to stop 9mm pistol bullets.
First, they tested these vests at short range against a 9mm pistol, a shotgun firing birdshot and slugs, and a rifle chambered in 7.62x39mm. Not surprisingly, the rifle bullets and the slug easily penetrated the vests while the 9mm pistol bullets and the birdshot were stopped by the vests.
The results of the (admittedly unscientific) test got a little more interesting when he decided to see if the IBA would stop a 7.62x39mm bullet at 375 yards. Watch the video to see what happened.
Though it was not really surprising when you consider how much slower even a rifle bullet is traveling all the way out at 400 yards, it was interesting to see that even an old IBA without SAPI plates might stop a rifle bullet at long range (though I wouldn’t want to test out that theory in real life).
On another note, it was also nice to confirm that the kevlar groin protector on an IBA will stop a 9mm pistol bullet. Man, that looks like it would really hurt though…
