The present disclosure relates to the technical field of gun sight accessories, and in particular to a fast overturning bracket for a gun sight.
It is well-known that during use of a gun, a gun sight is suitable for use to increase a visual length when a target is far, but is ineffective at close range as it is difficult to capture the target. Likewise, other accessories on the gun, such as a night-vision device, have similar problems. The night-vision device is suitable for use at night or in dim light, and is ineffective in use at daytime.
While during use generally, when the gun sight or other accessories are mounted, a fixture is mounted on the gun firstly, then the gun sight is put on the fixture and locked by a bolt locking fixture, and it is difficult to disassemble the gun sight in a short time when close-range shooting is required. Thus, the gun simply has a single long-range shooting function, can't be fast adjusted according to use requirements, and is very inconvenient in use.
Therefore, an unaddressed need exists in the art to address the aforementioned deficiencies and inadequacies.
The purpose of the present disclosure is to provide a fast overturning bracket for a gun sight, which can achieve fast adjustment on and intermittent use of the gun sight, to solve the problems in the prior art.
In order to achieve the purpose, the present disclosure adopts the following technical scheme.
