Reading another post about M-48 tune-up, I sent my M-48 back to Nosler and also had them refinish the stock, MAJOR improvement, they also went throught the rifle and check things out. They changed the trigger from the timney to ?. I had some work done on the original trigger and I guess because of liability reasons they could not send the original one back with the rifle. The jury is still out regarding the new trigger, I will wait till I shoot again to make a final decision to see if it is better than the one I had. Does anyone know what the new style trigger is? Anyway THANK YOU NOSLER, you are a top notch company and provide excellent products.
