Takes apart the same way a 700 bolt does. The bad part is, it doesn't have that little cutout to put a dime or something to hold back the spring. You need a special tool that browning has or specialized service shops that will go in and hold the spring tention until you can screw off the holder.

I used to worry about it, but don't anymore. Just don't pour gobs of oil in it every month. In fact just wipe it down with an oily cloth. I have taken apart 700bolts and others that were fairly old, and you would think someone put bearing grease in there, with the years of different owners, and various types of oils with the fouling and dirt gunking it up. I don't know why folks insist on pouring one ounce of oil into every working part.
