For accuracy testing, I headed out to the range with a selection of Black Hills, Federal and Winchester .223 Rem. ammunition. During firing, the accuracy of the Classic proved to be quite good. I did note a tendency for barrel heat to affect accuracy. The red-dot sight and the diopter rear sight unit worked well, with the iron sights co-witnessing nicely with the electronic sight.

Over the course of a few hundred rounds, there was not a single malfunction. I also noted the Classic had one of the softest perceived-recoil impulses I have experienced with a .223 Rem. rifle, with it being a gentle wave rather than a sharp spike.

Avoid the severe sticker stock of purchasing an original, pre-ban SG550. For shooters who don't mind owning a close copy of the Swiss classic, the new SIG Sauer SIG556 Classic should make a terrific addition to their collections.
