Remington Riveted Extractor Installation Tool
We are now offering the Remington type riveted extractor installation tool. This tool is made off the original Remington factory blueprints for the 30-06 head size & we have added the 222/223 size on the other end, making it a dual purpose tool. One end is marked 308 while the other end is marked 223. These marked calibers are not exclusive, but give an indication as to which head size each is designed for. The 308 size will function for the larger belted magnum cases. This tool will work for the model 700 early riveted extractor in any of the case head sizes of 300 Win, 7mm RM, 30-06, 270, 308, 243, 22-250, 222, 223 etc. It also can be used on the model 740, 742,760,788, 600, 660 & XP-100 in appropriate calibers. This works on both right & left hand actions
This tool is made from 1018 CRS & case hardened to withstand much usage. It is designed to be used in a vise using (2) 1/4"pins inserted into the holes in the base section. These 2 pins will lay on top of your bench vise & after tightening the vise will secure the tool for use.
In use, remove the bolt & strip it down a much as possible, especially the ejector & firing pin. It will now be necessary to remove the rivet that will be still holding onto a portion of the broken or bent extractor. This can be drilled out with a #00 starting drill if placed in a clamped down vise in a drill press or a milling machine. However I have had excellent luck using a Dremel tool & a carbide dental burr. DO NOT OPEN the rivet hole any larger than it is now.
Clean the extractor recess in the bolt head. Before you insert the new extractor, run a file over both sides to remove any possible burrs. This new extractor has to be able to move unrestricted while inside the bolt lip recess to function properly.
You probably will have to squeeze the new extractor together slightly or bend the rivet end slightly to ensure it has spring tension after it is riveted in place. It can be altered after installation IF it is pre-shaped slightly smaller, but very hard to get behind it to bend it inward after riveting. It is suggested that you examine a functioning firearm that is using this same extractor before you start this project. Experience here is a benefit.
In use, insert the extractor into the bolt head recess with the hook positioned appropriately, then insert the rivet from the inside thru both the extractor & bolt head hole, letting the rivet head hold the extractor in place. Position the bolt & extractor onto the appropriate end of the tool & hold it there. Using a small ball-peen hammer (4 to 6 oz. is a good size), peen (rivet) the tail of the rivet into the bolt head. It needs to be tight to hold the extractor correctly. NOTE, if the tail starts to bend to one side of the other, use the ball of the hammer to force it more toward the center & desired location. This hole that you are riveting it into is slightly beveled from the outside, allowing the soft rivet to be forced into the this cavity creating a strong grip. Once it is tight, take the bolt off the tool & if the rivet protrudes any amount, file the excess off to blend with the bolt head.

Inspect the finished product & try a dummy round by pushing the rim straight in, no angling as you want to simulate the firearms operations. The rim may hand slightly on the rivet about 180 degrees from the rivet. If this happens, more than likely the leading edge of the extractor needs to be blended ever so slightly with the forward inner lip with a Dremel tool & a 1/4" stone or polishing point to form a smooth transition. Don't go too much as you may have to do some adjustment as described below.
Try the dummy round again, your goal is for the rim to move rearward & snap under the extractor's spring tension without excessive resistance.
If this works, fine. If not you may have to adjust the off side of the extractor by using a small aluminum or brass punch & tapping the extractor back against the inner bolt recess lip. You can not go far as the spring tension comes into play here. You now may have to now go back & re-polish with the Dremel tool.
Finally when it looks & feels as if it will function, re-assemble your parts & place the bolt back in the firearm. Load the firearm as a single shot using a dummy round. If this feeds, the load the magazine with it's capacity & try the feeding again, operating at a normal cycle rate.
Then as a final check, test-fire a factory round in the firearm & check for extraction.
A word of caution here, if you are working on a model 740 or 742, while you have the barrel off (you need to do this to get the bolt out), check the chamber for rust. If the chamber happens to be rusty, & you have now installed a new extractor, the rust may very well grip the fired case so tight when the semi-auto cycles that the new extractor & the metal lip retaining it may be ripped off the bolt head. And it is about impossible to obtain good replacement used bolts for these guns now-days.
