Yes i am sure the choke tube is made for the remington 870. It is model TG150 on the tru glo strut stopper and it used to fit in my 870 I had 2 years ago. I dont know whatr the problem is but Tru glo wont take it back and look at it since it is 2 years old.

I guess I am going to have to eat it and look at the ventilator since it is cheaper.

Thanks
