Precision-formed carbon steel shims take up the gap and center the bolt body after truing the receiver with the .715" Bolt-Way Reamer. Saves time and effort by eliminating the need to fabricate shims from scratch. To install, undercut the bolt body to accept the shims and solder or adhere them in place with the included retaining compound. Front and rear two-piece shims are manufactured to precise tolerances and pre-contoured to ensure a perfect fit on any .700" diameter bolt body. After installation, machine shims to .7135"-.7145" O.D. to provide proper clearance for snug bolt fit and ensure reliable cycling.
SPECS: Carbon steel, polished finish. Front Shims Nominal .400 (10.2mm) wide x .012 (.305mm) thick. Rear Shims Nominal .700 (17.8mm) x .012 thick. Includes front and rear shims, retaining compound, and complete instructions.

It will do the trick(04/11/2009)
This is a good product, but needs better instructions for installation. The loctite adhesive that comes with the product needs further explanation. Loctite recommends that it be applied to both surfaces. I find that the adhesive holds better when left to set for 72 hours. They also recommend to rough up both surfaces for better adhesion. I used 600 grit on the inside of the shims and bead blasted the area of the bolt where the shims will be applied, tape off the rest of it. If you will be using the shims to build up the bolt for a sloppy raceway, calculate your finished diameter and subtract .020. Under cut the bolt to this diameter. The adhesive does take up a few thousands by itself. The rubber bands work fine to hold them in place. Make marks on the bolt before installing shims. Set shims on bolt about 30 to 40 degrees away the mark. Then rotate them as you apply them to the bolt to line up with your mark. Be generous with the adhesive. The excess that oozes out will not dry and can be wiped off with a shop towel. The setting process for the adhesive is caused by a lack of oxygen under the sleeves. Do not clamp the shims to the bolt, only use rubber bands. This will allow enough adhesive to remain under the shims for adhesion. When turning in the lathe - take small cuts like .001 or .oo2. This seems tedious but you are dealing with an interrupted cut. If you take too much, you can peel them right off the bolt.
If you follow all the rules there will sufficient material left on the bolt and they will do a great job.
One note extra, during the manufacturing of the shims they usually end up with a raised corner. This can be corrected by laying the shim over a round surface and gently tapping the corner with a light ball peen hammer. Also note that there is a little protrusion on one edge of each shim in a pair. Put those two edges together, I believe it is where they cut the shim in half and will keep them mated the way they were before the cut.
