A Gun For Aiming: M8C .50 Caliber Spotting Rifle
The M8C .50 caliber spotting rifle served as a crucial aiming device for the M40 recoilless rifle, allowing confirmation of zero with a less detectable round. It fires a specialized 12.7x77mm tracer round, ballistically matched to the main projectile, and features a gas-operated action with a tilting bolt. Despite its specialized purpose, the M8C represents a unique engineering solution to a specific tactical problem.
