I purchased a Mossberg ATR 100 Camouflage 270 for my son two years ago. When we got the gun out last year to sight it in before hunting season we pulled the trigger and nothing happened. We took the bolt out and realized the firing pin had somehow sheared off. Neither myself or my son ever had the bolt out. We contacted Mossberg customer service. They were supposed to send out a pickup order and box for the rifle and we never received anything. We took the gun to a certified gunsmith and he unscrewed the firing pin from the bolt and said to call Mossberg and have them send you a new firing pin and he would put it in. So we called Mossberg and they refused to send us one. So needless to say it will be another season where this piece of sh** doesn't get used. Don't waste your money on one of these...spend a little more and get a real gun. Brian Tharp, 1003 S Main, Rock Port, MO 64482 660-744-2300 [email protected]
