yeah, I don’t have much rail space. She’s a tiny little thing. I just might have to make a few adjustments to get the spacing right. It shouldn’t be a problem.^ With your setup as it is above, I think you'll like the OWL.
The people I've met are all love/hate about the OWL. Chiefly, their attitudes revolve around the mounting of the OWL and how it interfaces with their shooting ergonomics and/or other cool-guy equipment setup.
