Switched my rear sights to Peeps. Everything I have either has scopes, light sights, or peeps, since I can't see the sights and the target at the same time. Got a new NEF .17HMRF for Christmas put a light sight on it. My huntsman has a peep, as does my .50 cal Encore. Scopes are a no no here for muzzleloaders. Would like to see that changed.
You know though, what really burns me up is that the eye doctors keep telling me it is an age thing. Yet my 78 year old Dad can use open sights just fine.
