Great selection of what I need; the proper buffer and spring combo. Many sites just sell a so called "mil-spec" spring/buffer combo that you have no idea what weight is being used. I know I got a "H" and that it weighs the proper weight for a carbine.
Product was exactly as described. Owner went out of his way to get it to me as fast as possible
Shopping on the site was very easy and the shipping was extremely fast.
