<p>PCT No. PCT/SE98/01021 Sec. 371 Date Mar. 11, 1999 Sec. 102(e) Date Mar. 11, 1999 PCT Filed May 29, 1998 PCT Pub. No. WO98/55820 PCT Pub. Date Dec. 10, 1998The invention relates to a training weapon system for a portable recoilless anti-armor weapon of the type which comprises a sub-caliber insert barrel (1) arranged in the bore of the launching barrel of the full-caliber weapon. In order to improve the accuracy of the system and make it more safe as well as less expensive when compared to previous systems of this type, the sub-caliber insert barrel (1) has a rifled bore to make the training projectile spin stabilized. The forward aligning member (5) for centering the insert barrel (1) is engaging the ridges of the rifles in the rifled portion of the barrel in the recoilless full caliber weapon. By such an arrangement it can be avoided that length tolerances give rise to undesired radical deviations which might result in a mis-alignment of the insert barrel (1) within the gun bore. This could happen with the forward aligning member engaging the conical, smooth-bored firing chamber in the barrel.</p> |
