STRIKE INDUSTRIES ADVANCED RECEIVER EXTENSION – FDE (7-POSITION)

Bring enhanced functionality and a custom aesthetic to your build with the Strike Industries Advanced Receiver Extension in FDE. Designed to upgrade a critical yet often overlooked component of the AR-15 and AR-10 weapon systems, this 7-position mil-spec diameter buffer tube features scalloped external surfaces that shave unnecessary weight while reducing friction with tight-fitting stocks.

Machined from ultra-durable 7075-T6 aluminum, this receiver extension offers vastly superior strength compared to standard 6061-T6 buffer tubes. It features a supported buffer retaining tab for easier receiver indexing and long-term retainer reliability. Providing finer length-of-pull adjustments across seven positions, this lightweight, Flat Dark Earth (FDE) extension is compatible with standard AR15 receivers as well as the Strike Industries Pit Viper Stock.
