Abstract
A detachable handguard for firearms having a receiver defining a handguard mounting flange. Clamp members have hook-like ends that engage the handguard mounting flange and are attached to clamp actuating levers that are pivotally mounted to the handguard. The clamp members are positioned in clamping engagement with the mounting flange and are pivoted to clamping positions to force the handguard into tight assembly with the receiver and to move the connection of the clamp members with the actuating levers over-center, thus causing the clamp actuating levers to remain at their clamping positions. Lock members secure the clamp actuating levers at their clamping positions.
Claims14
A releasable handguard mount mechanism for firearms, comprising:
- a firearm receiver defining a first handguard mount being a mounting flange defining a clamp receptacle;
- a handguard mechanism having a second handguard mount disposed for assembly with said first handguard mount, said second handguard mount being a clamp lever support structure of said handguard mechanism;
- a clamp member supported by said second handguard mount and having a clamping position retaining said second handguard mount in tight assembly with said first handguard mount and a release position permitting separation of said second handguard mount from said first handguard mount;
- and
- a clamp actuating lever member being pivotally mounted to said second handguard mount and disposed for actuation of said clamp member to said clamping position in response to movement of said clamp actuating lever member to a clamping position and for actuation of said clamp member to said release position upon movement of said clamp actuating lever member to a release position thereof.
A releasable handguard mount mechanism for firearms, comprising:
- a firearm receiver having a mount flange at the forward end thereof defining a first handguard mount being a mounting flange defining a clamp receptacle;
- a handguard mechanism having a handguard flange at the rear end thereof defining a second handguard mount of said handguard disposed for positioning engagement with said first handguard mount, said first and second handguard mounts each defining substantially planar handguard alignment surfaces each disposed in face to face handguard aligning engagement when said handguard mechanism is securely clamped to said firearm receiver;
- a clamp member having a portion thereof substantially pivotally supported by said second handguard mount and having a hook-like clamping portion engaging said first handguard mount and retaining said second handguard mount in tight assembly with said first handguard mount and having a release position permitting separation of said second handguard mount from said first handguard mount;
- and
- a clamp actuating lever member being movably mounted to said second handguard mount and having actuating connection with said clamp member being moved to said clamping position in response to movement of said clamp actuating lever member to a clamping position and being moved to said release position upon movement of said clamp actuating lever member to a release position thereof.
