Need help to Identify a REM 12GA Barrrel

[tobyjugg]

I need help in Identifing a Remington 12GA barrel I purchased at an estate sale. The barrel has the usual Remington marking on one side and is marked 12GA for 2 3/4 or 3 inch shells on the other side. It is vent ribbed with a white bead front site and a middle of rib silver bead. It is glossy and is REM CHOKE ready. The part that slides over the shell tube has what looks like a spring or clip on the front. I think it is a Rem 11-87 Priemier barrel but not sure! Your help would be appreciated. Thanks Tobyjugg
