Chas you may very well be right.
Here’s a little family tree explanation about Western Airguns:
The Rattler and Sidewinder were created by the (one of the) designer(s) of the LCS sk-19. As you can see the Rattler is nothing more than a souped up, roided up sk-19.
The sk-19 was created by stealing the design of the Huben K-1 hammerless system. If you strip away all the tacticool components it is a copy of the huben. Same valve system that allows efficient, high power on the fly.
AOA ties into all of this because they originally sold the Huben k1. Then the sk-19 comes along and AOA started selling it too. Allegedly, huben told AOA if they continue selling the sk-19 they would cut ties with them. Soon after, AOA dropped huben and continued selling the sk-19. Then, one of the designers of the sk-19 had a falling out and started another company, Western Airguns.
Huben doesn’t hide the fact that it’s made in China. LCS was vague about the sk-19 being made with imported (Chinese?) parts. On the rifle it said “made with domestic and imported parts”. The Western airgun models are likely made with domestic and imported parts as well. My guess is there are far more imported parts than domestic.
Note: LCS appears to be in litigation pertaining to patent infringement. I would not be surprised if Western Airguns will be subjected to the same litigation if they aren’t already.
