I ordered a 1" OD light Mount-n-slot and QD micro sling mount on Friday. I received my order TODAY via USPS and no I didn't request the faster delivery service. Though I haven't installed the parts on my rifle yet, I will say that they both look and feel to be extremely high quality. the finish on both are perfect and even the packaging is impressive. Eric wrote a note on my invoice inviting my to call if I have any problems or questions.
You don't find many companies these days with this type of customer service and I like to point it out when I find it. Thank you IWC for making my day!
