Abstract: A bullet trap device for launching, by firing a live bullet, ammunition such as a grenade having a trailing tube to impart thereto a flat trajectory of fire, includes a body to receive the impact of the live bullet, a supporting piece for positioning the body within the trailing tube of the grenade, and a shock absorber part positioned axially between the body and a portion of the supporting piece. The body and the shock absorber parts are formed as an integral, one-piece, solid-forged assembly. A centering ring, separate from the supporting piece, is positioned radially between the shock absorber part and the supporting piece, thereby maintaining the body and the shock absorber part centrally of the axis of the trailing tube of the grenade after firing.

Abstract: This hand grenade comprises a timer for preserving the user's safety when throwing the missile by breaking the pyrotechnic train of the fuse a stabilizing system utilizing the concurrent effects of a weighted ogive and a spread-out empennage adapted when released and operative to brake the missile by aerodynamic effect, thus improving the efficiency of the missile when striking with a low incidence a horizontal surface such as the roof of an armored vehicle. The fins of the empennage are released when removing a safety pin, thus causing the missile to be stabilized in a substantially vertical axial position.
