RMC "V" peep I put one of these on my muzzle loader and wanted to give my opinion of this hybrid. Its not a buckhorn & its not a peep. I couldn`t find a tang sight so I went this route for Ol smokey and am very pleased. My shootin eye centers instantly as a peep should, the open top allows for good view of target but the eye stays centered and good sight picture is retained..I give it a thumbs up. This sight is currently only made for muzzleloaders however I wanted to share my opinion of the product.. It does come complete with mounting base. I also put a hi-viz fiber optic up front, its very good in the dark woods and lo light.. P.S. WA State does not permit scopes on muzzle loaders.
