40x46mm Rounds AR-407 TP/TPM/TPM-T Target Practice / Target Practice Marking / Target Practice Marking Tracer
NSN: 1310
The 40 x 46 mm Practice Grenade is intended for practice firing at distance of up to 400 m. The projectile is inert and contains no explosive.
This grenade is available in three different modifications based on customers needs:
- Target Practice TP – AR407 with Inert Projectile.
- Target Practice Marking – AR407M2 Target Practice Marking Projectile.
- Target Practice Marking Tracer – AR407M3 with Impact Marking Tracer Projectile.
The grenade is fitted with distance-armed, self-destruct fuze.
Self-Destruct grenades have a huge advantage as they will explode within 14-19 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.
