Well you should be able to purchase an extra replacement choke tube eqiuped barrel for it, but it WILL NOT handle 3 1/2 in loads as your gun isn't designed for them.(1100's were never made for 3 1/2's) Depending on weather or not its a 3" mag version you may not be able to use them either. I would contact Remington and ask if it's a magunum reciever, you will need the serial number for this. I would imagine if the oringal barrel is marked 2 3/4" its not a 3" mag reciever and you will only be able to shoot 2 3/4" shells no matter what barrel you have put on it, in fact I think 3" chambered barrels won't work with the 2 3/4" recievers.Gumbo said:Yes, it's fixed choke. How do you measure the official length of a barrel? From muzzle to what point? The farthest point or to the chamber (like where the shell seats)?
Also, can I get a new barrell for this Rem 1100 that supports 2 3/4, 3, and 3 1/2 inch shells and that also supports screw-in choke tubes? The current barrel only supports 2 3/4 inch shells.
I'd like to get one good waterfowl barrel and one good upland barrel. Or one that could be used for both. Any recommendations would be appreciated.
