For conversation purposes (I agree), I also like customization, as long as it is NOT part of the critical path, part or system.
If the magazine is designed to feed and manage the “presentation” of the round and does it consistently and without fail, I will buy that magazine, regardless of how many others I have, as I am sick of having a magazine that “almost works for some chassis” with all these “adjustable” features that just adds to points of failure (basic reliability concepts).
For trigger, that is in a critical path that affects sear engagement, pin fall and timing in concert with the bolt and firing system. BnA triggers at least offer low, medium, high top sears and some adjustability and allow user servicing, but it still has to be compatible and functional with the firing system.
Chassis LOP is in the “user’s” critical path and can be altered without affecting the action’s critical system.
I have several different precision 22LRs and they all differ because each fixes one flaw or another in the other rifle system and yet introduce a new one of their own.
I’d really love to see one rifle system that is completely and reliably functional for its stated use case (that is not so narrowly specified to exclude conditions to cover for inherent flaws and compromises).
I am not a mechanical engineer, so I use this passion to learn from and enjoy the experience.
