I had purchased another Kick Lite stock at the Gun Show in Chantilly VA back around December. I finally took it out of the package this week and was surprised that I had gotten taken. It looked the same as my other Kick Lite, same package but, the roll pin went thru the back side and it was fixed! There was NO spring and NO spring retaining cap in the end after taking the shoulder stock off. I called Phoenix Technologies LTD in NC. tucked tail, explained my dilemma, and asked if they would sell me a spring and end cap? Brenda @ Kick Lite said NO but, If I send it back to them they would replace the part with a good one! They would rather have a happy customer, shooting with a safe product. They are a family owned company and really care about their customers. That is a rare these days! All 4 of my Mossberg Shot guns will be Kick Lite equipped. GOOD COMPANY GOOD PRODUCT
