Umarex Walther CP99 Compact Ejection Port Modification

6 Comments

You may be surprised to know that the Airgun that started off my collection was purchased only about 4 years ago. As a kid I had a few Airguns growing up and then suddenly in my late 30's I just picked it up again. Anyways the Airgun this post is focusing on is the Umarex Walther CP99 Compact. This post is not intended to be a review but in summary the CP99 Compact BB Blowback BB gun has one of the nicest trigger pulls in my collection. It is so much fun to shoot, it's very well made and is reasonably priced.

The one feature,or lack of a feature that I never really like about the Umarex CP99 Compact was the molded ejection port. In other words the ejection port is not cut out of the slide on this gun but instead is molded into the slide to look like an ejection port.

That said I have noticed a few of these Umarex CP99 Compacts sporting a cut out ejection port and so I thought to myself that maybe people have been cutting the ejection port out themselves? Hey I thought about giving it a try several times myself. So I took a walk over to the Umarex US website and low and behold if you click on the 360 view, you will see that it too has a cut out ejection port. The photos on their site do not show this new feature but rather the older molded version. I can not confirm that all new CP99 Compacts will in fact have the cut out ejection port, but it does look like Umarex has moved to this updated version…

So I thought enough is enough! It's time to pull out my tools and cut into my beloved CP99 BB gun. The best way to show you what transpired next is with a series of photos. At the end of about 2 hours of work I have to say I am very happy with the end result!

This video is not really a review but rather an instructional video on how to modify a Cybergun GSG 92 Blowback BB Airgun to shoot not only in single shot (Semi Auto), but to also have the ability to shoot in Full Auto mode with the flick of the safety to the down position. (Warning - This Mod will most certainly void your warranty!)

This Modifications of the Cybergun GSG 92 is a rather simple operation, all that is needed is to remove the slide and take off the right side grip, then remove a small internal piece and file it down slightly on one end. Put everything back together and away you go. Shoot in Semi Auto or Full Auto whenever you like!

I'll be doing a Review and Field Test on it shortly...

Worlds Smallest Full Auto BB Gun

This is a video I posted on YouTube a while back that has gotten a lot of views (Now Over 300,000). It's basically me and a friend shooting a couple of guns. The first set of guns (One in each hand - Tomb Raider Style) are two Walther CP99 Compacts made by Umarex. The CP99 Compact is a great little BB gun with a very fast and light trigger pull.

Next up is another Umarex product, a Walther PPK. This one is moded to fire Full Auto, making it one of the smallest Full Auto BB Guns. Too bad it's all over so fast! I'll look at doing some proper reviews of these fine Airguns down the road...
