Here is the peep that I use on my Encore:
I tried the Williams peep sight but it did not give me enough elevation adjustment. Also, this one mounts on top of a Weaver base. The Williams peep fits into the scope mount holes. Using this setup enables me to use a scope with quick release rings and go from a scoped setup to the peep sight without having to use a wrench to remove any sights, bases, etc.
This sight is available at Cabelas for $79.95 and is a much higher quality sight than the Williams IMHO.
HTH,
