SOPMOD: The best AR stock. Period.

Stoner's original stock was OK. But a fixed length of pull was never ideal. Then came the M4's adjustable stock. That stock is fine, but it's cheek weld isn't great. Comfort is lacking, and so is recoil control.

Then came the SOPMOD stock: A perfect design, cooked up by the Naval Surface Warfare Center. With its massive cheek rest, beefed up recoil pad, QD sling mounts, internal storage, and precision length of pull adjustments, it's arguably the best AR-15 stock on the market today.
