ABSTRACT:
BACKGROUND OF THE INVENTION
Flip up gun sights are currently being used on guns including AR-15 and M-16 rifles, but the sight arm of the sights are subject to being displaced downwardly at inopportune times, examples of which include moving through trees or bushes, climbing through a window, or maneuvering around vehicles. The current flip up rear sight becomes useless if a foreign object pushes up against the aperture.
What is needed is a flip up front or rear sight which is immune to being rendered inoperative by environmental conditions of use.
SUMMARY OF THE INVENTION
The basic concept of the flip up sight of this invention is applicable to both the front and rear sights. In each case a base member is provided which may be attached to the flat top AR upper receiver including the rear most slot for the rear flip up sight. Other optical or night vision devices may be mounted on the same receiver as the flip up rear sight only requires a minimum of space.
A sight arm is pivotally connected to the base member and is spring biased downwardly against a support arm pivotally attached to the opposite end of the base member and which is spring biased upwardly into engagement with the bottom side of the sight arm. Cooperating lock means are provided at the outer end of the sight arm and upper end of the support arm to lock the sight arm in a raised position making it resistant to impact from foreign objects that would otherwise cause it to be displaced from its raised operative position.
When the sight arm is to be lowered it is first raised off of the support arm and the support arm is then pivoted downwardly under the sight arm which is also pivoted downwardly on top of the support arm thereby locking it in a lowered position flush against the upper receiver. When not in use the flip up sight measures only ⅝″ tall which means the rear sight will not interfere with the use of popular combat sights such as the AimPoint CompM2, Trijicon ACOG, and EOTECH holographic sight. If the operator experiences a failure with his AimPoint or EOTECH sight, then he can still utilize the flip up rear sight by looking through the useless optical sight.
