G3 Rear Sight Clamping Screw

Here we are again, coming back to one of my many comparisons that link the parts of a gun to parts of the human body. I always like to think of the iron sights on a rifle as the eyes of the rifle, as they allow the rifle to “see” its target. The rotary rear sight on the Heckler & Koch G3 is no different. Get ready for a short biology lesson on the human eye.

The G3 rear sight clamping screw can be found in the G3 rear sight housing. It is used to mount the rotary rear sight assembly onto the mounting base located on the rear of the receiver. It is an original factory part made in Germany by HK.

Spare parts are an important consideration when it comes to firearms. Like any machine, firearms rely on a series of parts to function properly, including screws. If a part breaks or fails, a repair or replacement is necessary.

It is also important to consider availability. At this time, Keepshooting.com has a wealth of authentic, original factory parts from HK for the G3/HK91/PTR91. Not only are they readily available, but also they are cheap. Now is the time to take advantage.
