...I recently bought a Colt Match Target MT6601(20" bbl, 1/7 twist, no flash hider). I decided that I wanted to shoot an "as issued" rifle instead, so I bought a govt profile 20" 1/7 twist crome linded barrel and installed it today. Is this as close to an "as issued" A2 rifle as I can get?

How close you are will also depend on the trigger and hammer pin sizes and whether or not your receiver has a sear block.

Hammer and trigger pins appear to be 1/8" and I have no idea what a sear block is. The rifle is a 2008 MT6601. Has 1/4" receiver pins. Can't do anything about the "Match Target" roll mark, just trying to get as close as possible.

Your pins are normal, and I believe that by the time yours was made, Colt no longer installed sear blocks (someone correct me if I'm wrong). BTW, a sear block is a machined piece of metal that sits just aft of the FCG in the lower receiver (picture below). Looks like you're good to go!

Outstanding!

I am just going to leave it "as issued"

I like the simplicity

I am going to build another upper for the HBAR that I took off the rifle so I can have a spare...
