yes , i have done this, i couldn't find a 3 inch slug barrel so i put on a 2 3/4 inch one and it worked fine, but Remington said no, guess that's their liability answer.
It will fit on the frame but the action will not function with 3 inch shells.
The barrel may be able to be fitted however the shotgun would still be limited to 2-3/4" shells. A longer stroke of the bolt is required when shooting the 3" magnum shells which requires a different receiver. Not the best idea.
The difference is that the Remington 1100 3 inch mag will take three inch mangnum loads and shorter where one that doesn't say 3 inch on the barrel will only take two and three quarter inch shotshells or smaller.Trying to put a three inch inch a gun that is not designed to will cause extreme stress on the barrel and will get jamed in a pump or automatic shotgun.
All day long. Any shotgun can handle shorter shells than it is chambered for as long as they are the same gauge.
no. amphibians have three chambered heart i.e., 1-A 2-V
No. Humans are mammals too, and our hearts are 4 chambered.
yes.
About $400.
A three chambered heart has two atria and one ventricle. Only amphibians and reptiles have three chambered hearts.
about 1873...........................
Yes but not the other way around .You can not use 3" shells in a 2 3/4 chambered gun.
If you want to know the month & year your rifle was made send me the two or three letter code stamped on the left side of the barrel back by the receiver ring.check the date code stamped on the barrel. Remington Society of America, Manufactured Date link has the details.
