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.
All this talk about windage, but do we know what it actually is? Windage is the effect of wind on the course of a projectile – in this case a bullet. To adjust the sights, first loosen the rotary rear sight assembly mounting screw. Then, simply turn the windage screw in accordance with the required direction. If the point of impact is to the left of the target, move the sight to the right, and vice versa. Finally, retighten the mounting screw.

I picked up a package of these to replace the one in my G3 simply because the Century built G3 came with a stripped out head when I bough the gun.
I bough a pack of these and both looked brand new.
This is another part I picked up here because at this price I figured they were worth having for spares, may pick up another pack since I have 5 HK's total that use these.
Great price on a hard to find replacement part.
The 2 I received look brand new. Perfect finish.
