I was thinking of the MP5 some swat-ies use and other 9mm rifles. Well I was thinking that the 223 frags on impact as it travels through the thinner armor so if you had helmets and flack jackets you might? might? be OK . The van is going to have 2 seats in the front and 4 seats in the rear in a row along the drivers side of the van and 2 more seats that are back to back on the others side in the rear . well the point is I'm not making an armored car just something with a little more protection . Rifle protection would be great if I could find steal thick enough that's almost free $ I'm trying to do this without spending a lot of $$$ . and by using stuff I already have .

The biggest cost would be the NEW tires what type of tires would be best against bullets I was thinking of getting tires with a high load range so it has thicker sidewalls so I could run on flat tires with a hole in the side wall .
