G3 Rear Sight Housing
It’s a no-brainer that a firearm with well-adjusted sights will shoot more accurately than one without – which brings us to the importance of iron sights. If you think shooting with unadjusted sights is tough, try shooting without any sights at all. Early fixed iron sights could not be adjusted at all, often times featuring a rear sight that was milled into the receiver itself. Now, we could discuss all the different aspects of iron sights for days (and we will get to that soon enough), but we both know that you’re here because you want to hear about the G3 rotary rear sight assembly.
The G3 rotary rear sight assembly starts with the G3 rear sight housing. Coincidentally, Keepshooting.com is now ready to offer you just that; and it’s by no means an ordinary rear sight housing – it’s an original Heckler & Koch rear sight housing. Mounted to the rear of the receiver by way of the clamping screw, the G3 rear sight housing is home to both the windage screw and the rear sight cylinder, a diopter known for its precision and adjustability. On the rear sight housing, there is a small, threaded rotating disc that allows the rear sight cylinder to be mounted. You will also find a small slot on the underside, intended to house the windage screw, which allows for adjusting the aim point to account for wind.
Without the rear sight housing, your G3 is blind as a bat. Consider the G3 rear sight housing from Keepshooting.com for $4.95 – perfect as a start to an inexpensive project.
The G3 rear sight housing can be found mounted to the rear of the G3 receiver and houses both the windage screw as well as the rear sight cylinder. 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 sights. 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.
The G3 rotary rear sight is a diopter sight, a form of aperture sight known for its high precision and adjustability. Able to compensate for both elevation and windage, the diopter sight features a small circular viewing hole meant to allow the shooter to easily and consistently center the front sight, providing more precise aiming.
