Anyone know what or why or the purpose.

More info than you probably need about shotgun chokes.

If the gun is for home defense, you might wish to remove it, but at in-home ranges it won't make a realistic difference.

Thanks I’ll check it out.

DO NOT remove the choke. Yes there is a reason for doing so, but the same can be had by replacing the choke that's in there with a "Cylinder", which is what it might be to begin with. Essentially a NO CHOKE.

Chokes tubes are marked on the side, with what they are. "Cyl", "Imp Cyl", "Mod", "Full" etc.

Just don't shoot it with out a tube screwed in. You'll damage the threads.
