I don't have any expeirence with that model but.....
I have a 144LSB (Lyman peep rear and globe front sights)that I plan on keeping at least until I get a US marked 44 or 144 to replace it.(I may keep it even then if funds allow as it was the first "target type" 22 I bought).
I have a 320 with a Mossberg peep sight and a dual post blade and ring front sight.I relined the barrel on that one and they both shoot great.
Look at the front sight base on the 46.If it has a screw in the side,it may have the dual front sight.Turning the screw 1/4 turn will rotate to the other type.
Short answer,I'd like to have it!
