I have a question about the recoil reduction system that is optional with Nova pump. Is there a spring that is supposed to be placed inside the bracket along with the weight? I've shot the gun with and without the weight and it just doesn't seem to "reduce" the recoil at all. I haven't seen a spring for sale and I don't recall the instructions making any mention of one, but the imperceptible recoil reduction made me think I was missing something. Any help would be greatly appreciated.
Also, I saw that a cantilevered barrel was offered and I was wondering how that was advantageous.
Thanks in advance to any responses!
