Czech URG 86 Grenade
FINE ,original black training grenade with its internal frag matrix,
Description
The URG-86 is described as a universal hand grenade in that it combines both timed and impact fuze functions. Both are activated 1.2 seconds after the safety lever is released as the grenade is thrown. After this interval the impact fuze is armed so that any impact with a surface, including soft terrain such as sand, grass and snow, will cause the grenade to detonate. After a period of 3.2 to 4.6 seconds a time function will operate to detonate the grenade.The interior of the grenade body is prefragmented to provide an increased fragment spread effect. The main charge is 42 g of an unspecified high explosive.A training version filled with an inert material but with a fully functioning fuze assembly is known as the URG-86-Rd. There is also an inert training version with a functioning fuze containing no explosive elements, known as the URG-86-Sk.
