Mount for attaching a device to a firearm

Apparatus for mounting a laser aiming device to a weapon having a bayonet holder and a barrel mounted flash suppressor comprising:

• a base adapted to be mounted to a laser aiming device;
• a block slidably mounted to said base;
• spring means for biasing said block toward the front end of said base;
• an open collar mounted to said block and adapted to encircle the weapon's barrel and abut the rear of the weapon's flash suppressor;
• a clip mounted to the rear end of said base and adapted to be clipped to the weapon's bayonet holder;
• means for providing a windage adjustment by altering the lateral position of said clip with respect to said base;
• and
• means for providing an elevation adjustment by raising or lowering the vertical position of said open collar with respect to said base;
• whereby a laser aiming device attached to said base is mounted to the weapon by placing said open collar about the weapon's barrel to abut the rear of the flash suppressor, sliding the base forward relative to the flash suppressor and barrel until said clip is in a position to be clipped to the bayonet holder, pivoting the rear end of said base toward said weapon, and releasing said base to allow it to slide rearward toward said bayonet holder in response to the biasing action of said spring means, thereby latching said clip to said bayonet holder.
