UTG 6-Position Stock Assembly Mil-Spec – AR-15/M4 Platforms

The UTG 6-Position Stock Assembly delivers adjustable length-of-pull for AR-15 and M4 pattern rifles, allowing shooters to quickly adapt for body armor, seasonal clothing, or transitions between shooting positions. The six-position carbine buffer tube provides 3.25 inches of adjustment range for a proper cheek weld and eye relief alignment across different scenarios.

Built to mil-spec dimensions for compatibility with standard AR lower receivers, this complete assembly includes the buffer tube, stock, and necessary hardware for installation. The reinforced polymer construction balances durability with reduced weight, while the textured buttpad provides a stable shoulder mount. The assembly fits standard carbine buffer and spring systems (not included).
