The 555s have a lightweight alloy receiver, Turkish walnut stock and forearm, a single selective trigger, extractors, and a manual safety. They come with five interchangeable choke tubes. That’s all standard stuff. You won’t find added details and options you will find on a higher-end over/under. This is like the base model—you can pay more for alloy wheels and heated seats, or you can pay less for one that does everything without the frills.
