do they work with the original front sight? ive read alot of reviews that say they dont and im not a fan of fiber optic sight posts. reviews ive read say they are prone to breakage."Best" is difficult. Some shooters might prefer one, others another.
Recently I put a Skinner peep on my Marlin 39A, and it's working out just perfectly. It's very light and compact and I think it compliments the rifle nicely:
I've also happily used Williams and Lyman peep/receiver sights on several of my lever action rifles over the years. They're excellent too. A bit bulkier, but easy to adjust and time proven:
I think that the Skinners have a nicer appearance, but the Lyman and Williams sights are time-tested and work great. Pretty much up to you as to which you prefer.
