Ranged weapons in ancient times could be simple, fixed power, rapidly assembled operations, or highly complex, variable power, variable range devices of incredible precision. By altering the weight of a counter balance, or tension on ropes and springs, experienced artillery officers could aim projectiles with incredible precision. Trojan Firearms LLC gas blocks mirror these applications with both fixed orifice and adjustable variants.

This leaves a smoother, softer machined face which seals onto the barrel gas port better than other material options.
