You will need to change barrel's, a accu choke is not on a slug barrel.
Depending on condition and completeness, anywhere from $100-$225. Frequently these are missing the rear sight (removed to install scope) and the sights are pricy to replace. There IS a Mossberg Collectors Association- check havlinsales.com for more info. For general information on Mossberg 22s, Google "epix mossberg models". Nice rifles.
Raise the bolt arm, slide to the rear. Press the trigger and the bolt will slide part the lock and can be removed.
I don't know why someone would completely not answer you. You asked about the 600ct correct? So to know about the AT really isn't much use to you. Yes it is the same as the Mossberg 500A!!!!! It was a model created for a store brand to identify which chain was selling the item. All parts and fubctions and shape and size is identical to the 500A. The only difference is that it had a 1/2" shorter barrel than the 500A due to the full chokeAnswerThe Mossberg (New Haven) 600 AT is essentially the same as the Mossberg 500. The differences are the 500 has a firing pin spring, and the action bars on the 600 can only be removed by removing the magazine tube. AnswerThe Mossberg 600 AT is the same as the 500 with two differences. The 500 has a firing pin spring, and the action bars on the 600 can only be removed by removing the magazine tube.
make sure gun is unloaded (of course) & squeeze trigger while sliding bolt back, it will slide right out... squeeze trigger to replace bolt also.
There is modest collector interest in Mossberg rifles from that period. Value will depend on EXACT condition, and completeness (many had rear sights removed to add scope- replacing them is pricy.) Prices for very good, complete, range from about $125-200.
You need to remove the recoil pad. Once the pad is removed the stock is hollow. You need a long flathead screwdriver to remove the one bolt holding the stock on. Shine a flashlight into the stock and you'll see the bolt easily.
It will not be removed.
Yes, rust can be removed.
The nephews of your first cousin once removed, like the children of your first cousin once removed, are your first cousins twice removed.
The children of your first cousin twice removed are your first cousins, thrice removed - or three times removed.
