A latching mechanism for engaging and disengaging a fore-end stock to and from a barrel assembly of a firearm. The mechanism features a unique sliding finger-operated integral latch and lever assembly which releases the fore-end stock from the barrel. The locking latch slides into snap-action engagement with a rail extending from the barrel assembly. The rail comprises a novel inclined plane which enhances the lock-up of the latch. This latching arrangement provides continuous fit even after extensive firing of the gun. The slidable latch provides for quick take-down. A unique adjustment plate, featuring an eccentric lock nut, is provided to insure proper fit to the barrel assembly.
