How do you disassemble a browning centerfire semi auto hunting rifle?

If we are talking about a browning model BAR?There is a book published by J.B.Wood entitled the gun digest book of firearms assembly/disassembly Part IV.This book is invaluable to the home gunsmith,firearms owner for the proper care of your rifle.On page 19 you will find the complete step by step disassembly of the browning BAR.I have used it many times and have copied the pages for others that own a browning BAR.It also covers the tools needed.Good luck.
