It contained about 200 grams of explosive charge (TNT) in a cylindrical can. The grenade could be thrown about 35-40m and has an effective blast radius of about 10m. The total weight of the grenade with the fuze was about 500g. It used the 3.2 to 4 second UZRGM fuze, also used in the RG-5, RG-41, and F1 grenades.
