Will they fit? If not what peep options are available for the older models (1973)?
My used 1977 444S came with one mounted and ready to go, so I say yes. Midway has some info in their ad about fitment. Peeps sure are a good way to help sight a lever gun without the bulk of a scope.
Is that thing fairly stable, I mean if you bang it around in the truck does it lose its position?
I've had one on my '79 M444 for years & have found it to be Totally Reliable & Very Rugged.
It has Always Held it's Zero & now rides under a Weaver K3 steel Scope as a Backup Sight.
It Seems to Me that A Lever Gun in a Large Caliber Will Be Very Handy when the Fecal Matter Hits the Rotary Air Moving Device.

With my 1970s 444 I mounted a Williams Fool Proof which is the screw adjustable version of the 5D. It has been on the rifle since and has given outstanding service. I'm not abusive to my guns but they are not babied either. It was a hard working rifle for decades in heavy forest mainly and the Williams Sight was trusted, it never moved and was easy to re-zero. If you re-zero a lot I recommend the adjustable Fool Proof. The 5D I used on another rifle was sturdy but adjusting the sights was a bit clumsy, loosen a lock screw and the sight shifts a bit.
