<p>The invention relates to a training weapon system for a portable recoilless anti-armour weapon of the type which comprises a sub-calibre insert barrel (1) arranged in the bore of the launching barrel of the full-calibre 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-calibre 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 calibre weapon. By such an arrangement it can be avoided that length tolerances give rise to undesired radial 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> |
