Hi Mark,
Got the pics, thanks!
Yes, I can see the crack.
I am going to guess, even if left as is - that gas block is going to be very
solid. When you remove it, it won't be easy.
I would recommend replacing with a low profile gas block and retaining
screws. If installed correctly, and a extended rail covering it from
impact, they are not coming out. When we remove front sights, it takes
about 2 minutes. When we remove our low profile gas blocks it takes about
20 min with MAP gas to get it free. The set screw is set into the dimple
and secured with loc-tite. It's a pain to remove.
Otherwise look at the DD clamp on low pro gas block. Those work as well.
