Hi Everyone: I'm new to Nitro Express and the forums. I'm changing out the front blade sight on my Merkle 140-2, 450-400 & would like to know if anyone can tell me how to safely remove the factory sight. Is it pinned or under pressure from a small spring in the sight base or is it just tapped into a dovetail? Any help will be appreciated before I take on the task. Also, has anyone seen an aftermarket rear express sight for the Merkel's? In looking into dark shadows it is very difficult to make out the top of the express sight and I'm thinking that a white outline or ? will help me see the top of the sight and more quickly line it up with the top of the front blade sight.

Thanks,

TDBIII
