As I promised to a couple of members, going to post the progress pics of the 223 conversion work.
With the prayer, work has started.
From one of my previous projects I had a take-off T97 barrel which proved to be a good base for this conversion so far. The shank was smaller than the T81 trunnion opening, so it required a press-on bushing. Other than that, barrel diameters where devices were installed are very close, within the +/- 0.001" which was a good surprise for me. If the T97 barrel was not available, an AR15 barrel would be a good candidate.

The donor rifle is taken apart. The T97 Barrel is stripped of the devices and has the bushing pressed on.

The T97 barrel is at the bottom - barrel shank is machined to size, barrel devices are migrated onto it just for the fitment check. On top is the stripped T81 barrel

Some unused notches for the pins will be filled using welder and then machined flush, just for the aesthetics

Existing gas port will be plugged with the threaded plug. It will be right under the front sight base so it going to be completely hidden. New port will need to be drilled.
