No
Yes, it can be changed.
To remove the barrel choke on a Mossberg 600AT shotgun, first ensure the shotgun is unloaded and clear. Use a choke wrench or a suitable tool to unscrew the choke from the barrel’s muzzle. Turn it counterclockwise until it is completely free. Once removed, you can replace it with a different choke or leave it as is, depending on your preference.
no but it will fit a mossburg 500
Yes, it is. The 600AT was simply sold under the New Haven name instead of the Mossberg brand. It's a Mossberg 500A (12 gauge) intended for targets and hunting (long barrel and great wood). All Mossberg 500 parts fit it.
You will need to change barrel's, a accu choke is not on a slug barrel.
Most firearms have the model number/name stamped on the receiver or barrel of the firearm in question.
Really doesnt matter which model, I guess. No more than $200.
$175
Mossburg. The Mossburg Model #346
Yes there is: there is one made by S&W (~$150) and another made by Mossburg (~$120) - I've seen both on Gunbroker.com and both were smooth barrel open sights with a 3" chamber.
