I had a 870 and wanted to to get a 18 1/2" barrel for it. But looking at prices realized I could get the H&R or a Maverick88 for just a little more. The H&R is a Chinese copy of the 870. And the Meverick88 is based off of the mossbergs. Since I have a 870 I went and got the H&R. I have shot about 200 rounds through it and have not had any problems. I have also heard that the Maverick88s are really good as well.
I got mine for 180 out the door from Cheaper than dirt. Since I live by their store I picked it up there, so no shipping or FFL transfer fees.
I really am happy with my purchase and would not hesitate to do it again.
I agree with the above post. When i was in the market for a cheap HD shotgun, I choose the Maverick and believe the price was $200. I have been happy with the mossberg. I think either one will suit your needs!
