I have taken my Garand and recently my M305B bolts apart by hand, putting them together is even more fun, bust fingernails and blood blisters. I have also used the stock tool kit with less flying pieces. Good thing to learn if you are in the field. I found a Brownells bolt tool on ebay, so I went for it. What a complete blast. I was taking the bolts apart and putting them back together in seconds. If you can get one of those tools, get it. One modification that I did was to polish the pin that moves the extractor out, it had a sharp edge that I didn’t like. Defintely recommend any kind of bolt tool.
