At last, the mortar prototype is finished. The shells are steel tube and based on (though not replicas of) the SMBL 2″ mortar shells. The six fins and band at the top hold it straight as it is dropped into the barrel.
Inside you can fit a TAG shell or other 40mm grenade. To recharge them, simply remove the tube, reset the firing pin if needed and re-gas. The tube is held in place by the spring tension of the bottom half, these are taped up for dispatch.
Time for some pictures:
Although the early models were supplied with an adjustable sight for targeting at different ranges, these were quickly ditched in favour of the single white line up the back for quick lining up. Adjustments could be made by eye.
This picture shows how the shells come apart to fit a 40mm grenade or TAG shell. The top half just pulls out of the bottom, held in place by spring tension. The shell on the right is taped up ready for dispatch, this isn’t needed for use.
When loaded, these are very safe to carry. MOSCARTs are notorious for going off when dropped. These shells have a firing pin which is recessed well into the tube which reduces the chance of this happening-prarticularly important when using TAG or solid state launchers.
