Historical Background

The Windham Weaponry MPC is an AR-platform rifle developed around the company’s experience in American firearm manufacturing and established direct-gas operating systems. Windham Weaponry was founded by members of the former Bushmaster manufacturing team, bringing extensive experience in rifle production, machining, gunsmithing, and assembly. The MPC, or Most Popular Carbine, represents a conventional carbine configuration within the Windham Weaponry product range. It combines the established AR-platform architecture with a modular receiver, barrel, handguard, and furniture configuration.

Technical Overview

The Windham Weaponry MPC uses a direct-gas operating system and is primarily associated with the .223 Remington / 5.56×45mm NATO chambering. Its design follows the standard AR-platform configuration, incorporating an upper and lower receiver, rotating bolt, detachable magazine system, and modular furniture.

Specifications can vary between MPC configurations and production periods. The exact model designation should therefore be referenced when confirming individual specifications.
