im looking to add a match grade 20" barrel, match trigger, bolt handle, choate stock, and some other goodies to a rifle i just got. need some help on where to pick up quality parts that wont break the bank (money isnt too much of an issue just dont wanna wind up paying top dollar for junk). also my 116 has the internal mag with no floor plate and im looking for a conversion kit to make this a detachable mag or floor plate. thanks in advance i need all the help i can get
