Brownells 75th Anniversary - A Shooting Heritage

Replace Factory USGI Tube Or Convert Commercial Carbine To Accept Mil-Spec Adjustable Buttstock

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 aluminum construction with a tough, abrasion-resistant matte black hardcoat anodized finish. Rifle conversion also requires a carbine action spring and buffer, available separately.
