I am about 3/4 through The Terrifying Three by Dincan Long and I must say this is one well written book. It covers Uzi, MAC and Intratec firearms. It is well written and is an easy read. Duncan Long really goes into detail on how all 3 were formed. He explains all the different models in great detail and the last half of the book is devoted to cleaning, ammo, supplies, accessories, etc.. I would highly recommend this book to anyone interested in learning more about MAC's. The author has also written many other books on everything from Glocks to reloading and I am looking forward to reading more of his offerings.
