That's a recoilless rifle tho
anti tank rifles don't fire explosives
@Dead8plus10Memer, buggy*.
I suggest replacing the Molten SING with SNOW (SING) so as to ensure an explosion per fire. Molten SING explodes when it's temp. is relatively close to 0.00 C and below. But when it is heated, something likely to happen due to nulcear explosion heating everything up, it will not explode due to its inability to cool down to the actual SING. SNOW (SING) is the opposite in terms of heat, so you can put 2 and 2 together.
