JJ,
On another .375 of mine, I have the same Warne QD rings and have the same Ashley peep sight for it as you have. It is a cool setup. I always wanted to install a grip cap with a hidden compartment that I could store the sight in , but I never did.

Brockman's used to make a really cool base for Talley rings with a pop up peep sight shown here.

Not sure if they still make it or not, but I always thought it would be cool, although it looks somewhat fragile. I've never used one but did correspond with a guy who did and he loved it.
