There's something about this post that I just... like.

Interesting- I haven't seen that yet, especially in the newer "Colt Defense" marked weapons. I also do not see any proof stamps near the dust cover. I am familiar with their occasional M4 ramps that are cut post-anodization, but again not since the change to Colt Defense.

The "C" marked bolt is another Colt item that I have only seen on the civilian market models (i.e. MT6400C with Colt's MFG rollmark). All of the CD marked ones I've worked with had the MPC designation.

Thanks for the post; I enjoyed it too! I do not know if Ekie is a member here, but he would probably find your info interesting as well for his Colt database purposes.

I was under the impression that A2 uppers had the ramps cut post to match the extension and A4 flat tops came with the pre cut ramps.

So every carbine arriving at your agency receives this pre-acceptance inspection?

Excellent post! I wish I was there to help you do the acceptance inspections and live-fire

Looks just like the two of them I bought last year.

Not sure what the standard is, if there is one. I suspect it changes with available components. My own 6520s, and 6520s from the 2005 buy, were cut pre-anodizing.

Any firearm (handgun or long gun) used on duty, whether personally or agency owned. Eliminates a lot of problems down the line.

Most neighboring agencies do it to, to one extent or another. Very useful in purchasing and deployment decisions.
