It would be a decent QOL change to make it so the Improvised Bottle Suppressor can be repaired with more Duct Tape.
class ImprovisedSuppressor: ItemSuppressor
{
repairableWithKits[] = {5}; repairCosts[] = {25};
};
Personally, I find the improvised suppressor to be OP already, a good rebalance would be to make it cost an entire roll of duct tape to craft one to begin with as well.
