The only way to combat that is to have it milled off. But that's only nessisary if you have or can afford one.

Nope...not even one of those. It's got to be a bolt action trigger

I'm not sure if this was an " overreaction " or merely a company's way of insuring that the sale of their products would not be a problem for the end user of their products (civilian market)
You have to take into consideration the political bias at the time, quite frankly, I can't see the expense of "converting" such a lower vs. purchasing any number of "post- ban" lowers available at a lower cost. I'm not a Colt devote' and don't own any Colt AR's but would consider a Colt lower w/ a sear block a collectors item, a testament to an American company's efforts to insure the 2nd amendment rights of citizens of this country.

You realize they are pre ban ( Clinton Era Ban)?

Don't the new M4 marked 6920s have an un-milled portion in the fire control group area where an auto sear would go?
I thought I saw one like that recently.

to block use of sear, duh.

The sear block was installed by Colt during the pre-ban era so that either a drop-in auto sear, or, a standard auto sear/sear pin could not be installed. All AR-15 lowers now (and have been for a long time) are designed with thicker walls in the area where the auto sear/sear block would go. So, if you see a lower with no sear block doesn't necessarily mean that it's a pre-ban lower. To get any type of auto sear to fit would mean that you would have to machine away the extra material on the inside of the lower.
