I have a model 14 in 30 rem that I was lucky enough to get a reddington peep that mounted to the 2 drilled and tapped holes put there for just such a sight. It makes meat just fine. They carry and balance like a fine shotgun.
What is a "reddington peep"?
The only peep sights that I recall seeing for the Remington 14/141 series rifles were made by Lyman and Marble's.
Can you post a picture of it?
EDIT: Do you mean a Redding Model P shotgun peep sight?
