In addition to its impressive performance, the .338 Spectre is also relatively easy to load and shoot. With a quick trip through the sizing die, shooters can have their brass ready for firing in no time.

Overall, the Complete Upper Assembly .338 Spectre is an exciting new option for tactical shooters who want a powerful and versatile cartridge that can be used in a variety of firearms platforms.
