tru-glo sights are available from Cabela's website. i put a set on mine and i loved the sights, BUT they do not fit the Ranger model. they only fit the Traditional model. i think they were about $30. i was bummed that they didn't work with the Ranger. it will shoot, but my groups were about 8 inches high at 50 yards with the adjustment bottomed out. they don't appear to be all that resistant to rough treatment though. care must be taken not to whack the sights on anything. still they're probably the best available option for the '94 in low light.
