Browning did not offer one, but you may find an aftermarket Hastings barrel (www.hastingsbarrels.com) that will do the trick.
Try e-gunparts.com, Mid West Gun Works, Browning.
Providing it is a Auto5 which wasnt noted, it would have been made in 1929
This gun was made in 1929. The barrel address should say: BROWNING ARMS Co OGDEN UTAH.
It shouldn't say light twelve on the barrel, but on the receiver. Light twelve means that the gun is a light weight version of the standard Auto5 shotgun.
You need to call Browning.
Your serial number indicates that you have a Browning standard auto-5 shotgun in 16 gauge that was made in the year 1961.
Go to Browning.com, click on customer service and look at an Auto-5 manual.
See what they are selling for at Gunsamerica. http://www.gunsamerica.com/ That should give you a pretty good idea.
A rifled slug can be fired from a smoothbore barrel with relative accuracy to about 100 yards. By relative accuracy, I mean that shots can be held in a 5 inch circle. That is about the size of the target zone on a deer. For a rifled barrel, rifled slugs should NOT be used, but sabot slugs can be.
87 years old.If you have a 12 gauge shotgun then it was made in 1906,if your shotgun is a 16 gauge,then it was made in the year 1919.
Located on the barrel or receiver.
