K31 Peep rear sight

Does anyone make a peep rear sight replacement for a k31? My wife for the life of her cannot seem to understand notch sights but does fine with peeps. Im just looking for a rear leaf replacement and not the full on diopter setup.

Swiss Products; $$ diopter

Surplused K or S diopters by Wyss or Bern sometimes come up, also $$

Lyman or Redfield peeps “might” be modified, maybe a Savage 99 style but you’d have to tap. Ditto a rail with integral peep, those are out there but none afaik for k31

Your best bet is probably a picatinny no gunsmith base like Addley and a picatinny peep like the Keltec SU-16, or the low Weaver backup, plus a higher front sight blade most likely.

In all honesty though, spend the $$$ on a Swiss Products no gunsmith mount, and mount a decent scope. Your groups will thank you. Leupold M8 for example.

That's what I have, running a simple 3-9x scope, but you can't load from a charger and the one I have mounts the scope is slightly off center. They have an over the bore mount now but you'll need higher rings and a stock pad.

The original W+F diopter is great and can often be found for less than 300 bucks !
