RE: ported vs non-ported choke
I shot both the TruGlo Gobble Stopper ported choke.
And a Hunters Specialties The UnderTaker.
They both patterened about the same.
The recoil was the same.
The UnderTaker was about $7 cheaper
And did patteren a little better in my gun.
GO to a local gun shop and ask them about
People that use the Rem 870 and
What choke did better in it.
It will probbly do about the same in yours.
But the best way to find out is to get both and shoot them for youreslf.
What ever you do be carefull and remember to use ear plugs
GOod Luck
