I am buying a 300 WM Sendero this week and have a few questions. I am pretty smart when it comes to building things, doing it yourself. Does anyone have the name of a gunsmith in the Reno/Carson area they would recommend? I would lake to replace the standard magazine of the rifle with a removable 5 round clip. Any input on what type to buy/where to buy and cost? Can a guy do this himself or do I need a gunsmith for this? I would like to replace the trigger with a Jewel as this seems to be the trigger always talked about on this site. Is this needed? Can a guy buy the trigger and replace it himself? What is the thought about putting a muzzle break on this rifle? Is it needed? I imagine there are are a few different ways/styles to machine this. Is there a preference? I sure appreciate the help with this.
