An adjustable accessory mounting mechanism for firearms has an accessory mount rail having clamp surfaces. A mount base member has a clamp structure in retaining engagement with the clamp surfaces and supports a clamp plate member for rotary clamping engagement with the accessory mount rail. A clamp retainer screw extends through the retainer opening and pivotally supports the clamp plate member for rotary locking and unlocking movement. An adjustment nut member is threaded to the clamp retainer screw and adjusts the position of the clamp plate member. The adjustment nut is located below the lower surface of the clamp plate and clamp support to prevent its catching on brush, vines and other objects during field use. |
