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.

In stock



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.

5 pack of screws perfect for securing the rear sight to the receiver. Most look brand new. Couldn't be happier with KeepShooting!
Excellent Value

This five pack was cheaper than just a single screw through another source. I added to a big order I already had in progress. Four of the five appeared brand new - no marks on them anywhere. The fifth has a slight bit of rust on the phillips slot.
Fit my HK receiver perfectly.
Not easily replaced

After my rear sight fell off I had to find a replacement screw to put it back on
Just wish I had found these before I bought mine elsewhere since I paid this price for just one screw there
Now I keep a couple of spares on hand just in case
The pack I got here both look like new with the screw slots in clean neat condition
Good part to pick up as spare while you can get them at this price!
Look New..

Received two yesterday and installed one on my PTR91. I replaced the ugly and bulky screw that came with the rifle. This is a match for the one that comes on the HK91. The screw is metric and left hand thread- not something easily found elsewhere. If such a rifle is in your future then you need this part.
