Remington SPR 453, which as you probably already know is a Russian made shotgun based on the (Baikal MP153). I bought one before duck hunting and love it. Below is a list of pros and cons.
Pros:
Absolutely bullet proof. There is a video on utube that proves that. Search for it on utube and you will be amazed.
Shoots well for what it is.
Shoots 3 1/2 to 2 3/4.
Inexpensive for an autoloader.
I believe you can get one in camo now as well.
Cons:
Needs to be thoroughly cleaned out of the box.
Does not look pretty.
Follow break in procedure or it may jamb.
loading shells can be somewhat hard on your fingers as the tube is pretty stiff.
Overall for the $$ I would say it is a great gun.
