AT3 Tactical RD Red Dot Sight – Optional Picatinny Riser Mount for Cowitness with Iron Sights – 2 MOA Red Dot Scope, black

Q: Will this hold up on a mossberg 930 spx 12 gauge autoloader?

It was good on my Mossberg 500 using slug

Q: Will this work with a Smith and Wesson Victory?

If it has a picatinny rail it will mount... How you use it, dunno that gun but this is suited to rifles and shotguns... Wouldnt personally put it on a handgun

Q: how many MOA per click of the sight adjuster screws?

The stated specs are 1 MOA for both windage and elevation. I've sighted at 25 and 40 yds but did no formal measurement. Zeroed easily without too many clicks.

Q: Is this made by primary arms?

No. It's made by AT3 Tactical, a totally different company. I happen to own a scope by Primary Arms, and it is excellent. But the AT3 Tactical RD-50 is just as good at half the price. And their telephone and e-mail support is second to none.
