257Robt,
I had a Model 742 with a Redfield side mounted aperture sight. The rifle did require a rather high front sight. The aperture rear sight was mounted rather high and this arrangement did suit me, allowing rapid and easy target acquisition.
I presently have a NECG peep that attaches to the Weaver scope mount base on my 7400 Carbine. This arrangement works, but I would not use it as my primary sight system, as the sights are not positioned so that I can acquire a sight picture quickly. I could not use the factory sights at all, having to creep and crawl around the buttstock just to get a sight picture. As the NECG peeps are back-up sights for the scope I use (with which the rifle/sight set-up acquires targets very well), I can accept the arrangement.
BTW, when I had the peep sights installed on the 742, the gunsmith used a temporary peep sight apparatus to determine the proper installation height for my handling of the firearm. He than drilled and tapped and installed the Redfield sight at a height that best suited my physical requirements.
