      Required Materials

      Bedding Compounds:
      Today’s shooters have a plethora of fillers and compounds that will work for glass bedding. Some are high-tech and some are elementary. It is up to you to decide which one you want to use. The favorites are usually
      - Marine-Tex
      - Bisonite
      - Devcon steel putty
      - Brownell’s Acra-Glass and Steel Bed compounds,
      - PC-7 steel epoxy
      - And surprisingly, even JB Weld!

      I am sure there are others out there but those are the choices most common when bedding the M14. The key is that you want to use one which is very hard. Soft epoxies will have a short bedding life. Another thing to consider is the ease of use. Marine Tex, Devcon and Bisonite all have to be mixed to exact proportions. Some compounds are more forgiving and easier to mix; like JB Weld and PC-7. The more sophisticated epoxies will run anywhere from $50 to $100. JB Weld is cheap and so is PC-7. Pick what is in your budget but be prepared for the drawbacks. I just swung by the local boat shop the other day and found a jar of Marine-Tex for only $45. A future purchase is in order.

      Release agents:
      This has proved to be my most frustrating item to track down. Good industrial stuff is hard to find (at least for me). I did some research and found that Brownell’s sells some stuff called T.F.E (http://www.brownells.com/aspx/ns/store/ProductDetail.aspx?p=1155&title=T.F.E%20DRY%20LUBE%20&%20MOLD%20RELEASE) and also another product called Acra Release (http://www.brownells.com/aspx/ns/store/ProductDetail.aspx?p=1045&title=ACRA-RELEASE?)

      I recommend you shy away from the TFE as it does not work really well on M14 bedding. I had epoxy stick to my receiver while using this stuff and half of my bedding and some wood ripped out when I removed the receiver from the stock.

      A lot of shooters use Kiwi shoe polish or Johnson’s paste wax. These work really well as a release agents but they are somewhat thicker and may produce a loose fitting glass job. I suggest a thin spray-on type of release agent that will allow the thinnest barrier between the rifle and the bedding compound. Gus Fisher recommends Valspar 225 or Ram 225 but I had to e-mail Valspar to get distributor information. I was contacted by a company called Sher-fab (http://www.sherfab.com/) in Norwalk, CA. They have Valspar 225 in spray-can form as well as in jars, buckets and pails. Be warned that it is expensive.
      I did read one suggestion that Hornady One-Shot bullet case lube works really well. I happen to have a can of this and I will try this on a junk 22 rifle and let you know how it all works out.
