Nice work!

Thank you kindly.
Hoping to get the barrel assembled and pressed in/ headspaced very soon. The next challenge will be the bolt face modification

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.

Donor barrel
Attachment 532799

The donor rifle is taken apart. The T97 Barrel is stripped of the devices and has the bushing pressed on.
Attachment 532803

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
Attachment 532804

Some unused notches for the pins will be filled using welder and then machined flush, just for the aesthetics
Attachment 532810

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.
Attachment 532812

The 223 muzzle. Planning to put back the "bird cage" T97 flash hider on it when finished
Attachment 532813

To be continued

So when can you ramp up production on these for everyone else,, AND KEEP THE PRICE BELOW 1K. might even have to jump into a failed pre order pyramid scheme

nice work btw look forward to seeing the finished piece

Guys,

As recommended by Curtton, I have started a new thread, relocating my build report over there. Also added a new post - just my thoughts on the gas system length. Thank you All!
