Most likely the best you can hope for is that they'll make sure the gun works before they send it to you. I doubt very much that they'll shower you with gifts by way of an apology much less even sending you a note saying sorry for sending out a buggered-up firearm in the first place. The problem is they are so busy fixing their own Fk-ups they don't have time to be writing letters of apology uch less sendign out a batch of goodies for every gun they have to fix.
This kind of thing happens all to often with century but generally they are pretty good about fixing their own F**k-ups and doing it with a reasonable turn-around time. Century's problem, #1, is that they deal in a huge volume of guns needing to be cobbled together from parts because of ASININE BATF Regs, and this will never stop until we elect a majority of conservativee Republicans who will take action to both reform and de-fund the BATF. All a Democrat majority can ever be expected to do is to support more regualtion and increased funding for that rogue agency.
And #2, in addition to the above, there aren't enough expereinced gunsmiths to do the work and this is in part because gun nuts like ourselves are shy about supporting our local gunsmiths and as a result of that in addition to all the ever-increasing BATF BS that gunsmiths have to deal with, the trade is dying out and fewer people are going into the business, and that's why Century has no choice but to hire inebriated simians to assemble their guns
