Gunsmiths over here report problems with the Sig. FTF and breakage issues. Sigs make great handguns, but their rifles not so much. Look at HK, they make the best AR platform on the planet. HK MR in either .223 or .308. One gunsmith told me, why settle for a Sig when you can have an HK (in regards to rifles). My next purchase will be an HK MR .308. I rather wait a little longer to save up for an HK, then settle for the Sig Patrol.
