Abstract
A boresight verification device (BVD) comprised of a circular housing with a rear portion of smaller diameter and a front portion of larger diameter. The front portion securely holds a level. The circular housing also contains a plurality of spring plungers which grip the inside of a muzzle when BVD is inserted into a muzzle for use. A tooling ball provides a stable reference point.
Claims18
A boresight verification device for aligning an internal bore of a barrel muzzle for a mortar to an external aim sight, said device comprising:
- a cylindrical housing including a front portion to extend beyond the muzzle and a rear portion for insertion into the bore, wherein said portions connect together in tandem along a symmetrical axis of said housing, said rear portion has a smaller diameter than the bore and also said front portion, and said front portion has a recess opposite said rear portion;
- at least one level secured transverse to said symmetrical axis within said recess in said front portion of said housing, said level presenting visual verification of orientation perpendicular to vertical direction of acceleration;
- a plurality of securing components symmetrically disposed around said rear portion, said securing components engaging the bore;
- and
- at least one indicator extending radially beyond the muzzle from said front portion to present a visual reference to the external sight in alignment with said rear portion.
A boresight verification system for aligning a mortar to an external aim sight, said system comprising:
- a barrel muzzle for the mortar, said muzzle having an internal bore;
- a cylindrical housing including a front portion to extend beyond the muzzle and a rear portion for insertion into the bore, wherein said portions connect together in tandem along a symmetrical axis of said housing, said rear portion has a smaller diameter than said bore and also said front portion, and said front portion has a recess opposite said rear portion;
- at least one level secured transverse to said symmetrical axis within said recess in said front portion of said housing, said level presenting visual verification of orientation perpendicular to vertical direction of acceleration;
- a plurality of securing components symmetrically disposed around said rear portion, said securing components engaging the bore;
- and
- at least one indicator extending radially beyond the muzzle from said front portion to present a visual reference to the external sight in alignment with said rear portion.
