We were looking to see if they made an aftermarket DBM for a model 7. We kind of knew first that we might have some problems with COAL. That is why I asked some questions to see if anyone had done it. We have never done a model 7 yet we have a couple 17 fireballs that we are waiting for shilen barrels to get here and they are model 7 actions that we accurized. Maybe that was a bad idea also, but guess we will find out. Like I said we just wanted to see if anyone had done it and if it worked out. HAPPY HUNTING
