Sinclair AR-15 Action Cleaning Link: Does exactly what it is designed to do & easier to use than competitor's links. Although I had several items in my cart the shipping cost became prohibitive with each item I added. I ultimately removed all items except this one item and shipping was the same cost as purchasing the cleaning link., ~ $10.00 each. I purchased the items I had removed from Amazon.com saving the shipping costs. Too bad, I was hoping to be able to support a smaller company but cannot justify the expensive shipping to support this company.
