Aim Sports USASM4STK AR-15 G.I. Style Stock Kit Mil-Spec Black

The Aim Sports USASM4STK delivers a complete G.I. style stock solution for AR-platform rifles, combining authentic military styling with modern manufacturing standards. This kit provides shooters with the classic fixed stock configuration that has proven reliable across decades of military and civilian use.

What Makes This Different

Unlike adjustable stocks that can develop wobble over time, this fixed G.I. style stock maintains consistent cheek weld and length of pull. The mil-spec buffer tube ensures proper compatibility with standard AR-15 lower receivers and buffer systems. The synthetic construction resists weather extremes while maintaining the traditional profile that won't snag on gear or vegetation.

Key Features

• Mil-spec diameter buffer tube for universal AR-15 compatibility
• Durable black synthetic stock body resists impact and weather
• Classic G.I. profile maintains low snag design
• Fixed length of pull eliminates adjustment mechanisms
• Standard carbine buffer tube threading
• Includes necessary hardware for installation
• Compatible with standard AR-15 buffer springs and weights

This stock configuration excels in situations where simplicity and reliability matter most. Law enforcement and military users appreciate the elimination of moving parts that could fail under stress. Hunters value the consistent shoulder placement for repeatable accuracy. The fixed design also meets regulations in states with restrictions on adjustable features.
