As a gunsmith I have learned a LOT about the 788.
Strong points were:

Super Accurate.
Super fast lock time.
Inexpensive.

The bad point is:

The bolt face is recessed for the typical Remington extractor, but the front of the bolt nose is very thin, so I have seen a few dozens of them break no the extractor, but the bolt face itself that is holding the extractor.
To get a new bolt is impossible. I have 3 customers that own them in 222 and 223 calibers and all have been trying to find bolts for about 5 years.

Of course you also get broken extractors now and then, which are also quite hard to find, but so far I have been able to replace every broken extractor on a 788 that has come through my shop.
As long as they are available they are not hard to replace, but those supplies are running low these days too. Someday I expect to not be able to get them either.

All these customers have replaced the rifles so they can have one to use and are just hoping to get parts sometime off the "used market" when they become available from some scrapped out gun.

Funny thing is that 2 of those customers replaced the 788s with CZ 427s. Did I read correctly that you went the other way?
If so, why would you do that?
Just curious.
