Question for all the old pro's out there,

I recently bought a Browning B-80 from a online auction. I took a chance as the pictures showed an actual "excellent" condition.

It is specifically a 12 guage 2_3/4" model with a vented rib.

The gun showed up in "excellent" condition as advertised, but there seems to be a problem that existed from the factory. My instinct tells me why this thing has had less then a box of ammo threw it in the last 39 years.

The problem is with the barrel how far it moves into the receiver. The barrel obviously has it "home" in the receiver that it must sit inside and be pushed all the way in.

The forend of a semi auto, serves the purpose of holding the barrel tight inside the receiver while firing.

The shotgun I have, with the forend nut tight, still has about 1/16" movement back and forth. I am not talking about the forend loose, it's tight and does not juggle at all. The movement is all in the barrel that can move back and forth while everything is tight.

Do forends have to be fit to the gun to prevent this?

Is this a replacement forend, that purposely came to big, to accommodate fitting by a gun Smith?

Is there a way to adjust the "headspace" when it comes to this.

This is basically a copy of a Beretta A301 - A303, so the knowledge base still applies for these guns as well.


Cheers
 
From Shotgun World:

I would bet that the gun is equipped with what Browning called a "recoil adapter", which is a flat metal shim attached to the front of the receiver and held in place by the two forend guide screws. The purpose of the recoil adapter is to help the gun to cycle lighter loads (it is questionable whether it works or not - maybe it might help a little). With a recoil adapter in place, and when the bolt is open, the barrel feels loose - it will move back and forth a little bit. THIS COULD BE THE ISSUE.

Go to the Brownell website or possibly Browning for an exploded parts drawing and compare to your gun to determine whether something like a small ring is missing from your gun. The original owner may have inadvertently lost a part when assembling/dis-assembling the gun.
 
Madtrapper143 for the win.

Thank you, I appreciate the knowledge.

It is 100% the "recoil adapter" it causes the forend to not seat completely giving the barrel some play. I dont know how that helps but if browning has it in there, it must do something.

Just glad it is not out of spec. One of the weirdest "mods" a factory has done that I have seen.
