Cruzer,
I wish I had known about the Ultradot before I ordered my Leupold, but I'm sure it will work fine once I get the adapter. BTW, I asked Larry about the availability of a 6" Target model, for unscoped silhouette match shooting. The standard 4.5" Trailside is great for plinking, and I'm sure even better with a scope, but the sights are awful. His answer was: no luck. He said he hardly ever gets them in, and has NEVER received a competition model. I would think Hammerli would ramp up production to meet demand.
Oh, and yes, I am a geologist.
