I have an old Mauser 96 in 6.5X55 that shoots great, with the appropriate load. However, the trigger is an old two stage military trigger, which I do not like. Do any of you know of replacement triggers that would be available for a Mauser model 96? I am looking for a a crisp, one stage trigger, that fires at about 3.5 pounds of pull. What would be the cost, and how difficult would it be to get the replacement done?
