Detailed Features
Forged 7075-T6 aluminum is the standard for quality AR-15 lower receivers -- it gives a better strength-to-weight ratio than 6061 and holds threaded inserts reliably over a long service life. YHM machines this receiver entirely in-house.
The oversized magazine well chamfer speeds up reloads by giving the magazine a larger target to index into during a change, useful in competition and any situation where speed matters.
The hardcoat anodized finish resists corrosion and wear without adding thickness that would affect fit with standard mil-spec components.
Usage
The YHM-125 is a solid foundation for a custom AR-15 build, whether that build is oriented toward competition, home defense, or general range use. Universal compatibility with mil-spec uppers and all PMAG generations keeps component selection open.
