Really don’t have any experience with them. I looked at them a couple times, but the extractors turned me off. Bought one of the 14” O/u’s when Martin brought them in. (No light rail). Didn’t use it much so I sold it. Then wound up with a “Tombstone”. SXS with 12” barrels. Really like it, but again it’s not getting used so may be on the EE soon
The other thing to consider is that if you found any SXS 12 gauge you liked, including the Condor, or one of the 12” or 14” ones out there, it wouldn’t take anything to drill and tap a couple holes in the rib, and mount a piece of Magpul pic rail on it.
