I've owned 3 Sigs in the past 6 years or so and the first one I purchased in 2012 was abysmal. It was an '07 manufacture and it had a damaged barrel and feed ramp. When I brought it back to Wolverine Supplies they went to exchange it and the whole batch of pistols they received were damaged. Fast forward to 2017, I have a Mk25 that has about 1000 rounds through it and it has been excellent. Sig has really stepped up their QC compared to what it was 10 years ago, well for their pistols atleast, I can't comment on their rifles.
