I know, yet another red dot smith 41 optics question! I searched but could not find a specific answer to this.
Does anyone know specifically which red dot optic will cowitness with the Model 41 PC.
BTW, I checked with Smith and they said they don't know. Apparently the developed this gun with higher sights in order to cowitness but never bothered to determine which optics, if any, will actually do this.
When the M41 was designed optical sights were pretty much a non-issue and so I don't believe they gave it any thought. Today they are much more popular and I see mostly Aimpoint type optics on them. I'd seek out a 50 foot .22 Competition in your area and get there either before or after the Match to see and talk to the guys who are using them in competition.
The other thing to do is to call Aimpoint and pick their brains.
I know little about them as I do not own one - sorry I could not be of greater assistance.
