Another one got derailed
244 pages in is not a bad record. Show me any other gun forum with even one thread having this many pages of posts.

Edit:
Plus, this is just some banter while MB is very busy getting all his new shiny stuff ready to ship. It’ll get back on track, worry you not.

thermal fit upper assembly question.

Aeroshell 64 on the barrel extension and threads. Heat with a torch or heat gun. I use a torch and typically only need to hit the upper with it for a few seconds.

If you want to mate the extension to the upper as closely as possible, while still being able to disassemble it in the future, use loctite 620 on the extension and aeroshell on the threads.

Number of shots to establish zero

3-5 to get initial zero after a big change (new barrel, optic was removed, etc...). 1-2 to get on the dot, 2 more to verify. Somedays are rough and it takes me an extra 2 or 3. Any more is almost always an issue with my form or how the rifle is setup.

1-2 to verify zero prior to performing.

Keep a practical performance expectation or you will be chasing your tail. I don't care if my AI can typically shoot <0.6moa. If the groups are centered around the dot within 0.8moa, I am satisfied and move on.
