I suggest you take a look here
and consider the following
60 round and 100 round
compatible with M4/M16/AR15 type weapons
they promote by showing someone in military garb
but as far as I know such large capacity magazines are neither standard issue military equipment nor in fact encouraged in the armed forces, although perhaps someone with military experience than mine in the mid 60's might care to comment.
Please tell what legitimate purpose such a large capacity magazine has in civilian hands?
For weapons with a muzzle velocity of 3000 feet per second
whose bullets are designed to smash and maim human beings
Just so you know what we are up against

You too can legally be prepared to take out a police force for less than $5,300

Just did a little googling to find out costs
brand new AR-15 Bushmaster    $1,700
10 100-round magazines             1,790
1000 rounds of ammunition        1,750  (on sale)
total cost                                   $5,240
Oh, and I should mention about that ammunition
it is SS-109 armor piercing rounds
so you can shoot right through the police car
and right through the policemen's vests
and this is all legal


Consider some comparative costs

in my last post I noted the cost of a Bushmaster AR-15, without rounds or magazines, was around $1700.
I have also just checked prices on various models of Glock handguns, and found they range from $219 up, although in general they cost in excess of $300.
Since someone had suggested I include in the cost of outfittin someone to take on a police department the cost of body armor, I ust explored that

First read this
How does a person convicted of manslaughter obtain 18 assault weapons and other firearms, along with 40,000 rounds of ammunition? Well, according to NBC News, a White Supremacist from Ohio who also happens to be a convicted felon did just that.
Got your attention?   Well, there's a lot more . .
