Based on my brothers I would stay away from them. His had poor QC, so the bolt was messed up and the extractor as well. Would jam on him all the time. He has taken it to a gunsmith twice. He also found that the bolt was made of a soft metal as well. I don't have all the details, but I would not hold his up to a Remy 870 express. Maybe it was a single lemon, but I don't trust 'em.
