Improvised Rifle Grenades - Making a Working Weapon Out of Surplus and Scrap Hardware (Paperback, illustrated edition)

Powder guides you through the steps to modify a dummy military-surplus M31 grenade body, pack it full of improvised C-4, affix it to the weapon of choice and let 'er rip! He even includes his ideas on improving Ragnar's original C-4 formula, along with safety tips. Assembling and firing such a device can be very dangerous and is potentially illegal. Therefore, all BATF rules apply.
