Description
Designed by Archangel Armouries in the late 50's, the GwPat-60 was developed to meet the perceived demands of the 21st battlefield. It is the perfect combination of size, weight, accuracy and armour penetrating ability.
This, however, came at a cost. As a result of the GwPat-60's small 4.45mm projectile and high velocity, there was a strong tendency to pencil through targets, causing minimal tissue damage.
