Yes, very nice. Looks like they did a good job with the sear block holes

I’ll add a little more for those of you who are contemplating having the sear block removed from your Colt lower receiver. I am aware of two companies who can remove the sear block: ADCO and Compass Lake Engineering. (If you know of another company, feel free to post and let others know.) My first thought was to send the lower to ADCO, but their gunsmiths were on vacation. I wanted to get the lower to U.S. Anodizing while they were accepting small orders, so I explored other options. I found that Compass Lake could remove the sear block, was cheaper, and would have it back to me relatively quickly.
When Colt installed the sear block, they used a large pin that protruded through the right side of the lower and a second pin that extended into the bottom of the lower. (Some sear blocks also protrude through the left side of the lower.). When Compass Lake mills out the sear block, they also remove the part that protrudes through the side(s). As part of their service, they will install a steel plug where the sear block protruded through the side (just above the selector). If you are going to have the lower re-anodized, you will want to install that new steel plug after it has been re-anodized.
If you don’t want to install the steel plug provided by Compass Lake, U.S. Anodizing can install an aluminum plug into the offending sear block hole. U.S. Anodizing will do this before they re-anodize the lower so as to make the hole/plug less noticeable.
One last thing to consider, if you are going to have your lower receiver re-anodized after the sear block has been removed, all remnants of the bottom pin need to be removed from the lower receiver. That pin is also made of steel and cannot remain in the lower receiver.
