    I kinda like the idea. The keeper would have to be pretty damn well engineered. Not sure if something like the internal spring clips geiselle uses on their trigger pins would hold up but that seems like a reasonable place to start.

    A single split pin is adequate for low-pro gas blocks-- 3/16 or even 1/8. Since they don't have the height, a bonk on one imparts much less stress on the pin-- and of course they are often protected anyway by the fore end.

    For original-design FSB, taper pins only as far as I'm concerned. Several outfits are using straight pins but they are too dependent upon a perfectly-sized, reamed hole. I've seen a good many of them missing or hanging out 1/2" getting ready to take a trip. I LocTite them. tap them back in, and stake them. Might create a hassle for whoever tries to take it off some day but.... I only care about keeping the gun running now.
