[Eye of Unk]

I hadn’t owned a fire arm in over 35 years. Obama’s comment’s about a national police force sent chills down my spine. Recently purchased a 12 ga pump. BTW- the end of the barrel has a little part that can be unscrewed and removed from the inside of the barrel. It’s about 3 inches long. Anyone know what or why or the purpose. Don't believe a word when somebody says its for the silencer. Its for a choke, different types for different shot patterns.

Thanks loads, that is exactly what the piece looks like. So, I can buy diferrent screw in pieces to modify the choke?
