What is the best all steel peep sight for a Marlin 336?

Lyman is a reciever mount. All steel. I am not sure who else makes them for the 336.

The Lyman sights of today are aluminum, but the older ones were all-steel. I keep an eye out on Ebay for all-steel Lymans as well as the Redfield 102, and have found some pretty good deals in the past couple of years. Both are excellent sights. The Lyman has click-adjustable windage/elevation, while the Redfield must be zeroed and locked down with screws -- no big deal with a hunting rifle.
