I placed an order for some 10/22 parts (no mags, though) at ShopRuger.com on 01/15, and hadn't heard anything. Called them today and spoke with someone (yes, they're answering their phones again...) who advised me that they are still absolutely swamped, but assured me that my order would be shipped out by the middle of next week.
My impression is that they're shipping everything out ASAP, but that mags are taking an especially long time.
