40x53mm HE-SD

40x53mm AR-383 HE-SD /Marking for local Bulgarian Market/

High-Velocity High-Explosive Grenade with Self-Destruct

40x53mm High Explosive Fragmentation Grenade with Self- Destruction is intended to defeat enemy troops in open terrain at distance up to 2 200m.

The grenade is fitted with distance-armed, self-destruct fuze.

Self-Destruct grenades have a huge advantage as they will explode within 22-26 seconds even if they have not exploded by the main fuze.

In situations where the grenade hits an object at a certain angle and does not explode on impact, the fuze will detonate the grenade within the certain timeframe anyway. This is very important as if an active grenade remains on the field, it can injure friendly soldiers or civilians.

The ammunition is safe in storage, handling and operation and ensures the reliable performance of the grenade launchers in all weather conditions.
