Im looking to get a shorter barrel for my Remington 870 Express and don't have a lot of extra funds as usual.

I was looking at the 18.5 Mossberg barrel for around $115

then i found a 20 inch barrel made by Target Sports Tactical for around $70
I couldn't find anything about them and i an skeptical of the price.

Has anyone ever used one or at least seen one in real life?
