The price for homemade firearms ['sumpaks'] ranges from USD6 to USD20, depending on the quality of the materials and workmanship…
Sumpaks are a cheap substitute for quality firearms, with shortcomings that directly impair their usefulness. They are risky to use, are effective only at short ranges, and better for maiming than killing. Since quality and value are low, sumpaks have little or no export value.
