Does this fit Cricket chipmunk ?

If you are using the Crickett® or Chipmunk® Rifle Scope Mount Kit it which has a 3/8 dovetail this adapter may be 1/16 of an inch too wide to securely clamp to the rail. Manufacturers tend to round rail widths, I this this will work. Worst case a small shim could be used to bridge the gap.

Will this fit on a crosman 357 snr?

I do not believe that the crossman 357 snub nose pistol has a dove tail rail. The owner's manual does not make mention of this and the rail is not called out on the photo graph of the pistol.

Day 2 on a next day delivery for prime. still hadn't shipped. bait and switch game with smazon.

Shipping delays can occur - with the current shipping company labor action on the horizon 2 of my orders in the past two weeks (12 items total) were delayed. Annoying but Prime is still far better than other vendors for next day deliveries.

Will this fit a Molson nagant

My gut is telling me no, however while I don't own a Molson I know someone who does, and he has an adapter on it, which is also a universal Picatinny Rail(also no). If you have a Archangel M-1891, I would also say no it won't fit. This is probably meant for small rail set-up like BB gun or Sidearms.
