  1. US SIG 556s already have aluminum lower. Looks like they’re just sending the concept back to Switzerland. With the ambi mag release from the SIG 522. For once we got some things first. I’d still like their buttstock though, and the 4-position gas system would be nice for people who run suppressors.
