Bests & Worsts Reviews from Amazon

The first reviewer must be the author himself. This book is for someone with a death wish. Quotations below are from the book. First, the author makes no attempt whatsoever to discuss the legalities of silencers. Silencers are legal in 36 U.S. States and a BATF Form 1 must be filed and a $200 making tax must be paid to the Dept. of Justice, BATF & E. in Martinsburg, WV. Only after the approved tax paid Form 1 is received from BATF can an individual begin to build a legal silencer otherwise you are subject to a $250,000 fine and 10 years in Federal Prison for an unregestered NFA weapon. Secondly, the silencers designs are no where near military grade not even for a 3rd world country making improvised weapons in the midst of a civil war. They are circa 1970's baffle technology. Far more important & worse, the materials specifed are grossly unsafe. For example, the .223 silencer design starts with chainlink fence post for the outer tube. No sane individual would ever use seamed tubing for a silencer that is required to contain the pressures associated with a center fire cartridges let alone a tubing that has NO structural rating whatsoever. In addition, the wall of such tubing is too thin to endure the heat that must be dissapated by the silencer. Heat plus high pressure, well we've all chewed bubblegum, and blown bubbles. In addition, the tubing is galvanized and a structually safe weld cannot be made on galvanized material without removal of the galvanized coating. The author specifies soft automotive freeze plugs for the baffles. Next the author specifies "special hole punching ammo" to bore the baffles. This ammo is made, in the case of the .223 silencer by taking a standard .223 cartridge and removing the projectile "with pliers" then dumping the powder out, "raking it into a line cheech & chong style", dividing the powder into fourths and placing one forth of the powder back into the case, reinsterting the projectile "and crimping it in place with pliers". Then the silencer is installed on the rifle, wrapped in a towel, and the round is fired "into a block of wood" so as to drill the silencer concentric to the bore axis, or kill the builder with shrapnel, flip a coin. To make matters even worse, the author specifies 2.5" muffler pipe (seamed non structual) for a .50 BMG silencer!! A Lincoln "Buzz Box" is the welder of choice for silencer construction. The book is not even usefull as reference material, best to stick with the series by Alan C. Paulson for a technical reference. There are far better examples on the internet of quality designs along with the legal guidelines neccessary for building a silencer.
