I just got a mossberg 715 the one with the carrying handle and it has a fixed butt stock. I didn't get a manual and they don't have one online for it. It has holes in the tube just like an collapsible one and it appears to function like a adjustable one but I can't get the pin up that is keeping it in place. Can some one tell me how to lift of the pin to adjust the butt stock also can I just buy the little price that you push on a regular adjustable stock and put it on this one instead of buying a new buttstock. Thanks
