Tti Mpx Stock Adapter

The Taran Tactical Innovation TTI MPX Stock Adapter is a dedicated interface solution that allows shooters to pair standard AR-15 buffer tube stocks with the Sig Sauer MPX platform—one of the most proven and reliable pistol-caliber carbines in tactical service today. This adapter bridges a genuine ergonomic gap: it eliminates the need to purchase proprietary MPX-specific stocks and instead leverages the vast aftermarket ecosystem of AR-15 buffer tube accessories.

Engineered to precision tolerances, the adapter maintains a clean mechanical interface with the MPX receiver while accepting any standard AR-15 buffer tube stock without modification. The black finish provides consistent aesthetics across modern tactical setups. At 0.13 lbs and compact dimensions (3 x 1.5 x 4 inches), it adds negligible weight and no functional bulk to your platform. This is a straightforward engineering solution—no binding, no fitment surprises—designed to work the first time.

Operators and serious shooters running the MPX in patrol carbine, CQB, or training roles benefit immediately from the ability to select stocks based on mission fit rather than platform availability. Whether you're running a fixed A2-style, collapsible six-position, or specialized tactical stock, this adapter eliminates compatibility constraints and lets you optimize length of pull, cheek weld, and storage integration to your specific loadout. For armorer-level versatility across an MPX platform, the TTI adapter is a practical, cost-effective upgrade.
