    Ok,

    This is for anyone not sure how to take apart there bolt for cleaning on a Remington 700ML. This should be done, everytime you clean your 700 ML. This really needs to be done after a range session or after a hunt. Even though the bolt is sealed, and away from the powder -you still get blowback, that can end up inside the bolt, from cocking it when the plunger/firing pin is dirty with fouling. Failure to do so, will cause you issues.

    There are a couple ways to take the bolt apart-the easiest is to use a Bolt Dissassembly tool. Remington sells these. You might even find them through Brownells. EVERY Remington 700 owner, both centerfire, and muzzleloader version should own one of these to service, and clean the bolt assembly. The centerfire 700 tool comes in a double sided version -one side is for short action 700's, the other for long action. The one in the pic is for a short action only but works for the ML!.

    1. Here are the tools you will need. A 700 Dissassembly tool, and a 5/32 Allen wrench

    2. Make sure your 700ML is unloaded!! Confirm this before continuing. Make sure there is no cap/209/ in the nipple. Put the safety in "S", and lift the bolt, and pull it back. Unscrew the allenheaded hold down screw with the 5/32 allen wrench. You do not need to remove it, just loosen it enough to remove the bolt assembly from the back.

    3. The bolt assembly is now ready to be disassembled. Note the position of firing pin head in the detent of the bolt body. This is the position that it will need to be in, to properly fire, and to install back in the rifle. Also note the top of the bolt (plunger/firing pin end) the plunger that comes out out and smashes the cap, or 209- is pulled in (cocked!)

    4. Next, you'll need the disassembly tool. Look at the opening in the tool, you will see a notch cut out. You slide the tool over the end of the bolt. The firing pin head slides through the notch of the tool. Make sure the bolt is all the way down in the tool. Grasp the tool by the knurling, and rotate the tool 180 degrees. This will keep the bolt spring pulled back, when you disassemble/reassemble. Make sure the tool does not spin off causing the bolt to unspring. It can be a real bitch to compress the bolt if it does.

    5. Now comes the actual disassembly. Grasp the bolt by the back half (do not grab hold of the tool!) and unscrew it by turning it left.

    6. Below is a pic, of the bolt assembly disassembled for cleaning. You do not need to go further then this to take it apart for cleaning, and lubing. Be sure to LEAVE the tool installed on the back at all times. The insides are ready for cleaning. To clean the inside of the bolt body (the part with the lift handle), run SCALDING hot water through it, and flush out any fouling. Use a brush to aid in cleaning. Test tube brushes work well for this. Dry thouroughly, and relubricate. The spring assembly, can be flushed out with a spray degreaser. Be sure to to dry thoroughly, and relubricate. On the end of the firing pin - the sides of the plunger usally is the area gets corroded, and causes problems. If it is rusty or dirty, dress it with fine steel wool, until its clean. I lubricate that area with Bore Butter, as it is exposed to fouling from Black Powder/Pyrodex. I have never had a single corrosion/seizure issue doing this!

    7. Once you are done cleaning, and lubricating - its ready to go back together. To assemble you will screw the 2 parts of the bolt together. When you go to screw it in, grasp the back of the bolt above the tool - not by the tool (see pic below) Once the firing pin head is all the in the detent, you may unscrew the tool, by turning it 180 degrees to the notch, pull off the tool and reinstall the bolt assembly back into the rifle. Lock down the allen bolt, into the cutout groove of the bolt.

    Hope this help anyone who is reluctant to clean out there bolt on the 700ML. And in case you have lost your manual, attached to this post is the factory owners manual in PDF format.

    Thanks for the info.I just became the owner of an almost new gun that had the 209 primer conversion already done.I quickly figured out that a 28ga Remington shot shell cut to length made a great shroud.
