HK Rear Sight For GSG-5 Models - Great Upgrade For GSG522 Models

A great upgrade for the cheap sight that comes standard on each GSG5. This item will fit all GSG-5 models including the PK and P models. This item is an all steel HK made parts designed for combat and the toughest of environments. This will be the last rear sight you will ever need. Each HK factory sight comes as shown and is made from hardened steel so it is made to last a lifetime. Includes The detent & spring needed to drop on your GSG-5 pistol or rifle. Fits all GSG5 models and a great upgrade over the lesser quality sight that comes stock on the standard GSG-5 models.

Install instructions: Simply remove the old GSG sight and replace with the new rear sight making sure the provided ball and detent are installed in the bottom cavity hole (detent first then the spring). Place the new rear sight on in place of the replaced rear sight and use the factory hardware to secure the rear sight to the firearm. Install should take no more than a couple of mins.

"HK factory sight for GSG 5"

Frank Lamando, Jr on 1/6/2014 10:44:43 PMVerified

Overall Product Rating:

The HK rear sight appears to be a lot beefier than the original sight. Had to do minor fitting and it functions perfectly.

"You Want This Sight For Your GSG5"

Overall Product Rating:

I installed this sight on my Post Ban GSG5. Wow, it is much better than the stock notched rear sight, can acquire aim very quickly. It has numbers for each elevation adjustment on the drum like the MP5 gun it imitates. You will be glad you bought this sight. I like it better than the drum sight on my Pre Ban GSG5 also.

This rear sight is leaps and bounds better that the stock GSG sight. The detent locks solidly and it fits with no mods.

"Great Sight Upgrade!"

Overall Product Rating:

This is an awesome upgrade to the GSG-522! The factory sight was kind of lame with the vertical bars. Target acquisition is so much easier with this sight. Installation is a breeze as well.

"GSG-5 Rear Sight"

Clay West on 11/16/2012 8:08:31 AMVerified

Overall Product Rating:

I recently purchased a German Sports Gun 522. I was disappointed with its sights. Due to the patent infringement, the rear sight was a notch. I replaced it with this rear sight (easily), and the factory kit with grip, charging handle and most importantly the front sight, Now it looks and shoots like an MP5 (except in 22lr),
