I think I would go straight to the source, at least 1) see if they even make one, 2) get a model number and then Goggle it and see what kind of deal you can find on them.
Late getting back to this . . .
Yes, I called TruGlo and inquired about the peep/picatinny combo. Turns our it was an OEM request from Remington. They, TruGlo, made the request number of product and sent them off to Remington. Unfortunately, there were no 'left-overs'. With Remington's questionable future - for Remington branded firearms - I'm not holding my breathe waiting to see if one of the peep/picantinny rails can be had as a 'parts'.
