Mossberg why? - Dead Ringer 3-9x40 Scope

Recently purchased a Mossberg Patriot chambered in 450 Bushmaster. Scope is blurry and horrible. Was able to sight in around 50yds so could use for opening day. Didn't expect much for a scope of this price point but did expect it at least to be clear. Reached out to Dead Ringer to see if they will at least replace, but looking over all the reviews the product is just trash. Shame on me for not doing more research on scope. Mossberg what were you thinking? Stay away if your looking at this scope.
