Replacement receiver extension tube is the correct length and 1.146" outside diameter for proper fit of a mil-spec carbine adjustable buttstock.
Replace a worn out USGI tube, or convert a commercial carbine or fixed-stock rifle to accept an adjustable buttstock that requires the smaller, mil-spec tube.
Six precision-machined notches on the underside grasp the stock’s locking pin securely to ensure fast, positive stock length adjustments without slippage.
One-piece 7075-T6 aluminum construction with a tough, abrasion-resistant matte black hardcoat anodized finish.
Rifle conversion also requires a carbine action spring and buffer, available separately
