Hi George! Thank you for taking the time to leave a review. We're thrilled to hear that you're happy with our Magnetic Sling Lock. We understand your concern about having to purchase it separately, which is why we offer a Universal Kit that includes all 3 of our magnetic locking options. This way, you can mix and match to find the best fit for your specific bow model and setup. We also offer the products individually for those who already know their preferred option. Please don't hesitate to reach out if you need any assistance in the future. Wishing you a Merry Christmas!
